摘要
DH-1煤层气参数井位于鸡西矿区东海矿18勘探线80-10孔南150m,该矿区地层构造简单,煤层较厚,含气量高,是鸡西煤田煤层气勘探的首选目标区。主要阐述了采好煤心的技术措施,通过精心施工和技术措施的运用,煤样采取率高,质量好,保证了参数井对煤层取样要求。
Coalbed gas parameter DH-1 bore hole locate in DongHai coal mine of JiXi mining area, 150 meter to the south of 80-10 bore hole in 18th exploratory line. In the mining area, structure of strata is simpleness,coal seams thicker,high quality coalbed gas, preferred target area of coalbed gas Exploration in JiXi coalfield.mainly recounted gain coal core technique measure, through drilling and use technique measure carefully, get high factor of coal sample, quality better, guarantee that take demand coal sample in the parameter hole.
