Abstract:On the basis of second 3-D seismic acquisition in Baidong structural zone,the paper carried out systematic study on fault system,structural feature and evolution as well as genesis,considering that the faults of Baidong structural zone appears snake-like east-west distribution,local faults are characteristics of arc crisscross and revolve from north to south,forming special cabbage-like structure,and all linked with each other, which is of benefit to trap formation and oil/gas accumulation.The structures in the region are mainly affected by two periods of structural action,which makes the oil/gas do curtain migration toward both wings of structural zone along main faults cutting deep oil source rock and adjustment faults cutting with main faults,forming reservoirs in both north and south wings of the structural zone.There is great exploration potential in the structural zone according to the analysis of reservoir conditions,the main targets in the north wing is Paleogene Ed (Eocene Dongying Formation),and Neocene Pliocene and Minocene in south.
