Vertical variation of rocks and minerals in Wufeng-Longmaxi formations in Fuling shale gas field, Sichuan Basin: A case study of well JYA

  • 摘要: 涪陵页岩气田是我国首个实现商业开发的大型页岩气田。通过对涪陵焦石坝区块JYA井五峰组-龙马溪组龙一段页岩开展岩石薄片和氩离子抛光扫描电镜观察,并结合全岩黏土X衍射、有机碳含量等分析测试,探究了该气田五峰组-龙马溪组龙一段页岩纵向上的矿物成分及含量的变化特征,明确了该套页岩主要成分为石英和黏土矿物,其次为长石和碳酸盐,以及少量的黄铁矿;其中石英和黏土矿物达70%以上,自下而上石英、长石及黄铁矿含量逐渐减少,黏土矿物含量逐渐增加。结合页岩矿物纵向上的差异性变化,探讨了其对页岩储集性、含气性和可压性的影响,明确了纵向上随着生物成因硅质含量增加,黏土矿物含量的减少,页岩自上而下呈现出有机质含量增加,有机质孔发育,页岩储集性能变好,页岩含气量增加的趋势;同时随着脆性矿物含量的增加,页岩的可压性也逐渐增强。
