Recently the steady tendency to magnification of bulks of extraction and haul, so-called anomalistic crude oils high in paraffin and emulsion which one have high temperatures of congelation and, accordingly, anomalistic rheological behaviour was outlined. Thus, for problem solution on magnification of bulk of pumping-over of emulsion and high-viscosity, high-wax oils developments new and optimisation of applied technologies of haul crude oils taking into account their rheological behaviour and operating characteristics of oil pipelines are indispensable. On the basis of cavitation processes it is possible to erect communal laws of regulation of physical and chemical properties crude oils, to use in technology of a pipeline transportation of emulsion and high-wax oils, by meliorating of rheological behaviour of flowed through oil. For an appraisal of influencing of the maintenance of a condensate - of a diluent on rheological and physical and chemical indexs of heliportable water cut oils at various temperatures laboratory investigations have been held. For experiments the condensate and oil hallmark with an original water cut of 38 % and 50 % have been used. Tendered mathematical formulas in comparison with an additivity rule yield more comprehensible results and will well be matched the data of experimental definition of gravities. Thus mean inaccuracy of gravity determination of a mixture does not exceed 0,2 %.

RESIDUAL LIFE ASSESSMENT IS LONG MAINTAINED VERTICAL CYLINDRICAL TANKS (P. 14-18)
The paper proposed to enhance the security of advanced algorithms assesses the residual life long maintained vertical cylindrical tanks in terms of corrosion damage. When calculating the resource is taken into account the measurement error of the wall thickness, the statistical spread of the original data and operating conditions of the tank.
KEYWORDS: residual resource, reservoirs, methods, non-destructive testing.
RAPID METHOD FOR DETERMINING PARAMETERS
EERGOEFFEKTIVNOSTI GAS COMPRESSOR UNIT (P. 19-22)
Kitaev S.V., Dr. Sci. (Tech.), Prof., docent of Department of Transport and Storage of Oil and Gas
On their own needs gas trunk line spent about nine percent of the produced gas, therefore reducing gas consumption for own needs is an urgent task. When using the gas pumping units on gas pipelines on gas pipelines control of energy consumption is based on energy efficiency indicators identified using computational methods. The structure of the energy efficiency of gas compressor units are efficiency and specific consumption of fuel gas. For ease of calculation of energy efficiency in the work produced virtually grounded rapid method of determining the specific consumption of fuel gas in the parameters of the work of gas pumping units controlled standard automation system. The proposed analytical dependence can be integrated into the station monitoring system to choose whether to advance empirical coefficients for a particular type of unit.
KEYWORDS: gas pumping units, energy efficiency indicators, efficiency, specific consumption of fuel gas.

SCIENTIFIC BASIS FOR THE CREATION OF EFFECTIVE SYSTEMS FOR THE DEVELOPMENT OF HYDROCARBON FIELDS
ASSESSMENT OF POTENTIAL CAPABILITIES OF «LAYER-WELL» ENERGY SYSTEM (P. 37-41)
Mamedov A.V., Cand. Sci. (Tech.), docent of Development and exploitation of oil fields Department
The traditional methodology in analysis of hydrocarbon field development in most of cases does not consider evolutionary mechanism of subsurface system, while there are variety of factors associated with the oil production process may create instability in this subsurface system.
To achieve optimized production and to avoid unnecessary energy loss, the production and operation system requires frequent adjustment of well lifting regimes and regular research and analysis. Here shown the ways of improvement of the technological characteristics based on operational coordination of production facilities. This is especially important in the development of offshore fields.
The analysis of revealed correlational groups showed the possibility of diagnosing changes of synergistic state of the reservoir system, well aligned with results of fractal analysis of well stock data.
The proposed approach allows you to quickly identify potential capabilities of effective energy in oil saturated multilayers and select proper geological and technical activities, taking into account its evolution, and minimize energy losses.
KEYWORDS: regime, work, facility, well, analysis, correlation, group, decision.
