摘要
华蓥山构造带北端已近川东石炭系残存区西缘，初探失利较多。本文经与川东石炭系气区对比后，认为华蓥山构造带北端与川东石炭系气区其它地区相似，具有气富集的因素，残余厚度较大，准同生白云岩发育，储层较好，有较多有利气聚集的低潜圈闭，文章对这些低潜圈闭进行分类后分别作了评述。
The bad results have been experiencecd in the early exploration in the northern end of Huaying Mountain Belt which is near to the western margin of residual carboniferous of Chuandong,Cowmpared with gas-bearing area in Carboniferous of Chuandong,it is shown that the northern end of Huaying Mountain structural belt is similar to the other parts of gas-bearing area in Carboniferous Chuandong, and characterized by gas rich accumulation,thicker residual formation,developed penecontemporaneous chalk rock,well-developed reservoir,and has more low potential traps favorable for gas accumulation, These traps are sorted and discussed in the paper.
