Research Of Sedimentary Microfacies Of Reservoir In 48 Qian Area

Research of sedimentary microfacies is a very important basic work in process of oilfield development. The planar distribution characteristics of sedimentary microfacies of FY reservoir in SongLiao basin which the character is very complex are studied systematically by this paper. Through the accurate correlation. The original 12 sedimentary layers are broken into 25 sedimentary units, and the reservoir quality are evaluated also. Based on the features of sand body development and oil-bearing, 25 sedimentary units are sorted out 4 types of reservoir. On the basis of these research, this paper also discusses the water fluid drive development of FY reservoir. These resultes provide an important basic for the research of architecture inside sand body and futrue development.
