复杂断块气藏模拟网格设计方法

Grid Design Method for Simulating Complex Fault—Block Gas Reservoirs

本文针对S_4～(3+4)复杂断块气藏实际,提出了按断块设计网格的方法。即根据各断块的具体情况,既独立又相互有机联系地各自设计自己的网格,使网格数和计算工作量都大为减少。S_4～(3+4)气藏的数值模拟实算表明。按断块设计网格不失为一种经济、有效的适用模拟技术。

Countering the practice of complex fault-block gas reservoir S_4~3+4,a method to design grids ac- cording to fault-blocks is presented in this paper. It means to design respectively individual grid inde- pendently as well as interrelatedly based on the concrete conditions of various fault-block ,making the amounts of grids and the calculation works greatly reduced. The culculation of numerical simulation of the gas reservoir S_4~3+4 indicates that it is a economic,effective and applicable simulation technique,ac- cording to the fault-block to design grids.
