利用生产数据计算油藏相对渗透率曲线方法

Method of calculating relative permeability curve by production data

提出了一种应用生产数据含水率计算油藏相对渗透率的方法。该方法反映了实际油田的生产动态, 这样获得的曲线具有一定的代表性。这种方法能克服实验测试带来的局限性, 不仅能获得相对渗透率比值, 还能获得相对渗透率值。在此基础上, 还可以对油田的开发指标进行预测, 对开发效果进行评价。

This paper presents a method of calculating relative permeability in an oil reservoir with the help of production data-water cut.The method can reflect the actual production performance of oil field,thus the obtained curve can have certain representativeness. In addition,the method can not only overcome the limit resulted from pilot test,but also gain the ratio of relative permeability and its value.On the basis of the above, it can also predict oilfield development indexes and evaluate the development effects.
