Wang Ji and its surrounding areas are located in the middle of the northern slope of Biyang Depression,where faults are well developed.Reservoirs are controlled by multiple provenances,and sedimentary facies zones change rapidly.The plane distribution of sand body is complex,and the matching relationship between sand body and structure is not clear.As a result, more and more concealed reservoirs are available for exploration and development. Oil and gas exploration has shifted from simple structural reservoirs to concealed fault-lithologic and lithologic reservoirs.On the basis of fine stratigraphic correlation,this paper studies reservoir distribution characteristics and subdivides single sand body vertically.Laterally,the distribution boundary of effective reservoirs and lithologic sealing dry zones is described in detail,and the favorable areas for the development of fault-lithologic traps are sorted out layer by layer.It lays a foundation for the exploration of lithologic and composite reservoirs.
