摘要:
利用有机岩石学、干酪根碳同位素、X?射线衍射、场发射扫描电镜等实验测试资料,阐述了川东南—黔西北地区上二叠统龙潭组海陆过渡相页岩烃源岩品质、储层发育及含气性特征,并探讨了孔隙类型和含气性的主控因素。研究表明,川东南—黔西北地区龙潭组泥页岩总有机质丰度高(TOC值平均为3.50%)、热演化程度高(RO值平均为2.23%),有机显微组分以镜质体为主,惰质体次之,以Ⅲ型干酪根为主,是一套优质气源岩。页岩储层具有较好的物性(孔隙度平均为5.56%),孔隙类型以黏土矿物孔为主,其中伊/蒙混层间微孔隙较发育,主要为介孔—微孔,有机质孔基本不发育。泥页岩吸附气含量和总含气量变化较大。有机显微组分是控制龙潭组高成熟富有机质页岩有机孔隙发育的首要因素,有机质丰度是控制页岩吸附能力和含气性的重要因素。
