| 摘 要： | 以四川盆地南部嘉陵江组钻探和开发成果为基础,分析了嘉陵江组气藏的烃源、储层、盖层和圈闭条件等成藏要素,研究认为烃源断层是二叠系和更深层烃源层中天然气进入嘉陵江组的重要输导条件,烃源断层不发育的构造因为嘉陵江组自身烃源条件差难以形成气藏.嘉陵江组天然气藏为依靠喜马拉雅期断层输导的远源成藏模式,成藏控制因素可概括为:烃源断层控制了气源;沉积成岩相带、中三叠世末期古隆起剥蚀作用和裂缝发育控制了储层分布、储层渗透性与连通范围;古隆起剥蚀作用和断层作用同样控制了圈闭的保存条件.

| Abstract: | Based on the data of drilling and development of Lower Triassic Jialingjiang Formation in the south of Sichuan Basin,this paper analyses the factors of hydrocarbon accumulation,such as hydrocarbon source,reservoirs,cap rocks and traps.It reveals that the gas in the reservoir of the Jialingjiang Formation originates from Permian and/or the lower strata through the fault with hydrocarbon source during Himalayan Movement and there are no gas reservoirs in the structures without developed faults with hydrocarbo... |
