摘要
利用温泉井构造带嘉陵江组勘探和研究成果,对嘉陵江组气藏成藏条件开展了详细研究。分析认为:嘉陵江组天然气是混源气,烃源条件充足;嘉二储层发育,是区内嘉陵江组主要储层发育段和含气层段;嘉二顶构造完整,圈闭面积大,构造带嘉二可能整体含气;膏岩盖层发育,对气藏的保存有利。储集条件是影响嘉陵江组气藏成藏的关键因素。
Based on the exploration and achievement in Jialingjiang Formation of Wenquanjing structural belts,the reservoir-forming condition in Jialingjiang Formation is carefully studied.By the analysis,it is considered that the gas in Jialingjiang Formation is composed of the mixed source with abundant source rock;Jialingjiang 2 Member is the primary development formation and gas-bearing interval;Jialingjiang 2 member with the integrated top structure and with the great acreage of traps may bear gas in the whole structural belts;it is favorable for the gas reservoir to reserve due to the development of gypsolyte caprock.Consequently,reservoir conditions are key factors which influences Jialingjiang Formation reservoir to form.
