The Sedimentary Microfacies And Residual Oil Research Of The FUYU Reservoirs In ChaoNan-45Development Area

The research object of this page is the Fuyu reservoirs in Chaoyanggou developmentarea.Basing on the application of high resolution sequence stratigraphy and sedimentarytheory,stratigraphic multi-level base cycles classification and correlation and theestablishment stratigraphic framework has been done. In the interval of interest of theresearch areas. On the basis of fully using the core data and database, the static field data, thereservoir heterogeneity remaining oil distribution of. the interval of interest are studied.Research areas have been developed over nearly30years. It has entered the middle-laterstage of development,. The research is of vital importance. This research in the study area isdone.The17layer segment for46time unit is divided in vertical in the Fuyu reservoirs, eachtime unit for a short-term base-level cyclic sequences, corresponding to a river. This paper isbased The short-term base-level cyclic sequences sedimentary microfacies in the Fuyureservoirs, emphasise on the reservoirs, namely distributary channel sand reservoir. Throughlogging microfacies recognition,the combination of plane face,46short-term base-level cyclicsequences of sedimentary microfacies are made. And with FⅠ22FⅠ52FⅠ3, reservoir, asan example,the study of reservoir in different parameters of sedimentary microfaciescontrolling exhibition and distribution, and the analysis of distribution of reservoirheterogeneity is made.On the basis of study area, the study of remaining oil distribution,summarized the research area of six kinds of remaining oil distribution types and distributionof residual oil.
