胡5块严重非均质极复杂断块油藏数值模拟研究

Numerical Simulation of Serious Heterogeneous and Very Complicated Fault Block Reservoirs in Block Hu 5

针对油藏存在的问题,在精细地质研究的基础上,根据渗流等效的原则,进行了网格粗化,应用数值模拟软件对严重非均质的极复杂断块——胡5断块进行了油藏数值模拟研究。通过模拟研究,得出了该断块的剩余油饱和度分布,对比分析了不同方式下的4个开发方案,推荐出了指导该油藏下一步生产的综合调整方案。

In consideration of the problems existed in the reservoir, the network is arranged initially on the basis of geologic study in combination with a percolation and equivalence principle, a numerical simulation software is used to simulate the reservoirs in Block Hu 5, which is a very complicated fault block with serious heterogeneity. Through simulation study, the distribution of residual oil saturation is obtained, 4 different development programs are compared, an integral adjustment scheme is recommended for guiding the production in the future.
