| 摘 要： | 本文参阅国内外有关次生孔隙的研究报告,结合本油田实际,阐述了文东地区沙三中7～9砂层组砂岩中次生孔隙的形成主要依赖于颗粒的溶解。砂岩中酸性介质的成因有两种,即有机成因和无机成因。论文还论述了颗粒溶解对砂岩成分的影响,并对其成分恢复进行了尝试性研究。

| Abstract: | This paper points out that the formation of sandstone secondary porosity of the 7-9 sandstone layers of the middle member of Sha-3 formation in Wendong oil field mainly depends upon dissolution of grains, The divided acidic medium in sandstone can be divided into(1) organic origin-and (2) inorganic origin. The paper describes the influence of grain dissolution on sandstone composition and studies how to restore the sandstone components. |
