摘要
本文根据大量的煤田地质勘探资料及最近取得的煤层气勘探井的成果,系统地分析研究了该矿区煤储层的物性特征,并对其地质控制因素进行了探讨。该矿区主力煤层厚度大且稳定,热演化程度高,含气量高,渗透性较好;构造活动史、煤层埋深、热演化程度及水文地质特征是煤层气富集的主要控制因素,并决定其物性特征,进而对其可抽性产生影响。
Based on large quantity of information collected during coal exploration and recently drilled CBM wells, systematic study has been carried out on physical characteristics of coal reservoir in this mine area, and discussion has been made on corresponding geological control factors. The main coal seams are thick and regu- lar. The degree of thermal evolution and the gas content are high, and permeability is good. The tectonic movement history, the depth of coal seams, thermal evolution degree and hydro-geological conditions are major control factors for CBM enrichment, and determine the physical Characteristics and influence the gas productivity.
