| 摘 要： | 应用有机质热演化指标,结合黏土矿物分布规律对伊通盆地岔路河断陷不同构造带储层的成岩阶段进行了划分。在黏土矿物分布、地层水分布规律及成岩阶段分析的基础上,结合薄片和扫描电镜及压汞孔隙分析手段,对岔路河断陷储层成岩作用的类型、分布规律与构造、沉积微相、黏土矿物和地层水的关系进行了研究。结果表明:从南往北相应的成岩阶段深度变浅,梁家构造带、万昌构造带和波太凹陷存在3个次生孔隙带,孤店斜坡带均存在2个次生孔隙带,新安堡凹陷不明显;次生孔隙的形成受有机酸、不整合界面处的地表水淋滤及深部碱性作用控制;不同构造带不同微相内压实和胶结作用对储层的影响程度明显不同。

| Abstract: | This paper first divides the stages of diagenesis by thermal evolution of organic and the distribution of clay for different structural zones in Chaluhe depression.Then,it analyzes the factors affecting diagenesis based on the analysis of structure,sedimentary facies,clay distribution,chemical property of underground water,and the micro character by thin section and SEM.The results show that the depth of the same diagenesis stage in the different sub-structures becomes shallow from southwest to northeast an... |
