摘要: 应用沸石矿物的组合形式和分布特征,对克拉玛依油区石炭二叠系的成岩阶段进行分析研究后认为,沸石组合的分带性与地层埋藏成岩作用相一致;分带中的重叠现象与盆地构造运动有关。
在晚成岩期的A、B亚期阶段,方沸石的钠长石化和溶蚀对储层贡献较大。在具备有机—无机反应的成岩体系中,寻找以溶蚀方沸石为主要储集层的油气藏具有一定意义。

Abstract: The diagenetic stages in Carboniferous and Permian farmations of Karanay oilfield are analyzed with zeolite combinaton patterns and distribution characteristic. The zonation of zcolite combination is consistent with burial diagencsis. the overlaping phenomenon is related to basin tectonic movement. In the A and B sub-stagcs of late diagenetic period, the albitization and corrosion of analcime contribute to reservoirs. In the diagenetic system of organic-inorganic change, It is significant to search for reservoirs with corroded anacime.
