Study On Remaining Oil Distribution Patterns In Ma 19 Area Of West Sag In LiaoHe Depression

Ma 19 area of Dongying group of oil area is 10.3km2, the geological reserves is 763×104t, rich in crude oil reserves, produc tion level is low, with a good material base. The area in 1970 s put into development, has been developed for nearly 40 years, the current production rate is only 0.3%, the oil well utilization rate is 20.5%, in the low speed development. In recent years, in the implementation of the 19 Ma well area local tectonic position side drilling, adjusting and mending layer and water layer, dry layer, unexplain layer awareness of potential measures to see good increased oil effect confirmed the well area still have great potential for development, carry out systematic geological research, can further expand the practical results and used to guide the work of the development of oil fields to increase oil production to.Application of 3D seismic data, drilling, logging, well logging, oil production and other data, to carry out research on the geological characteristics, reservoir, oil gas water distribution.The research of geological characteristics including research characteristics of sedimentary characteristics and reservoir formation characteristics. The basic principle of reservoir inversion using wave impedance inversion, clearly reflects the change of different lithology in space. Study on reservoir characteristics including reservoir fluid characteristics, oil gas water distribution research, reserves calculation, 3D geological model. Through the work of comprehensive geological study, using the eclipse numerical simulation software, the numerical simulation of distribution of remaining oil in the study area, the residual oil distribution are determined.
