摘要
通过对铁法矿区矿井实际资料的研究,依据围岩节理及煤层裂隙的宏观、微观统计分析,探讨了煤储层孔裂隙的发育特征,对该区储层渗透率进行了预测。认为区内褶曲发育,褶皱轴部地带为裂隙发育带,煤层裂隙发育,连通性好,具备储层渗透性好的优势;受区域构造应力场控制,裂隙发育表现出明显的方向性,主裂隙发育的NW方向为渗透性优势方位。
Through the studies on mine factual information of Tiefa mining area, based on macroscopic and microscopic statistics and analyses of adjoining rock joints and coal seam fissures, discussed development features of coal reservoir pores and fissures, and then predicted reservoir permeability in the area. Considered that well-developed folds in the area, thus the axial zones of folds must be well-developed fissure zones, good connectivity make the reservoir provided with good permeability; since controlled by regional tectonic stress field, the development of fissures shows obvious directional property, the main fissure developing NW direction is also the permeability superiority trend.
