利用生产数据求取相对渗透率以及预测油田动态的一种方法

A TECHNIQUE OF ESTIMATING RELATIVE PERMEABILITY CURE FROM PRODUCTION DATA AND THE PREDICTION OF THE RESERVOIR PERFORMANCE

本文提出了一种运用生产数据求取相对渗透率的方法。该方法反映了实际油层生产动态,可以认为求出的曲线是有代表性的。这种方法能克服实验室测试带来的局限性,不仅能求出相对渗透率比值,而且能求得相对渗透率值。在此基础之上,可以对油田的开发指标进行预测,对开发效果进行评价。

A technique of estimating relative permeability from production data is presented in this paper. The relative permeability curves thus obtained can discribe reservoir performance more better because both the results of field production and laboratory displacement experiment are considered, This method can overcome the limitations of laboratory determination. Both the ratio of relative permeability and the numerical value of relative permeability can be obtained by this technique. It can be used to predict the performance of the oil reservoir as exhibited by the example presented.
