| 摘 要： | 根据砂岩薄片、铸体薄片、扫描电镜和X衍射对储层进行综合分析和研究。认为华池—白豹地区长6砂岩储集层处于中成岩作用的A阶段。本区砂岩储集层在埋藏成岩过程中发生的成岩作用主要为压实与压溶作用、胶结作用、交代作用、溶蚀作用和破裂作用。研究区砂岩可分为五种成岩相：碳酸盐胶结成岩相、泥质胶结成岩相、绿泥石—碳酸盐胶结成岩相、硅质充填及次生加大胶结成岩相和长石溶蚀成岩相五种成岩相。其中长石溶蚀成岩相物性最好，碳酸盐胶结成岩相和硅质充填及次生加大胶结成岩相对物性破坏最强。

| Abstract: | Based on the date analysis of casting lamella,scan electron microscope and X-ray diffractions for discussing and studying reservoirs.HuachiBaibao Area Chang6 formation sandstone reservoirs belong to the "A" late diagenesis,the diagenesis include compaction and pressolution,cementation,metasomasis,dissolution and fracture.The diagenetic facies of the study area can be divided into five types: carbonate cementation diagenetic facies,argillaceous cementation diagenetic facies,chlorite-carbonate cementation dia... |
