摘要
为了评价油藏水驱开发效果,根据Welge方程以及油水两相相对渗透率测试数据,建立了快速绘制含水率、驱油效率与注入孔隙体积倍数关系曲线的方法。应用实例表明,该方法为评价油藏开发潜力提供了一种新的手段,同时可有效弥补室内实验测试过程中带来的误差,对于油藏动态分析、产量预测等方面具有重要意义。
In order to evaluate the developed effects of the oil reservoir water flooding, according to Welge Equa- tion and oil-water relative permeability test data, the method was established for quickly drawing the relationship curves between the water cut, oil displaced efficiency and injection pore volume. The case study shows that it can provide a new way to evaluate the potential of the reservoir development, and moreover can effectively compensate the error caused in the process of the indoor experiment and test, thus it possesses important significances for the dynamic analysis, production prediction etc. of the oil reservoirs.
