MULTILAYER OIL DEPOSIT DEVELOPMENT METHOD

摘要

FIELD: oil and gas industry.SUBSTANCE: invention relates to oil industry and can be used in developing of multilayer oil deposit. The concept of the invention is as follows: the method is characterized by identification of areas with increased thickness of sedimentary rocks during development of a deposit represented by the upper formation of sedimentary rocks of marine genesis and the lower carbonate formation. When such areas are available then the conclusion is made about available area of carbonate formation decompaction with increased oil flow rate. At that the increased thickness of sedimentary rocks coincides with the area of carbonate formation decompaction in plain view. The upper and lower formations are penetrated by injectors and a working agent is injected through them. The area of increase thickness in the upper formation sedimentary rocks and the decompaction area of the lower carbonate formation are penetrated by producers and the product is extracted through them.EFFECT: improving oil recovery of the deposit.1 tbl, 1 ex
