摘　　要：为探究蓬莱油田l62低阻油层微观成因机理及其宏观地质成因模式,运用微观与宏观相结合的研究方法,利用实验数据,分别对油田各主力小层的粒度、泥质含量、蒙脱石含量、束缚水饱和度、阳离子交换能力、古气候、古物源进行了研究,并进一步做耦合对比分析。研究结果表明:l62低阻油层为高束缚水-黏土附加导电复合成因低阻油层,是受母岩岩性、搬运距离以及古气候共同控制形成的。该研究对渤东地区低阻油层的勘探部署具有很强的指导意义。Microscopic and macroscopic means were combined to explore the micro-genesis mechanism and macrogenesis patterns. Laboratory test data was used to respectively study the reservoir particle size,shale content,montmorillonite content,bound water saturation,cation exchange capacity,paleoclimate and paleo-provenance of each major layer. In addition,the coupling comparison analysis was also provided. Research indicates that the l62 lowresistance reservoir is considered as a composite genesis of high bound water saturation and additional conduction of clay,which is jointly controlled by the parent rock lithology,handling distance and paleoclimate. This research could provide certain guidance for the exploration and deployment of low-resistivity reservoirs in the eastern Bohai.
