Abstract: This text is based on the exploration achievement of near 40 years and the data analysis of more than one hundred drilled traps on in Bohai. The characteristics of oil fields and oil-bearing structures have been studied. The relationships between the characteristic of hydrocarbon reservoir and the action of fault system have been discussed in Bohai. It is found that the draping anticline on salient and the wrench-compression anticline on low salient are the most valid type of hydrocarbon-bearing pool. Both Neogene Guantao and Minghuazhen Formations are major oil-bearing series and Paleogene Dongying Formation and Shahejie 1&2 member are secondary ones. The distinctive history of basin developing and especially Neogene Tan-Lu fault system activated strongly again affected the formation of hydrocarbon reservoir significantly in Bohai.
