煤割理压缩实验及渗透率数值模拟

Compress experiment of coal cleat and mathematical simulation of coal reservoir permeability

基于煤割理压缩实验 ,建立了应力与割理宽度之间的数学模型 .通过对山西沁水盆地中～南部煤储层现代地应力的数值模拟 ,借鉴裂隙岩体渗透率张量公式 ,结合浅部煤割理观测资料 。

Based on compress experiment of coal cleat, mathematical model between stress and cleat width was erected. Permeability of the deep seated coal reservoirs in middle to south of Qinshui basin of Shanxi Province was predicted by means of simulating modern stress, using for reference the permeability tensor formula of fracture rock and integrating observation data of the shallow seated coal cleat.
