多层裂缝性气藏越流问题的数值模拟研究

Numerical Simulation Study of Over-Flow Problem about Multi-Layer Fractured Gas Reservoir

本文在建立多层双重介质天然气藏越流问题数学模型的基础上,利用求解差分方程的最佳点超松弛叠代法,获得了它的数值解,同时还对此类油气藏的压力特征作了分析,并指出了越流研究对油气藏勘探的指导意义。

Based on Setting up the mathematical model of over-flow problem about multi-layer double medi- um natural gas reservoir, its numerical solution is obtained by use of the override iteration for solving the optimum point of the difference equation. At the same time, the pressure behavior of oil and gas reservoirs of this type is analyzed and it is pointed out that the over-flow study has a guide significance for oil and gas rescrvoir exploration.
