Key words: grouping, cluster analysis, sheshminskiy horizon, Tournasian stage, oil rock parameters.

Today on the territory of Republic Tatarstan discovered more than 207 oil fields uniting approximately 3000 oil deposits. Of particular interest is the grouping of oil fields on parameters of porosity, oil rock saturation and permeability, oil density, viscosity, resin and sulfur content and etc. The grouping allows to estimate similarity and dissimilarity of productive layers, to multiply successful technology and layer influence methods among object of one group, allows to confirm recovery schemes and enhancing oil recovery methods and etc. The grouping on the base of cluster analysis and geo information systems is shown on the example of ufimian and tournasianoil deposits.

Key words: tectonically dependent hydrocarbons traps, tectonic fractures, seimic, thermal, gravitational and magnetic fields, tectonic blender, oil and gas bearing capacity.

The majority of the hydrocarbons traps is tectonically dependent and influenced by the geodynamic field (its components). After geodynamic transformation, original primary traps changed to various degrees and formed secondary accumulations, both becoming seismogenic, which emphasizes connection between seismicity and hydrocarbons bearing capacity. Analysis of geodynamic field’s components should be directed at recognition of the tectonic blender, defining development of primary and secondary HC traps.

In the old oil fields it is observed reorientation exploration in shallow horizon sediments, accompanied by generalization and re-interpretation of the accumulated geological and geophysical information on the new technical and methodological level. The object of study – is Maastrichtian deposits of the Upper Cretaceous of Eastern Stavropol, is traditionally considered as one of the most promising oil and gas complexes. However, despite the proven industrial productivity, the total oil and gas exploration Upper Cretaceous deposits played a very limited position. This is due to the complexity of the structure of the Maastricht natural reservoir, as well as the specific conditions formation and distribution of oil, what about-Understands the difficulties of their exploration and development. Some difficulties also arise in calculating reserves hydrocarbon resources in carbonate reservoirs in terms determination of the useful capacity. In connection with this are highly relevant researches aimed at the study of factors affecting on-formation of complex natural oil reservoirs in the upper-Cretaceous complex of East Stavropol, which may be increase effectively engage hard-to-reserves owls in the development.

The main objective of this work is oil and gas potential evaluation in Upper Jurassic – Cretaceous, Paleozoic – Lower - Jurassic Ust-Tym mega depression deposits based on paleotectonic reconstruction and paleotemperature modeling. The thermal history of all oil generation series in the cross section of 10 deep wells was reconstructed. Sets of maps showing the distribution of geotemperature and intensive oil generation areas location in Bazhenov and Togur series for 10 key sedimentation time-periods were constructed. These were identified due to the main oil generation zone geotemperature. The integrated ratio including oil geotemperature generation zones and generation time period for separate studied areas was determined. Schematic density maps for primary-accumulated Bazhenov and Togur oils were constructed. Efficient prospect and exploration survey for Cretaceous and Upper Jurassic, Middle Jurassic, Lower Jurassic and Paleozoic oil and gas generation complexes within the separate zones and the mega depression edges was recommended.

Influence of various factors on efficiency of hydrogen sulfide removal using amino formaldehyde-based compositions has been studied. It has been found that the main contributors to efficiency of the process are specific consumption of the chemical agent and the method of feeding and mixing thereof with the oil stream. Increased oil stream temperature facilitates the process, while overall duration of the process determines largely the final concentration of hydrogen sulfide in stock-tank oil.

Key words: oil mixture, depressant additives, pour point, effective viscosity, shear stress.

Results of researches of possibility of improvement of refrigerant flowing properties of the West Kazakhstan oil mixture transported on the main Uzen – Atyrau –Samara pipeline are given in the article. The optimum heating temperature of the oil mixture and putting additives is 80-90 °C. Mixing Western Kazakhstan oil with low-paraffinic oils Emba and Aktobe fields increases its susceptibility to heat treatment (60 °C) and the action of depressants.

Key words: oil treatment parameters, water-oil emulsion, a coalescing element.

The results of studies of an oil emulsions dehydration process in laboratory devices with coalescing nickel foam fillings are presented. The possibility of estimating the oil emulsions dehydration level depending on the duration and intensity of their treatment with coalescing fillings is shown. Obtained results allowed to upgrade the method of determining the design technological parameters of the preliminary and final oil dehydration.

Key words: energy efficiency, energy savings, energy inspection.

The article presents the consideration of the practical experience of in-house management inspections within Surgutneftegas OJSC of energy echnology complexes. The questions of energy inspection methodologies are discussed. The electrical energy consumption structure in terms of technology complexes is given.

Key words: production well, sidetrack, quality cementation, environmental safety, completion.

One of the main problems of environmental safety during construction and operation of oil wells is the preservation of tight lining and insulation permeable reservoirs along the borehole in secondary completion fluids to prevent behind-casing and cross-flow between layers flows. Slotted abrasive jet perforation is proposed to reduce the risk of negative effects on the environment during the perforation of sidetracks. Сlassification and analysis of the sources of environmental pollution during drilling are performed.
