摘要: 致密储层成因及有利储层分布预测是制约当前徐家围子断陷沙河子组致密气勘探的关键因素。本次研究综合运用沙河子组普通薄片、铸体薄片、扫描电镜、阴极发光、电子探针、X衍射及物性测试等多种资料,系统分析徐家围子断陷沙河子组致密砂砾岩成岩作用特征。结果表明:研究区沙河子组可划分为强压实泥质杂基充填成岩相、中压实长石岩屑溶蚀成岩相、中压实石英次生加大成岩相、中压实绿泥石环边胶结成岩相和弱压实碳酸盐胶结成岩相等5种成岩相;由沉积作用形成的碎屑矿物组分、结构差异是各成岩相成岩演化的物质基础,决定了其初始孔隙度的差异;强压实和黏土杂基充填是造成砂砾岩储层物性损失的主要原因,长石岩屑溶蚀和绿泥石环边胶结有利于物性保持和改善。不同成岩相中成岩作用类型和强度各不相同导致不同成岩相间宏观物性和微观孔隙结构差异,其中中压实长石岩屑溶蚀成岩相和中压实绿泥石环边胶结成岩相是沙河子组储层最有利的成岩相带。
