摘　　要：江汉油田潭口地区发现碳酸盐岩新类型油藏,为揭示其储层储集特征及油气富集规律,利用岩心、薄片、扫描电镜等资料开展岩性、储层、成藏研究。结果表明:潭口地区四类碳酸盐岩均具有储集空间,颗粒结构的储层储集性能最优;高能相带和建设性成岩作用二元耦合控制了优质碳酸盐岩储层的发育;“优质烃源岩、储层物性、源储压差”三因素共同控制了潭口碳酸盐岩油藏的富集,研究结果为非常规油气开发提供了有利指导。A new type of carbonate reservoir has been discovered in the Tankou area of Jianghan Oilfield.To explore its reservoir characteristics and hydrocarbon accumulation mechanisms,this study analyzes lithology,reservoirs,and hydrocarbon migration using core samples,thin sections,and scanning electron microscopy.The results show that all four types of carbonate rocks in the area possess storage space,with granular structures offering the best reservoir properties.High-energy facies and constructive diagenesis synergistically control the development of high-quality reservoirs,while hydrocarbon accumulation is governed by the interplay of high-quality source rocks,reservoir properties,and source-reservoir pressure differentials.The findings provide valuable guidance for unconventional hydrocarbon exploitation.
