| 摘 要： | 从油气的烃源条件、储集条件、保存条件及成藏组合方面入手,结合构造史以及岩心、地震及钻井等资料,对川西回龙地区沙溪庙组气藏的成藏主控因素进行分析。结果证实,该地区沙溪庙组气藏具有良好的生、储、盖组合条件,气藏成藏主控因素主要为低阻抗的孔隙性砂体、边界气源断层以及有效的圈闭。典型砂体成藏剖析揭示,区内存在3种典型的成藏组合模式,但受圈闭限制,气藏成藏规模有限。

| Abstract: | Based on the studies of source rock,storage,preservation and accumulation conditions for hydrocarbon,combined with tectonic history,core,seismic and drilling data,the main controlling factors for gas accumulation in Shaximiao Formation in Huilong area of the Western Sichuan Depression were analyzed.It was concluded that the study area was favorable for hydrocarbon generation,storage and capping.The main controlling factors included porous sand body with low impedance,boundary fault and effective trap.Typica... |
