摘　　要：库姆克尔油田为高孔高渗大型海外油田,目前已经进入了特高含水开发后期,地层压力保持程度低,产量递减大,需要采用合理地层压力来保持产量稳定。通过对比最小流压法、静水柱压力法、低渗透性油藏特征法、原油粘度法、最小自然递减法、地层压力与累积注采比关系法等多种方法基础上提出了采用采液强度法预测开发后期合理地层压力。Kumkol South oilfield is a reservoir with high porosity and permeability in Kazakhstan. Production per-formance is in the latest development stage,so the oil field requires reasonable formation pressure to keep pro-duction steady. Through comparing methods like minimum flow pressure method,and static water pressure meth-od,and low penetration reservoir features method,and crude oil viscosity degrees method,and minimum naturaldecline method,and relationship of formation pressure and cumulative injection- production ratio method,itturned out that all these methods are not suit for high water cut reservoir. The new method which uses the relativepermeability curve,fluid producing intensity and water cut is proposed to forecast the reasonable formation pres-sure of the oilfield development in the latest stage.
