Research Of Micro Structure And Characteristics Of Flow Unit For Major Reservoir In Shu 32 Block

Elm forest oil field is Extra low permeability oil field,regional tectonic belonging to The eastern slope of three in the song of The central depression in Songliao Basin.The main mining is Fuyang oil layer, reservoir drainage difficulty.Water flooding mechanism is complex.Shu 32 block is located in the east of Elm forest Oil Field, belongs to the three class block. Exploitation of Fuyang oil layer. Since the development since the 1992, exposed the problem is Flooding is difficult, Interlayer and plane contradiction Prominent and Production decline rate. Part of well group, the speed of water cut increases. In view of the problem, conduct injection well fracturing stimulation and Local wells injection-production system adjustment test, but the effect is not obvious. In order to improve the understanding of reservoir geology, to solve the problem that exists in development, to carry out the fine reservoir description in the Shu 32 block, Through the project research, on the formation of fine division and correlation, clear genetic type of sand body and heterogeneous characteristics. Identify the main oil-bearing reservoir types and distribution and The main reservoir flow unit division final accurate. By means of numerical simulation, study on the distribution of residual oil in it. Guide the development of adjustment. Improve economic surplus reserves producing degree. The project technology will provide reliable geological basis for oilfield development, To solve the existing problems in the development of, To improve the economic surplus reserves of effective use of the degree of objective. Important contributions to The Elm forest company production and sustainable development.
