渝东南地区五峰组—龙马溪组一段发育了一套滞留盆地半深水—深水陆棚相暗色细粒页岩.通过岩石相精细研究,五峰组—龙一段纵向上划分出9种岩石相:富碳富硅富笔石页岩相﹑高碳高硅富笔石页岩相﹑中碳高硅高含笔石页岩相﹑低碳中硅含笔石纹层状页岩相﹑中碳中硅中含笔石页岩相﹑低碳低硅含笔石页岩相为6种主要岩石相,低碳低硅介壳灰岩相﹑低碳低硅白云质页岩相﹑低碳含灰泥质粉砂岩相为3种次要岩石相.富碳富硅富笔石页岩相和高碳高硅富笔石页岩相具有高有机碳含量﹑高孔隙度﹑高脆性﹑高含气性﹑微裂缝发育的特点,为最优岩石相,页岩气水平井在最优岩石相穿行时单井试气产量高.明确了不同区带水平井穿行最优靶窗,从而为更好地指导水平井穿行轨迹奠定基础.
