Abstract: This article is devoted to the study of petroleum properties of Paleozoic deposits of the southern part of the Pre-Urals foredeep on the basis of which the probable oil-material strata of the section were substantiated. The reason for this research was the low efficiency of geological exploration in the region of the study due to underestimated geochemical criteria. According to the results of the research it was found that within the southern part of the Pre-Ural foredeep, deposits of Middle-Upper Carboniferous and Lower Permian systems are characterized by oil and gas deposits, which are characterized by good generation potential

Abstract: In the Iraqi Kurdistan, the most significant oil deposits are concentrated in the Cretaceous and lower Miocene sediments. In this paper we used data on the recently discovered Sarqala and Shakal oilfields. The Lower Miocene formations of Euphrates and Jeribe are the main target objects of the tertiary oil and gas system in the Iraqi Kurdistan. The formations are composed of carbonates with a few interbeds of evaporites of the Dhiban formation. The rocks of the studied formations are affected by a number of diagenetic processes, including dolomitization, micritization, cementation, neomorphism, leaching, compaction, styllolitization, pyritization and anhydration. The most significant of these are the processes of dolomitization, dissolution, neomorphism, cementation and compaction. The processes of dolomitization and dissolution improve the quality of reservoirs, while neomorphism, carburization and compaction have a negative effect. Fracturing plays a significant role in the increased porosity and permeability of the rocks studied, mainly in calcareous mudstone and wackestone.

Lithological and facial characteristics of formation of reservoir rocks of middle permian sedimentations in Western Sulige gas field (China)

Authors: Mingyu HE is postgraduate student of thе Department of General and Oil and Gas Production Geology of Gubkin Russian State University of Oil and Gas (National Research University). E-mail:

Abstract: Based on the analysis of core and thin sections of the middle Permian sedimentations in the western Sulige gas field, three main types of sedimentary facies have been identified i.e. meander, anastomosis and braided river. This paper analyzed sedimentary facies in a single well, and determined the lithology and sedimentary facies of each layer. The construction of paleogeological profiles in the profile and paleogeographic maps on the plane is based on the results of well logging data and comprehensive analysis of each well. It was revea- led that in this region the paleochannel sandstones in the lower part of forma- tion He8 (h8x) are characterized by braided river. In the upper part of forma- tion He8 (h8s) braided river changed into meander and anastomosis. In the formation of Shanxi1 (s1), two or three anastomoses developed in the direction from north to south

Construction and practical application of four component diagram for bazhen suite sedimentary rocks

Abstract: A new approach to Bazhen suite rocks typing is proposed. This is based on the mathematical framework and conforms to the conventional sedimentary rocks classification. This approach takes into account the quantity of four basic Bazhen rocks components. They are kerogen, carbonate, clay and silica. Using these data a four component tetrahedron diagram was created. This diagram helps to observe the mutual relations of the complicated Bazhen rocks, to find some genesis correlations, define the unit boundaries and the most perspective reservoirs in the normal frameworks of the Bazhen formation

Abstract: Optimization of the choice of facilities for repair work and the volume of their financing can be carried out on the basis of reliable diagnostic data on both the technical condition and integrity of the pipe itself and the soils of the near-pipe space. Traditional methods of diagnostics are not quite suitable for monitoring and forecasting emergencies in areas of natural and man-made risks (landslides, karst, tectonic disturbances, faults, underground mining, etc.). A significant step in solving the problem can be made by incorporating into the diagnostics system radio wave methods, which have been successfully implemented at a number of facilities of OOO «Gazprom». These are aimed at eliminating the possibility of accidents at the earliest stages of natural and man-made processes.

Abstract: The article is devoted to the reasons causing the intensification of carbon dioxide corrosion. Methods of its identification are considered on the example of production of wells of the Karazhanbas field. The results of the studies showed the pos-sibility of using X-ray structural analysis of corrosion deposits as a method of corrosion monitoring. The necessity to isolate wells with a pH value of 6,5 and below was revealed with an increase in partial pressure up to 3 kPa and above at the temperature of the produced fluid of 50 °C to a complicated pool for selecting equipment in corrosion-resistant design.

Abstract: Orthogonal cylinder-bevel gears have been applied since ancient times. The main advantage of such transmission versus the traditional conical one is the possibility of some axial displacement of the gear that significantly simplifies the mounting of the gear. However, the geometric calculations required in the manufacture of this type of transmission are extremely complex. Therefore, effective software, that would simplify the geometric modeling of transmission elements, is needed. The article describes the scope of orthogonal cylinder-bevel gears in modern engineering. An algorithm for the geometric calculation of the elements of cylinder-bevel gear, implemented using the application program module developed by the authors, is presented

Abstract: The article shows the need to study the chemical stability of fuels for jet engines, which contain components of deep oil refining, and suggests a method for studying the chemical stability of fuels for jet engines. Based on this method, studies of fuels for jet engines of various production technologies have been carried out. The minimum chemical stability has a fuel based on kerosene fraction of hydrocracking. This fact is explained by the conversion of the hydrocarbon composition of the kerosene fractions in the hydrocracking process
