义东地区碳酸盐岩储层裂缝特征、期次及成因机制
|
摘要
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。
The features and stages,formation mechanism of fracture of carbonate reservoir in Yidong were investigated based on observation of core samples and thin sections,well logging data as well as analysis of laboratory data.There are two major fractures in the Yidong area.The tectonic fracture includes full or semi-filled vertical fracture and semi-filled or non-filled oblique fracture.The diagenetic fracture includes fully filled horizontal fracture and tectonic expansion fracture,suture expansion fracture.There are three developed fractures in the studied area,followed by horizontal fracture,oblique fracture and near vertical fracture.The period of fracture had a good matching relationship with the tectonic evolution stage.The development of fractures are mainly controlled by faults,strata structure and lithology.The interlayer of limestone,dolomite and marlstone in fracture zone is great scope for potential for exploration.
