The Reservoir Geological Research Of Ng–Es1 Of Shang Er Area Of Shangdian Oilfield In Dongying Depression

The fine study of reservoir geology is an important work in the high water cut stage or the late development stage.It is the basis of all kinds of development adjustment plan and decision making.The main research area Shangdian oilfield has entered in high water cut stage,strengthen reservoir description,through fine geologic study,from the formation,structure,sedimentation and reservoir heterogeneity research in all,to solve the main problems and contradictions which restrict the development of oil and gas in this area,in order to promote sustainable oilfield reasonable and efficient development and operation.The main research content is fine analysis of Ng –Es1 formation of oil and gas reservoir geological conditions,re evaluation of the OOIP of the oil and GOIP of gas reservoir.The main research content is carried out by means of fine stratigraphic classification and correlation,to further strengthen the implementation of micro-structural characteristic analysis,which is controlling remaining oil,sedimentary facies and sedimentary microfacies,reservoir heterogeneity,the clear research section of oil and gas reservoir geological conditions,in addition to the fine reservoir anatomy(dynamic and static),combined with drilling,logging,re evaluation of the OOIP of the oil and GOIP of gas reservoir.In this paper research has important significance for the development of oil and gas fields in the area,To lay a good foundation for the sustainable and efficient operation of the late oil field.
