Abstract: In this paper, on the base of analyzing the features of gravity anomaly, and combining with the research results of the former in the regional geology, then the structural features of Bohai sea were determined, and the tectonic units were divided. After the contact was studied between the feature of local gravity anomalies and the distribution of oil/gas fields, the oil/gas distribution rules were discussed. The results showed that Tanlu fault controlled the regional tectonic evolution and the boundary of the tectonic units in Bohai sea of Bohai bay basin; there were a lot of local structures and faults, then formed many favorable traps and systems of migration and reservoir for oil and gas in Bohai sea of Bohai bay basin; there is the stronger relativity between the distribution of oil/gas fields and the local gravity highs; the relief areas (i.e. local gravity highs) surrounded by these petroleum generation depressions are the most favorable potential targets for the oil and gas exploration; the fault zones (i.e. the areas between the local gravity highs and the local gravity lows) between the depressions and the relieves are also the significant areas in the study area.
