本文根据8口取心井的岩心资料重新对油田水顶(油水过渡段)进行划分,得出用岩心资料划分的油水过渡段的厚度,比用电测和试油资料确定的油水过渡段的厚度增加36.6～68.6ｍ,含油饱和度为30～40%,从而为油田增加了新的储量.并据此提出影响油水过渡段增厚的原因,指出电测和试油资料确定油水过渡段的不足和影响因素.

Based on the core data from 8 core hole,the water top (oil-water transitional belt)in the two oilfields is redivided.It is concluded that its thickness range reaches 36.6-68.6m more than that acquired by the data of electric loggings and oil testings.Therefore,it means the oil saturation being 30～40%,an increase in oil/gas reserves for the oilfields.The study also discusses about the cause for the larger thickness of this transitional belt,and the inadequacy and affects of the determination with the data of electric logging andpotential tests.
