贵州毕节煤田可乐矿区M18煤储层地质特征研究
|
摘要
通过对毕节煤田可乐矿区M18煤岩煤质特征、煤储层压力及温度、煤层渗透性、煤层等温吸附特征、煤层含气性的研究,结果表明:区内18号煤层在西部为贫煤,中东部为无烟煤,为低渗透率煤储层,储层压力系数为0.6—0.9,属于欠压地层。煤层平均含气量为14.17m3/t,含气量较高。
By the study of Bijie coal Cola mine, Ce Le mining area M18 coal quality characteristics, coal storage layer pressure and temperature, coal seam permeability, coal isothermal adsorption characteristics and coalbed gas. The results show that: 18 coal seams in the west is lean, the middle- east is anthracite with low permeability, the reservoir pressure coeffi cient is 0.6~ 0.9, belongs to the under pressure stratum. The average gas content in coal seam is 14.17m~3 / T, and the gas content is high.
