| 摘 要： | 通过岩芯观察、镜下薄片、扫描电镜和X衍射分析等资料,对松辽盆地龙西地区泉四段砂岩的岩石学特征、成岩作用类型、成岩阶段划分和成岩共生序列及孔隙演化特征进行了研究。结果表明:龙西地区泉四段主要为长石质岩屑砂岩,局部为岩屑质长石砂岩;经历的主要成岩作用类型有压实作用、自生石英胶结作用、自生黏土矿物胶结作用、碳酸盐胶结作用、交代和溶蚀作用等;龙西地区泉四段砂岩为中成岩阶段A期,且细分为A1和A2亚期;随着成岩演化,压实和胶结作用使得原生孔隙减小,而溶蚀作用使得储层孔隙结构得到改善;孔隙类型由缩小粒间孔组成变为由缩小粒间孔和溶蚀粒间孔组合组成。 |

| Abstract: | Based on core,cast thin section,scanning electron microscope,X-ray diffraction and so on,the characteristics of petrology,types of diagenesis,division of diagenetic stage,diagenetic concordant sequence and porosity evolution in Quan-4 Formation sandstone in Longxi area of Songliao Basin are studied.The results show that the lithology is mainly feldspathic litharenite,and secondly lithic arkose;types of diagenesis are compaction,authigenic quartz cementation,authigenic clay mineral cementation,carbonate ceme... |
