Through the seismic data interpretation and fault analysis of Fuyang oil reservoirs in the structures of Xingshugang, Gaotaizi and Taipingtun in the middle of Daqing Placanticline, the faults in the oil reservoirs are characterized by the graben belts on the seismic profile. The faults are numerous, small-scale and spread in the form of the belts horizontally. The fault activities of Fuyang oil reservoirs mainly pass through four periods: Qing No. 1 Member deposition period, the sedimentary end of Qingshankou Formation, the sedimentary end of Yaojia Formation and the sedimentary end of Mingshui Formation. The multi-stage movement faults and the structural inversion happened in the end of Mingshui Formation present obviously controlling actions to the hydrocarbon migration and reservoir-formation of Fuyang oil reservoirs.%通过对大庆长垣中部杏树岗、高台子和太平屯构造扶杨油层的地震资料解释和断裂分析,发现扶杨油层断层在地震剖面上表现为地堑带,平面上呈带状展布,具有数量多、规模小的特征.研究区扶杨油层主要经历4期断裂活动:青一段沉积时期、青山口组沉积末期、姚家组沉积末期和明水组沉积末期.多期活动的断层和明水组末期构造反转对扶杨油层油气运移和成藏起明显的控制作用.
