| 摘 要： | 通过对靖边地区的马五14层岩样进行扫描电镜、铸体薄片以及压汞分析, 对该层碳酸盐岩储集层的孔隙进行了分类与特征研究, 认为次生孔隙中的溶蚀孔(缝)和晶间孔为该储集层的主要储集空间; 其储集空间物性特征、平面变化规律和古岩溶发育特征表明, 古岩溶作用对碳酸盐岩储集层起着明显的改善作用; 其次生孔隙的形成过程可划分为地表淡水控制岩溶期与埋藏溶蚀期2 个不同阶段。

| Abstract: | In this paper, the samples are collected from Majiagou-514 sub-member in Jingbian area and analyzed by scanning electronic microscopy (SEM), casting thin section and mercury penetration. The category and feature of pores in carbonate reservoir dominated by dissolved and intercrystal pores are presented. The reservoir property has been obviously improved by the paleokarst process. Its genetic process of secondary pores can be divided into the meteoric water controlled karst phase and the buried condition controlled solution phase. |
