摘　　要：油田的合理配注，油藏动态分析及分层动用状况分析等都需要油田分层产量数据。为寻找一种简便、合理和科学的动态数据劈分方法，在地层系数法的基础上，考虑油水相对渗透率随含水率变化的特性，应用各层系相对渗透率资料，推导得到了一种油井分层产量劈分模型，称之为改进的地层系数法。应用该方法劈分某区块动态数据，并利用数值模拟结果对劈分结果进行验证，结果表明该方法劈分精度高，劈分结果合理、可靠，能够满足实际应用的需要。The production data of the seperated layers in an oilfield are needed for the rational injection distribu- tion, reservoir＇s dynamic analyses, developed conditions of the seperated layers and so on. In order to find out a simple, reasonable and scientific cleaving method for the performance data, on the basis of KH method and consid- ering the features of the relative permeability changes of the oil and water with the water cut, a new production-clea- ving model for the seperated layers is derived, that is named improved KH method. With the help of the above method~ the dynamic data in a certain block are cleaved1 and furthermore the results are verified by the results of numerical simulation is tested. The contrasted results show that the new method has won the following advantages： high resolution, reasonable and credible achievements, so it can meet the requirements of the actual application.
