The Qinjiatun Oilfield,is located in the southern Songliao Basin and eastern slope of the Lishu Fault.Plane and vertical heterogeneity,low recovery,high cut rising rate and natural decline rate are verified before water injection development.Based on the evaluation of waterflood development,dynamic analysis,calculation reserves and remaining reserves,determining the reperforate,fracture and injection layer and greatly improving development effect to reach the purpose of stabilized production.%秦家屯油田S142区块位于松辽盆地南部东南隆起区梨树断陷东北部,投入注水开发以来,目前出现平面、纵向非均质性较强,采出程度低,采油速度慢,含水上升率较大,自然递减较大,油井受效不均一等一系列问题,文章通过注水开发评价、动态分析、储量复算、剩余储量复算等分析,确定通过补孔、压裂、完善注采层位等手段,达到改善水驱开发效果,提高油田采收率的目的,具有重要的经济意义。
