摘要: 上扬子地区广泛发育多套烃源岩,其中渝东南地区五峰组—龙马溪组具有有机质页岩厚度大、TOC丰度高、有机质成熟度适中等特点,整体具备页岩气发育的气源条件;但各钻井含气性差异显著,可见区域构造对页岩气的后期保存存在重要影响。以渝东南地区为例,通过野外地质调查、岩心观测、含气性分析等手段,研究区域构造分布对页岩气赋存条件的影响,并认为:渝东南地区主要断裂均为逆断裂,且靠近褶皱核部的断裂盘地层变形更为明显,属于相对受伤盘;濯河坝向斜西翼的主控断裂——王家湾—大河口逆冲断裂两盘差异明显:向斜核部、断裂下盘构造缝高度发育,整体含气性较差,是页岩气保存条件的欠佳区域,不利于页岩气成藏。通过分析发现,区域应力背景控制褶皱体系,褶皱变形程度决定断裂分布和组合样式,断裂形态决定地层变形和裂缝发育,从而进一步控制页岩气的保存和富集。因此,全面分析构造匹配模式,是研究不同地区页岩气保存能力的先决条件。
