摘要(Abstract)：

基于岩心、薄片观察、测井、录井及分析化验资料,研究义东地区下古生界碳酸盐储层的裂缝发育特征、期次及成因机制。结果表明:义东地区发育两大类五小类裂缝,构造裂缝包括全充填或半充填直立裂缝和半充填或无充填斜交裂缝,成岩缝包括全充填水平裂缝、构造扩溶裂缝和缝合线扩溶裂缝。研究区发育3期裂缝,依次为水平裂缝、斜交裂缝和近直立裂缝,裂缝发育期次与构造演化阶段具有较好的匹配关系。裂缝发育主要受断裂、地层结构和岩性的控制,断裂发育区灰岩、白云岩与泥灰岩的互层具有勘探潜力。该成果对类似地区碳酸盐储层裂缝的研究具有借鉴意义。

关键词(KeyWords)：碳酸盐岩储层;成因机制;裂缝特征;裂缝期次;义东地区
