摘要
采用煤岩学方法研究煤储层特性，可直接观察孔裂隙的分布、形态、数量、充填状态等特征，有利于查明显微孔裂隙成因、影响因素及演化规律。将显微孔隙分为生物成因孔和非生物成因孔；显微裂隙划分出内生裂隙、继承性裂隙、层面裂隙和构造裂隙；分别研究了各类显微孔裂隙在煤储层中的分布、随煤化作用的演化规律及其与渗透率的关系，并取得了良好的效果。
To study coal reservoir nature using coal petrological approache is characteristic with investigating occurrence,shape,quantity,filling of micropore fracture system directly.This approach is useful to find out the origin,evaluation law and its influence factors of microfracture.Micropore is divided into phyteral cell remaining pore,matrix pore and new forming pore during coalification.The microfracture system consists of butt cleat,face cleat,inherited butt cleat and joint.In this paper,the distribution,evaluation law with coalification of microfracture and their relation to coal permeability have been researched,and some new results have been obtained.
