研究小层剩余油的传统方法是根据静、动态资料确定目前剩余油的饱和应并分配到小层,从而从宏观上确定整个油区的剩余油挖潜区。文中应用盈亏平衡的原理,从技术经济的角度对剩余油饱和度低的抵效油井进行了微观分析,由此进一步指出剩余油分布的范围和层位,这同样可为油田开发决策提供依据。

The conventional way to study minor-layer residual oil is to calculate the present saturability of residual oil according to the static and dynamic data and allocate it to the minor layers so as to determin the potential residual oil regions in the whole oil area macroscopically. In this paper, the principle of balance of profit and loss is applied to analyse the low-efficient oil wells with low residual oil saturability microscopically from the technical economic angle, and the range and horizon of distribution for residual oil is pointed out further. This also provides basis for the decision of oil field development.
