摘　　要：华北东部盆地是典型的多旋回叠加改造型盆地 ,中上元古界、下古生界、上古生界、中生界和新生界普遍具有生烃潜力和储盖组合条件。漫长的地质演化和新生代构造断裂活动形成了上第三系至太古界多层系多类型的油气藏 ,在凹陷、凸起的各部位 ,分布着大型油气聚集带。根据盆地历史演化、勘探程度差异性及油气发现的特点 ,对华北东部盆地油气勘探潜力进行了分析。在该地区应着重研究多勘探层系、勘探程度的差异性和地质理论的新进展 ,充分挖掘各探区内各单元的油气资源潜力 ,第三系深层、前第三系、滩海和浅海应是华北东部盆地 2The basins in the eastern part of North China are the typical multi_cycle composite basins,where the hydrocarbon_generation and reservoir_seal combination conditions exist commonly in the middle_upper Proterozoic,Paleozoic,Mesozoic and Cenozoic.Long geological evaluation and Cenozoic structural and fault activities led to the formation of multiple types of oil and gas pools from Neogene to Archeozoic Era and resulted in a great deal of oil and gas accumulations in uplifts and sags.The exploration potential analysis should focus on the multiple sequences,exploration extent and the advanced geological theories for discovering more oil and gas resources.The deep formations in the Tertiary,pre_Tertiary,littoral areas and offshore will be the most favorable exploration fields in the basins of the eastern area in North China for 21st century.
