摘要(Abstract)：

博孜-大北地区巴什基奇克组为深层、超深层致密砂岩储层，岩性致密，亟需揭示储层品质主控因素，建立相配套的有利储层测井评价方法。为单井定量评价其成岩相，充分利用岩心、常规薄片、铸体薄片、扫描电镜等资料，对博孜-大北地区巴什基奇克组致密储层的岩石学、物性、成岩作用类型和强度、成岩矿物等特征进行了研究，并在视压实率、视胶结率、溶蚀孔隙含量和成岩综合系数等参数定量计算的基础上，根据成岩作用强度及其组合特征对储层成岩相分类命名，划分出中等压实弱溶蚀相、碳酸盐胶结相及压实致密相等不同的成岩相类型。通过薄片等资料与测井资料拟合分析，建立了成岩综合系数C_g的测井计算模型，以及定量识别储层成岩相的方法。对X1、Y1等井的测井资料进行了处理，并通过识别结果与物性分析、铸体薄片等的匹配关系，验证了方法模型的可靠性。成岩相测井定量表征方法的建立可为有利储层预测提供指导。
