摘要
通过对川西地区典型油气田上沙溪庙组(J_2s)成岩作用的研究,确立了该区储层存在四种不同的成岩矿物相带:绿泥石-沸石相带、高岭石相带、碳酸盐相带及石英次生加大相带;探讨了成岩矿物相带与油气的关系,指出绿泥石-沸石成岩矿物相带是本区有利的成岩矿物组合相带。
Based on study of diagenesis of the Upper Shaximiao Formation(J2s)in the typical gas field in Chuanxi region, this paper identifies four different facies tracts of diagenet-ic minerals in the reservoirs including chlorite ?zeolite < kaolinite, carbonate and quartz secondary outgrowth. It discusses the relationship between facies tract of diagenet-ic minerals and hydrocarbons and points out that the chlorite - zeolite facies tract is favorable in this area.
