摘　　要：通过对油藏相渗曲线的归一化处理,利用达西定律理论,建立采油指数与含水率的关系;再次通过油藏确定的单井经济极限采油量和油藏极限生产压差求出极限采油指数,从而得到极限含水率。并以低渗透油藏为实例验证了该方法的正确与适用性,说明该方法在对油田开发中确定极限含水率具有科学的指导意义。This paper presents the normalization processing of relative permeability curves from reservoirs, establishes the relafioriship between productivity index and water cut based on Darcy＇s law, and obtains the ultimate water cut from given well economic limit rate and reservoir limit producing pressure differential. The case study of low permeability reservoir demonstrates the validity and the practicability applied to determination of ultimate water cut in oilfield development.
