在煤层气开发过程中,煤层裂缝渗透率的分布规律对于后期的煤层压裂改造至关重要,裂缝开度是计算裂缝孔隙度、渗透率的基础,是联系应力、应变与裂缝孔隙度、渗透率的纽带。通过对柿庄北3#煤层裂缝参数的数值模拟研究并进行结果验证,从而为深煤层煤层气开采提供有效的理论依据。 During the process of CBM development, the distribution law of coal seam fracture permeability is very important for the later coal seam fracturing reformation. The fracture opening is the basis for calculating the fracture porosity and permeability, and is the relationship between the contact stress, strain and fracture porosity, Rate of the link. Through the numerical simulation research on the fracture parameters of No. 3 seam in Shizhuangbei and the result verification, it provides an effective theoretical basis for deep seam coalbed methane exploitation.
