摘要
在恩洪煤层气勘查中,为攻破难关,根据地质特点、诸多物探方法中,首选二维地震勘探,在煤层埋深大于300m以上的未经勘探区,进行区域性了解。查清区内地层发育情况,煤层埋藏深度、厚度及变化情况。了解区内断层及其性质,对主要煤层的展布进行追踪,经过勘探结果,在高原山区利用地震勘探取得了较好的地质效果。
According to the geological characteristics and in order to overcome the difficulties, in many exploration methods we first select the 2D seismic exploration for the regional reconniassance of an unexplored area with coal bed depth more than 300m, to study the development of strata in this area ,depth, thickness and their changes of the coal beds, the faults and their qalities, to trace the distribution of main coal beds. In the plateau mountainous area, the seismic exploration has got good geological effects.
