综合运用物性资料、岩石薄片、铸体薄片、扫描电镜以及阴极发光等测试方法,对环江-刘峁塬地区长4+5砂岩储层岩石学特征、储层特征、成岩作用及有利成岩相带进行了研究,划分出四种成岩相,其中绿泥石薄膜胶结+粒间孔、长石溶孔相和高岭石胶结+粒间孔、长石溶孔相是储层发育有利的成岩相带,水云母胶结相次之,铁方解石胶结相最差.油气地质意义表明,长4+5砂岩储层生、储、盖配置合理,成藏条件优越,油气资源潜力巨大,可作为下步重点勘探目标.

Based on physical data, rock slice, cast slice, scanning electron microscope and cathode luminescence technique, we studied the petrological characteristics, reservoir physical property diagenesis and favorable diagenetic facies of Chang 4+5 reservoir in Huanjiang-Liumaoyuan area. The result showed that four kinds of diagenetic facies were classified on the base of diagenesis characteristics. Chlorite cementation plus intergranular pore, feldspar corrosion facies and Kaolinite cementation plus intergranular pore, feldspar corrosion facies constructed the favorable diagenetic facies of reservoir development. It revealed that Chang 4+5 sandstone reservoir contains huge potential for oil and gas resources and can be the next primary target for exploration because of its superior accumulation conditions.
