摘　　要：高7断块油藏是高集油田主力区块之一,2套含油层系阜宁组阜二段2、3油层组(E1f22、E1f32)共划分9个单砂体,砂体间动用程度差异大,纵向平面水驱不均匀,含水上升快,注采矛盾突出。为抑制含水上升过快,需要开展深部调驱作业。为此采用流线模拟法追踪流线轨迹来模拟注采井间各小层流线分布,判别注采井间各层系连通性。模拟计算结果表明E1f3-12、E1f3-52小层流线分布密集,为主力开发层系,高7-13井、高7-14井和高7-5井三口井周围流线共聚度大,油水井间连通性好,为区块调驱选井选层提供依据。The Fault Block Gao 7was one of the main production blocks of Gaoji Oilfield.There were two sets of oil-bearing series named E1f22 and E1f32,which were subdivided into 9single sand bodies in total.The producing degree between sand bodies varied dramatically,and vertically the waterline moved forward unevenly on the plane.So it resulted in fast water breakthrough and serious contradiction between injection-production wells.Therefore,deep profile control technology was used to solve the problem of rapid rising of water content.Therefore streamline simulation methods of tracking streamline trajectory were adopted to simulate the flow line distribution in injection-production between the wells,and determine the connectivity of each stratum between injection-production wells.The simulation results indicate that the flow line distribution of the sublayer is close in E1f3-12,E1f3-52,which are the main development strata.In Wells Gao7-13,Gao7-14 and Gao7-5,the streamlines are highly concentrated with good interwell connectivity,it provides basis for block and layer selection for profile control.
