摘要: 根据对任丘、东辛、孤岛、北 大港及曙光-欢喜岭大油田形成的分析,发现它们的主要烃源岩是沙三段,而排烃并发生二次运移时间在早第三纪末的前后,油田的形成、定型则在晚第三纪末至第四纪。沿渤海的4个大油田,由于断沟通,下第三系中油气发生再次运移,进入上第三系中。原油也因降解而变重、变稠。

Abstract: Based on the analyses for formation of Renqiu, Dongxin, Gudao, Beidagang and Shuguang-Huanxiling oilfields, it is found that their principal hydrocarbon source rock is Shasanduan unit,the hydrocarbon expelling and secondary migration occurred at about the end of Paleogene,and the forming and finalizing of such oilfields are accomplished in the end of Neogene to Quarternary. The four large oifields along Bohai bay, due to faults connection and communication, the hydrocarbon of Paleogene again migrated into Neogene. The crude oil was also affected by degradation and became more viscous and heavier.

Key words: Bohai bay basin, large scale oilfield, primary reservoir, oil and gas migration, secondary reservoir, reservoir formation, mode
