东濮凹陷兰聊断裂带的形成演化可分为两个时期 5个阶段 ,即中生代、新生代时期和挤压、初裂、强裂、萎缩、余动阶段。兰聊断裂带油气圈闭类型多 ,根据油气地质特征、圈闭所处位置、遮挡条件和产状等 ,可分为鼻状构造和半背斜构造、上翘物性遮挡岩性圈闭、潜山圈闭、礁体圈闭、地层不整合圈闭、地层超覆圈闭、古河道岩性圈闭及推覆构造圈闭 8种类型 ,而油源丰富、油气运移条件好、通道多及水下扇砂体和构造控制则是油气聚集的主要因素。
The formation and evolution of the Lanliao fault zone in Dongpu Depression can be divided into five stages, ie, the Mesozoic and Cenozoic periods and the compression, primary cracking, strong cracking, atrophy and remnants during the two periods. There are many oil-gas trap types in the Lan-Lia fault zone. According to the geological features of oil and gas, the location of traps, the occlusion conditions and the occurrence, etc., they can be divided into nasal structures and semi-anticlinal structures, with uplifting properties blocking lithologic traps, Mountain traps, reef trap, stratigraphic unconformity trap, stratigraphic overrun trap, ancient channel lithologic traps and nappe tectonic traps 8 types, rich in oil resources, good hydrocarbon migration conditions, and more channels And subaqueous fan sand bodies and structural control are the main factors of oil and gas accumulation.
