| 摘 要： | 古近系双阳组是在吉林省伊通盆地莫里青断陷中，油气赋存的主要层位,储层主要为湖底扇和扇三角洲的砂体。依据双阳组储层的大量薄片、扫描电镜、粘土矿物分析的资料研究了该储集层的成岩作用。研究结果表明双阳组储集层：成岩作用经历了压实、压溶、胶结、交代和溶解6方面的作用。双储集层中的自生粘土矿物蒙皂石向伊利石转化具有明显的特征：主要演化过程经历了蒙皂石渐变带，第一迅速转化带和第二迅速转化带，相应的成岩作用阶段可划分为早成岩阶段B期、晚成岩阶段A1期和晚成岩阶段A2期。依据在垂向上的成岩变化,建立了莫里青断陷双阳组储集层的成岩作用演化序列。在垂向上成岩作用的类型和强度均存在明显的差异，造成了储层物性的垂向分带。

| Abstract: | The Shuangyang Formation of Paleogene is the important oil-gas reservoir interval in the Moliqing Faulted Depression of the Yitong Basin. Based on a great deal of thin sections, scanning electron microscope observations and data of clay minerals X-diffraction analyses and other methods, the diagenesis of the Shuangyang Formation reservoirs is revealed. The results show that the reservoir diagenesis includes compaction, pressure-solution, cementation, replacement and dissolution .The conversion of montmorillonite into illite is a typical feature in the Shuangyang Formation reservoirs. It took place a gradual transforming zone, the first rapid transforming zone and the second rapid transforming zone. Correspondingly the diagenetic stage is divided into the early diagenetic B stage, late di-agenetic A1 and diagenetic A2 stages. The evolution succession of diagenesis of the Shuangyang Formation reservoirs is established according to the vertical diagenetic evolution. The types and intensities are all different in the vertical direction, which cause the vertical zoning of reservoir properties. |
