» The Effect of Gas-Line Wrapping Alternatives on Stress-Corrosion Resistance

The article covers the effect of gas-line wrapping alternatives on stress-corrosion processes and, thus, on gas line insulation strength. All pipes of any manufacturers are known to be susceptible to stress-corrosion, particularly those made of sheet metal produced by controlled rolling. Manufacturers of tubular goods often explain stress-corrosion of pipelines by their poor electrochemical protection, temperature operative conditions and their wrapping quality. But the study has shown stress concentration to be most important in crack birth and development, therefore, a key factor is the limiting state of pipe walls. Besides, a pipeline wrapping can keep the crack birth and development in check due to its pipe squeeze force, thus extending the life of a pipeline. The study has analyzed three types of corrosion control coatings (three-layered extruded polyethylene coating, polyurethane two-component coating, polymeric insulation tape) and has presented their essential descriptions. The algorithm to calculate the effect of insulation materials on pipe resistance to corrosion DN 1400 for 15.7 mm wall thickness is given in the article. The calculation data are shown in form of a table for visualization making it possible to conclude that a maximum stress reduction in pipe walls can be achieved by a three layered polymeric coating, thus increasing pipe resistance to stress-corrosion processes by 9.0.10–3 %.

Keywords: pipeline wrapping, stress-corrosion defect, stress, three-layered extruded polyethylene coating, polyurethane two-component coating, polymeric insulation tape.

» On the Mechanism of Blistering and Bubbling on the Surface of Polymer Coatings of Oil-Field Pipeline Elements and Borehole Pipe Strings and on the Checking Technique for Coatings to Resist these Defects Formation

The article presents the findings on the effects of gas-liquid medium, its temperature and overall pressure, partial pressure of gasses in gas-liquid medium on the appearance and dielectric continuity of inner epoxy coatings for oil-field pipelines and steel elements in tubing strings. The studies have been conducted by the experts from the Gubkin Russian State University of Oil and Gas (National Research University) polymer coating design laboratory for oil and gas facilities to assess the objective character of the industry-applied checking techniques for the appearance of inner epoxy coatings of steel tubular goods, in particular the high-pressure steam (autoclave) test procedure developed at Research and Development Center “Samara” for the rapid resistance analysis of anti-corrosion coatings to blistering and bubbling. The procedure includes autoclave tests of coatings in gas-liquid medium at increased temperatures and pressures within 24 and 240 hours with subsequent quick and slow depressurization. The studies have proved the depressurization-rate reduction from 5.0 to 0.005 MPa/sec at 4.0 MPa initial overall pressure of model gas-liquid medium to have no effect on blistering and bubbling of the coating surface and dielectric continuity of the coating. Yet, the formation of blisters and bubbles on the coating surface and their cracking greatly depend on the gas-liquid overall pressure and temperature, СО2 partial pressure at the temperature of max. 100 °С and steam at the temperature of over 100 °С. The studies have also shown that the testing periods of 24 and 240 hours are not sufficient since coatings successfully tested for the resistance to blistering and bubbling during 24 and 1000 hours have failed similar 70 days’ tests. Besides, according to the authors, the idea of Research and Development Center “Samara” experts on the principal cause of coating surface blistering and bubbling does not represent the facts. The authors conclude that explosive decompression (high rate of depressurization) does not cause such defects – they are of osmotic nature. In addition, osmotic blistering on epoxy coatings of certain steel pipe producers is mainly explained by the presence of water-soluble substances in the coating composition and breakdown in the coating process, in particular the presence of water-soluble matters on the metal surface ready for painting, moisture adsorption on this very surface due to increased humidity of the environment or compressed air used for liquid blasting or post-blasting dust cleaning of the surface to be painted. The data analysis of the study carried out at the Gubkin Russian State University of Oil and Gas (National Research University) has made it possible to develop the recommendations given in the article on the model gas-liquid media compositions for periodic anti-osmotic blistering tests of inner epoxy coatings and testing conditions in these media.

Keywords: oil-field pipeline, tubing string, inner epoxy coating, bubble, local blister, gas-liquid medium, pressure, increased temperature, carbon oxide, steam, decompression, osmotic blister, depressurization-rate effect, mode of periodic tests.

» The Development of a Parametric Model of a Flowing Part with Impeller and Vaneless Diffuser of the Centrifugal Compressor Stage

The article presents the results of the parameter-oriented solid model development for the flow-through channel of a two-section stage centrifugal compressor with an axi-radial impeller. The solid model has been developed in the parametric designing system - ANSYS Design Modeler - to be further introduced into the algorithm of multiparametric and multicriteria optimization. The model has been built on the parameter base resulting from gas-dynamic computations. The research carried out also included examination of the diagrams and selected geometrical parameters of the stages, identification of control parameters and ranges of their variations. Meridional profile of the model developed within the framework of the research is of high versatility and can be used for any impeller diameter. The results have indicated that the automated designing process makes it possible to cut R&D expenses due to a considerable time reduction and excluded natural experiment need to develop a centrifugal flow-through channel. In addition, the proposed designing method provides for a possibility to optimize geometrical and gas-dynamic model parameters basing on the methods of computational gas-dynamics and within the shortest possible time to produce a highly effective flow-through channel. Another advantage of the method is to get a chance of creating two-tiered axi-radial impellers and developing a model for interdisciplinary analysis of impeller strength considering distributed fields of temperature and pressure. In general, the method proposed allows to create a fully automated R&D procedure followed by a multiversion analysis based on the current interdisciplinary CAD/CAE-approach using the extreme efficient equipment - supercomputers.

Keywords: centrifugal compressor, two-element stage, 3D impeller, parametric model.

» Lithofacies Zoning as a Basis for Updating the Dependencies of Reservoir Properties for Complex Terrigenous Reservoirs of the Vendian of the Chayandinskoe Oil and Gas Condensate Field

The heterogeneity of productive sediments of the Vendian of the Chayandinskoye oil and gas condensate field causes an inherent ambiguity of the dependencies between the reservoir properties. In order to update the petrophysical dependencies for the Vendian deposits of the field, lithofacies zoning was carried out on the basis of a study of core material and geophysical surveys of wells taking into account regional structure. One sedimentation cyclite was revealed in the Botuobinsky horizon. The development of the cyclite took place in the facial conditions of the bar body and the shallow shelf. The Khamakinsky horizon, as the study showed, is divided into three cyclites, represented by the fluvial and tidal delta facies. At the same time, using the example of cyclite KhM1, there is a link in the development of reservoirs with degraded reservoir properties and zones of sandstones halitization and carbonatization, while cyclite KhM2–1 is characterized by higher reservoir properties due to a lower degree of development of secondary processes. In the section of the Talakhsky horizon, three sedimentation cyclites are distinguished, represented by the facies of the alluvial-delta plain, tempopary beds and the talus fan of temporary flows. The sandy, gravel-sandy and sandy-aleuritic rock associations of the upper unit (TL1), composed of alluvial-deltoic facies, have the best reservoir properties in the Talakhsky horizon. A distinctive feature of the unit compared to the lower cyclites are more fine-grained deposits and the absence of a conglomerate component in the composition of the rocks. Thus, the laying of horizontal wells of production wells is most effective in this part of the reservoir. According to the results of the study, regularities of changes in reservoir, petrophysical, and mining properties of the layers, depending on the facial conditions of formation of the productive horizons of the Chayandinskoe field, are identified. As an example of update the dependence between formation reservoir properties based on the results of lithofacies zoning, the dependence of the permeability coefficient on the effective porosity coefficient was researched. The correlation of this dependence and the facial conditions of the Botuobinsky horizon and the cyclites of the Khamakinsky and Talakhsky horizons has been made. The results obtained are recommended for practical use, taking into account the developed schemes of the distribution of lithofacies.

Keywords: lithofacies zoning, productive sediments, flow rate, reservoir properties, petrophysical function, coefficient of permeability, coefficient of porosity.

» Study of Some Organic Disulfides as Antimicrobial Additives to Lubricating Oils

Research of dependence between chemical structure of organic disulfides and their biocide effectiveness is of a great importance for directed synthesis of effective biocide lubricant additives. The article describes synthesis methods for some sulfur-organic compounds of linear structure and those containing fragments of aromatic hydrocarbons, as well as their physical and chemical properties, above all, activity against mold fungi Aspergillus niger, Cladosporium resinae, Penicillium chrysogenum, Chaetomium globosum and bacteria Mycobacterium lacticolum, Pseudomonas aeruginosa. In the process of the research infrared spectra of the compounds synthesized were registered in the interval of 400–4000 cm–1: liquid samples – using liquid cuvettes, solid samples – using oil suspensions M-8. In this article there have been given results of the quantum-chemical analysis of ionization potentials and dipole moments of synthesized compounds, including amylheptyldisulfide, amylallyldisulfide, amylthioethyloctyldisulfide, octyldisulfideacetamide, benzyl merсaptan, benzylamyldisulfide, amylcyclohexyldisulfide. Efficiency of synthesized disulfides as antimicrobial lubricant additives is shown, with a number of compounds (amylallyldisulfide, octyldisulfideacetamide, benzylamyldisulfide, amylcyclohexyldisulfide) being stated to have both bactericidal and fungicidal properties. Amylallyldisulfide has been proved to possess the highest antimicrobial effectiveness, and according to the authors this fact is conditioned primarily by the compound molecular structure. The effect of structural parameters on antimicrobial efficiency of M-8 lubricant additives has been examined. The results suggest that in general there is a certain correlation of antimicrobial properties of disulfides under examination with calculation data of geometrical and electronic structures (ionization potential and dipole moment).

Keywords: organic dialkyl disulfide, reactivity, quantum chemical parameters, antimicrobial additive, ionization potential, dipole moment.

» Effectiveness Testing of the Anti-Turbulent Suspension Additive М-FLOWTREAT for Pressure Oil Pipelines

The article presents effectiveness test results of the anti-turbulent additive M-FLOWTREAT of grade C used in pressure oil pipeline sections. The test consisting of five stages also included the investigation of a relative reduction of hydraulic resistance in turbulent flow due to the use of the additive in concentration of 0–30 g/t, inclusive of transit pumping from the dead pump station through the two track oil heaters to the oil-transfer station. Under the existing additive oil transfer technology the test conducted has shown an increased flow rate. The article describes the effectiveness prediction algorithm for the use of M-FLOWTREAT of grade C in concentrations of 10, 20, 30 g/t, resulting in 21.59, 49.86 and 59.08 %, correspondingly. The possibility to shutdown outer pumping while continue tank oil transportation has been proved: additive effectiveness in concentration of 30 g/t, when oil transporting by pressure pipelines at disconnected outer pumping, has amounted to 55.24 %. The capacity estimation data for the first and second pressure pipeline sections are given on the basis of the tests carried out. Pressure characteristics of oil pipeline sections when oil transporting with/without the additive in concentrations of 10, 20, and 30 g/t are presented in the article.

Keywords: anti-turbulent additive, M-FLOWTREAT, hydraulic resistance, turbulent flow, pressure oil pipeline, effectiveness.

» Algorithm of Hydraulic Calculation of Technological Section of Pipeline using Anti-Turbulent Drug Reducing Agents

The article deals with the question of hydraulic calculation of stationary modes of the technological pipeline section using anti-turbulent drug reducing agents to reduce the hydraulic resistance of transported liquid. By the term “technological section”, we imply a section of a pipeline including one head and several intermediate pumping stations, operated in mode “from pump to pump”. The proposed algorithm considers the technological section of the pipeline as a single hydraulic system, the work of which components (stations and spans between them) are interconnected and interdependent. The injection of drug reducing agents on any stage changes the operation mode of other stages. Therefore it is impossible to calculate the operation mode of the technological section and to predict the value of total energy consumption and to make conclusion about the efficiency of the drug reducing agents, without failing to consider the operation of the entire technological section as a whole, taking into account the specific characteristics of the pump-power equipment of individual pump stations. The proposed algorithm for multivariate calculations of complex oil pipeline, allows us to solve this problem. The results of the work are intended to solve an important problem of energy efficiency at the stage of project planning.

Keywords: oil pipeline, technological section, hydraulic modes, flow-head characteristics, electric power consumption, anti-turbulent additives (drug reducing agents), hydraulic resistance coefficient, universal equation of resistance, iterative.

» Improvement of Complex Technology of Enchanced Oil Recovery

Application of technologies of straightening the injectivity of profile is quite important for fields on middle and late stages of development. Complicated geological conditions and existence of natural and technogenic fractures determine the application of modern complex technologies focus both on fracture isolation and redistribution of filtration flow in formation. Complex technology SiXell used in high-temperature formations with low permeability requires successive injection of polymer solutions, gel-generate compositions based on aluminic salts and polymer solutions. Polymer solution is represented as a low concentration solution required to prevent dilution of gel-generate compositions. One of the most common problems connected with these compositions is high polyacrylamide adsorption that results in its gelation in bottom-hole zone and decreasing of operational benefit. The authors of the article conducted a study to test the hypothesis that the addition of a crosslinker (a salt of polyvalent metal) to the solution can reduce the adsorption of polyacrylamide on the rock and result in deep injection of composition into the formation. The static adsorption of solutions of different brands linear and cross-linked polyacrylamide was researched to simulate reservoir conditions. In addition the measurement method to determine concentration of polyacrylamide was developed and put in practice. The optimal brand and concentration of polyacrylamide were determined to use in complex technology of straightening the injectivity of the profile.

Keywords: alignment profile injectivity, enhanced oil recovery, polyacrylamide, static adsorption, X-ray fluorescence.

» Upcoming Trends in Work Directions for Intencifying Oil Production from Carbonate Reservoirs

Despite the continuous improvement of the methods of hydrochloric acid treatment, that includes the development of new high-performance corrosion inhibitors, problems associated with corrosion of oilfield equipment and the subsequent introduction of large quantities of iron (III) ions into productive layers can’t be avoided. The ingress of iron compounds into the ground formation promotes clogging of pores and efficiency of production stimulation decrease. A number of methods are considered in the article aimed at creating a reaction medium just prior to injection of the acid composition or obtaining an acid in the reservoir conditions. Application of these methods make it practically impossible to eliminate the entry of iron compounds into the formation. In the course of the review it was revealed that one of the most promising methods for increasing the efficiency of work on the production stimulation from carbonate reservoirs is to obtain a reaction medium at the bottom of well by reacting neutral individual components, with their separate delivery along the tubing (tubing) and annular space. The acid is formed by the reaction of ammonium salts and an aqueous solution of formaldehyde (formalin). Said reagents are neutral with respect to steel equipment, and the iron content in the reagents themselves does not exceed 0.001 %. By means of using these reagents, a multiple reduction in the amount of iron introduced into the formation is achieved. In addition, laboratory studies of ammonium and formalin salts aimed at studying the kinetics of the reaction and determining the dissolving properties of the acid-generating mixture were carried out. The research conclusions made it possible to substantiate the prospects for the development and application of the method of inflow stimulation by producing a reaction medium at the bottom during the reaction of ammonium salts and formaldehyde.

Keywords: inflow stimulation, acid treatment, hydrochloric acid, iron ion, acid-generating mixture.

» Efficiency Assessment of Gas Discharge Limitation Technologies while Simulating Oil Fringes Using the Navigator Bundle

Rationale development of the reservoir with a massive gas cap is relevant for a lot of oil and gas companies around the world. The main problems of such challenge are the formation of gas cones, which lead to gas breakthroughs to production wells. This process reduces technical and economic indicators and does not allow to achieve high values of oil gas recovery factor. The article describes the methods of the development of reservoir with a gas cap, the classification of limiting gas breakthrough technologies is given. Methods of forming blocking screens and using inflow control devices are analyzed. The authors describe the process of simulating the gas cap of the reservoir in the form of a tracer in the tNavigator. The article considers three options for oil recovery from the gas cap reservoir using the example of the tNavigator training model: operation of vertical production wells, operation of horizontal exploitation wells, formation of an insulating screen at the gas-oil contact. Authors suggested methods for increasing the efficiency by analysing the results of each options. For example it is suggested to use of an adaptive inflow control system and the formation of an insulating polymer screen with an extensive water barrier.

Keywords: development of oil rims, gas restriction technology, gas coning, gas breakthrough, gas cap, simulating, tNavigator.
