As a case of the Faulted Block W27 of WGT oilfield in the Huanghua depression,the flow units of heterogeneous reservoir in faulted blocks were pointed out.The sandbody distribution was made by the single sandbody correlation,and the single flow unit was identified after determination of fault sealing and sandbody architecture.The assembling analysis on the reservoir properties which were sensitive to the well performance was carried out,and the flow units were classified into four grades(grade E,G,M and P) and the model of the flow unit distribution was setup.The result indicated that the boundaries of the flow units were controlled by faults,sedimentary facies,and inner architecture of sandbody,and the quality of the flow units was controlled by sedimentology,structure,as well as property of reservoir fluids.It is important to optimize the plan of oilfield development and adjustment.
Key words： Flow unit; Sedimentary facies; Faults; WGT oilfield.
