摘要(Abstract)：

根据岩心、岩石薄片、铸体薄片和阴极发光等资料,研究乍得Bongor盆地基岩潜山的岩石类型、储集空间类型、裂缝发育特征、储集空间组合类型及其影响因素。结果表明:研究区基岩潜山储层岩石类型由正变质岩和岩浆侵入岩组成,以混合花岗岩类、花岗岩类和正长岩类为主。储集空间主要包括孔隙和裂缝,局部发育溶蚀洞,其中孔隙以溶蚀孔、破碎粒间孔为主;裂缝包括构造缝、溶蚀缝、解理缝和风化淋滤缝等,以构造缝为主。构造缝以剪切缝为主,占64.0%,产状以高角度缝为主,占60.1%;裂缝的长度主要为0.03～0.15m,开度主要分布在0.01～0.20mm之间;裂缝密度为3.38～15.60条/m,平均为10.02条/m;全充填裂缝占54.3%,其中充填物以硅质、泥质和炭质为主。储集空间组合类型可以划分为孔隙型、裂缝型和孔隙—裂缝复合型。研究区基岩储集空间影响因素主要有构造作用、风化作用、溶蚀作用、矿物充填和岩石性质等。该研究结果对认识乍得Bongor盆地基岩潜山储层特征和指导后期的开发具有参考意义。
