白音查干凹陷腾格尔组储层特征及影响因素

通过薄片、物性分析等资料和数据,对白音查干凹陷腾格尔组的储层岩石学特征、孔隙结构、孔渗性特征等展开对比分析,认为储层物性受沉积环境及后期成岩作用所控制,腾格尔组不同沉积微相物性差异较大,成岩改造作用主要影响岩石的孔隙类型、孔隙数量、孔隙结构及分布,是控制腾格尔组储层物性的重要因素。

The Reservoir Characteristics and Influencing Factor of Tengger Group in Baiyinchagan Sag

The reservoir properties, prosity structure and properties of porosity ＆ permibility of Teng- get Formation in Baiyinchagan sag are studied by numerous data such as thin section and physical analysis. It is proved that the reservoir properties are controlled by sedimentary environment and diagenesis. The reservoir properties of Tengger Group varies apparently because of different microfacies. Diagenesis is the main fluence factor of reservoir pore type, pore scale, pore structure, pore distribution and permeability.
