摘　　要：针对目前单层剩余油分布研究的局限性,基于油藏工程理论建立了单层规模的剩余油饱和度定量预测方法。运用物质平衡原理计算单层井点压差,而动态劈分法的运用克服了一般劈分法预测单层剩余油精度低的局限性;同时利用单井含水率校正分层含水率,使得计算结果更加合理和准确。与数值模拟方法相比,占用内存小、运算速度快、计算精度高,具有极大的矿场应用价值。In view of the limitations of remaining oil distribution in the single layer,a quantitative prediction methodis established for single layer based on the study of reservoir engineering theory. The using of the material balanceprinciple can calculate accurately the pressure of each well in the single layer,contrasting to the general splittingmethods,the application of dynamic splitting method can overcome the low precision. It makes the results morereasonable by the water cut of single well to adjust the stratified water cut. Compared with the numerical model,thesoftware of the method runs more quickly and requires less built-in storage and capacity. Moreover,the calculationresults prove in this paper that the single sand-body of the remaining quantitative method is feasible.
