“川西北龙门山逆掩断层带有印支和喜山期的巨大推覆体存在;四川地质构造盆地向西北方向延伸了数十公里;而且,在推覆体基盘和推覆片中,有可供钻探的圈闭构造”。这一重大的勘探成果,是四川石油管理局地质调查处在1987年12月下旬召开的地震勘探汇报会上披露的。这是四川探区地震勘探工作在川西龙门山地区继70年代发现中坝气田之后取得的又一重要进展。
“There is a tremendous thrust nappe in the thrust belt of the Longmen Shan in the northwestern Sichuan Province with the Indo-China and the Himalayan period. The Sichuan geological structure basin extends tens of kilometers to the northwest, and in the thrust plate and the nappe sheet, Trap structure available for drilling. ” This significant exploration result was disclosed by the Geological Survey of Sichuan Petroleum Administration at the seismic exploration briefing meeting held in late December 1987. This is another important progress made by the seismic exploration work of the Sichuan Exploration Area in the Longmenshan area in western Sichuan since the discovery of the Zhongba gas field in the 1970s.
