OIL DEPOSIT DEVELOPMENT METHOD Russian patent published in 2014 - IPC E21B43/16 E21B43/27 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to oil producing industry and may be used successfully for development of oil and gas deposits with hard to recover reserves opening up both carbonate and terrigenous reservoirs, including oils of high viscosity. The concept of the invention is as follows: the method includes oil production from producers, injection of displacement agents to injectors, surveying of geological environment in productive strata and use of physical simulation techniques, registration and analysis of radiated emissions from geological environment both before and upon simulation. According to the invention spatial-temporal aggregate of simulation centres is defined by registration and analysis of time series of radiated emission signals from geological environment areas that cover fields with different fluid saturation, fracturing and stress as well as node areas of high instability within the square area and volume of strata. At that the aggregate is determined before simulation and corrected in its process. Analysis of radiation emission signals is made with consequential transformation of time span and determination of time differences in variation cycles of radiation emission intensity corresponding to fractal substructures of the environment ranging them from the smallest ones. Thereafter in the determined centres against the square area or volume the areas or time spans are specified from which or in compliance with which polyfrequency wave and/or pulse action is made simultaneously at two or more frequencies. At that data on oscillation frequency or pulsed frequency are specified with corrections in process of simulation against the above time differences determined in analysis process of radiation emissions.

EFFECT: improving efficiency of the development method due to simulation of strata by physical emissions thus providing effective oil influx to wells and expanding functionality of the method.
