以钻井、地震资料为基础,在辽东湾地区建立古近系东营组东二段、东三段岩性、电性特征及其对比关系;建立古生物组合鉴别特征,总结不同古地理演化对生物地层的影响;明确段地震反射特征及其在三维空间内的变化规律。通过建立这段地层的正确对比关系,解决了东营组内部地层矛盾问题,同时探讨了地层与油气分布的关系,为辽东湾地区的地层研究及相关的勘探工作提供了有益指导。
Based on drilling and seismic data, the lithologic and electrical characteristics of the Dong 2 Member and the East 3 Member of the Paleogene Dongying Formation were established in the Liaodong Bay area. The characteristics of palaeontology assemblage identification were established. The evolution of different paleogeographic evolutions to the biostratigraphy The characteristics of seismic reflection and its variation in three-dimensional space are clarified. By establishing the correct contrast between these strata, the problem of formation contradiction within Dongying Formation was solved. Meanwhile, the relationship between strata and oil and gas distribution was discussed, which provided useful guidance for stratigraphic research and related exploration in Liaodong Bay.
