摘要
3D seismic data of Chengbei fault-ramp reveals that oil and gas mainly migrated along the vertical direction of the faults, and less in the lateral direction and oil-gas migration model along faults is set up. Fault block and nose are the main traps. Then the favorable prospecting targets were predicted, such as the areas between Qidong fault and Zhangdong fault, Zhangbei fault and Zhangdong fault, Hai 4 well fault and Yangerzhuang fault as well as the Guanjiabao-Chenghai area.
