摘　　要：安塞油田长6油藏,受储层非均质性影响较强。随着开发时间的延长,油藏平面及剖面上的矛盾日益突出,注入水单向或多向突进导致油井含水上升速度较快,制约了油藏的整体开发效果。近年通过实施注水井深部调剖措施,封堵优势见水方向,扩大水驱波及体积,提高水驱动用程度,达到稳油控水的目的,对油藏的稳产起到了较好的作用。本文重点对历年的注水井深部化学调剖效果进行了分析,并对该技术措施在油藏开发中的适应性进行了评价,为今后同类型油藏的开发调整提供了方向。Chang 6reservoir,which is controled by heterogeneity,is the main reservoir of Ansai Oilfield.With the development of waterflooding,the problem of flat and vertical in the reservoir becomes more complex：because of unidirectional or multidirectional injected water rushing,the well-water is rising rapidly.In recent years,through the injection well deep profile control,pluging the advantage injected water direction,expanding sweeping volume,and improving the degree of water flooding.The paper mainly analyzed the effect of the injection well deep profile control in Chang 6reservoir,and then evaluating its applicability,which provides a practical method for the same type reservoirs.
