摘要
The Chang-ling Fault is a half graben rift which developed on the Paleozoic metamorphic basement.It is developed quite big thickness deep lacustrine facies black mudstone in Shahezi formation,with high abundance of organic matter,high thermal evolution degree,high hydrocarbon-generating intensity,thus it possess good basis of nature gas accumulation.Faulted period develop two suits of volcanic rocks,which Yingcheng formation distribut of large areas of burst facies and overflow facies volcanic rocks,the lithology are mainly of acid rhyolites,tuffs and volcanic breccias,with rich cavities and great reservoir physical properties.The eastern chang-ling fault develops two large ancient uplifts,with fault developing and good gas migration and accumulation.It have found three gas reservoirs and three gas bearing structures,that is a great favorable area of finding large-scale gas reservoirs.
