摘要
针对沁水盆地煤层气井网布置采用的主要是菱形等间距布置法,未考虑地质构造对煤层气井控制面积的影响情况,以地下水活动较弱,对煤层气富集保存有利,产出过程影响较小的沁水盆地中、南部的晋城矿区西部为例,分析了在不同构造部位,煤层气井初始产气时间、平均产水量、累计产气量、产气高峰的时间差异及造成差异的原因,并提出了构造特征与井网布置的关系.
At present, in Qinshui basin, coal-bed methane wells networks arrangement mainly used by equidistant diamond layout, this method has not considered the influences between geological character and controlling area of coal-bed methane wells. In light of this, chosed the area that its groundwater activities was weak, it was favored to the enrichment and preservation of coal-bed methane, its influence was small to explore coal-bed methane, this area live in the western Jincheng diggings in the southern Qinshui basin. In different geological positions, discussed systemically the differences of time about gas production, water production and cumulative gas production of coalbed methane wells and the reasons for the disparity, and pointed out that the relations between the geological structure and wells arrangement.
