煤储层渗透率模拟——以沁水盆地太原组为例

Permeability Simulation of Coal Reservoir:Taking Taiyuan Formation Coal-Bed in Qinshui Basin as an Example

渗透率是评价煤储层渗透性的重要参数,通过对割理、有效应力、埋深等煤储层渗透率影响因素的数值模拟研究,结果表明,割理的发育程度决定了煤储层的渗透性,割理的闭合、开启程度又受到应力场的控制。

Permeability parameter is very important in evaluating the permeability of coal reservoir.This paper researches on the numerical simulation of coal-bed cleat, effective stress,depth that affects the permeability of coal reservoir.The results show that develoment of clrat determines the permeability of coal reservoir,while the opening and closing of cleat relies on the stress field.
