摘　　要：根据铸体薄片、荧光薄片、阴极发光、扫描电镜、物性分析等分析化验资料,对鄂尔多斯盆地白豹地区长4+5段砂岩成岩作用及其对储层物性的影响进行研究。白豹地区长4+5段砂岩储层主要的成岩作用包括压实作用、胶结作用、溶蚀作用。对研究区储层物性起建设性的成岩作用是溶蚀作用;对储层物性起破坏性的成岩作用主要为压实作用和碳酸盐胶结作用;绿泥石胶结作用对储层物性具有双重作用。The effect of diagenesis on physical property of Chang4+5 Sandstone Member in Baibao area, Ordos Basin, was studied on the basis of some analysis data from casting thin section, fluorescence thin section, cathodoluminescence, and SEM. Results showthat(1) the main diagenesis consists of compaction, cementation,and dissolution;(2) constructive diagenesis contains dissolution whereas destructive diagenesis includes mainly compaction and carbonate cementation; and(3) chlorite cementation has not only constructive but also destructive effects on reservoir's physical property.
