摘　　要：塔河奥陶系碳酸盐岩油藏属于缝洞型油藏,不同类型的缝洞单元由于储集体规模和水体的发育程度不同造成天然驱动能量具有较大差异,部分油井天然能量严重不足、产量递减快,采收率低。注水替油作为塔河碳酸盐岩油藏一种新型开采方式,已经取得了较好的效果。针对注水替油后期,油水界面上升导致含水上升快的问题,对衰竭式开发、单纯注水替油机抽开发以及采用机抽-深抽开发等不同方式的效果进行对比研究,明确了采用加大泵挂深度可以提高油藏采收率,改善开发效果,从而为矿场实施提供依据。The Ordovician carbonate rock reservoirs in Tahe belong to fractured-vuggy ones,the differences of reservoir volume and aquifer volume cause a big difference in natural drive energy in different types of fractured-vuggy units.Some oil wells lack natural energy,which leads to rapid decline of production and the low recovery.Water injection substituting for oil,as a new approach to exploit the carbonate rock reservoirs in Tahe Oilfield,has achieved good results.In view of the fast increased water cut caused by the rising of WOC in the late period of flooding,through comparative study on the effects of depletion drive,flooding and artificial lift,increase of the pump setting depth shows that increase of the pump setting depth can enhance the reservoir recovery and improve the development,so as to provide the basic concept for field operation.
