| 摘 要： | 通过岩性数据、铸体薄片、扫描电镜、压汞曲线及物性等资料的统计分析,对鄂尔多斯盆地八连沟-金庄地区长6储层的岩石学特征、孔隙结构和物性特征进行了研究.结果表明,该区块长6油层组总体物性属于低孔、特低渗储层,孔隙类型主要包括溶蚀粒间孔、残余粒间孔、溶蚀粒内孔、溶蚀填隙物内孔和溶蚀微裂缝5种类型.该区孔隙结构以中排驱压力-中喉道型及高排驱压力-细喉道型为主,具有较强的多变性、复杂性及非均质性.储层物性受沉积作用和成岩作用的综合影响,水下分流河道是形成有利储层的主要相带,胶结作用和压实压溶作用是导致储层物性变差的最主要原因,溶蚀作用产生的溶蚀孔隙是重要的储集空间,裂缝的存在大大改善了储层的物性条件.
