摘要(Abstract)：

通过岩心、薄片观察,结合测井、地球化学数据分析,认为大牛地马五2段主要有利储层发育的成岩作用为溶蚀作用、白云石化作用和破裂作用。综合分析得出马五2段储层成岩相主要包括泥质充填成岩相、去云化成岩相、去膏化成岩相以及白云石化成岩相,对马五2段成岩相的展布进行了深入分析,发现泥质充填成岩相主要沿岩溶沟槽的边缘分布,说明泥质充填相可能受古地貌的控制;去云化和去膏化成岩相主要在较高的部位发育;白云石化成岩相主要受沉积相分布的控制。对马五2段储集空间进行测井识别后认为,成岩相反映了沉积微相所决定的溶蚀差异特征;成岩相的分布反映了古地貌对岩溶储层的控制作用;白云石化成岩相为较为有利的储集相带分布区。
