摘要
东营凹陷通王地区中古生界油源主要来自于牛庄洼陷新生界Es4、Es3和Ek2烃源岩,新生界生成的油气在异常压力作用下通过断层、不整合和砂体输导体系向中古生界碳酸盐岩、碎屑岩储层运移。结合油源特征、生储盖组合及输导体系特征,将研究区油气成藏模式归纳为新生古储-复合运移模式,油气藏类型主要有不整合、断层和岩性油气藏。
The hydrocarbon in Mesozoic and Palaeozoic stratum in Tongwang area of Dongying depression mainly came from the Es_4、Es_3 and Ek2 source rock of Cenozoic stratum in Niuzhuang sag.The hydrocarbon generated from Cenozoic source rock migrated to Mesozoic and Palaeozoic carbonates and fragmental reservoir rock driven by the abnormal pressure through fault,unconformable surface and sandstone conveyer system.According to the oil-source features,source rock-reservoir-cap rock assemblages and conveyance system characteristics,the model of pool-forming in Mesozoic and Palaeozoic in Tongwang area of Dongying depression is summed up as the newer source,older reservoir,and complex migration.The fault reservoir,unconformable surface reservoir and the lithologic reservoir are the main types of reservoir in Tongwang area.
