【摘要】 通过对大庆长垣中部杏树岗、高台子和太平屯构造扶余油层的地震资料解释和断裂分析,编制了研究区扶余油层不同时期的构造图。从扶余油层构造变形特征的研究发现,青山口组沉积前,扶余油层底面表现为两隆夹一凹的构造格局,而明水组沉积末期反转变形后则转变为两凹夹一隆的构造格局,这说明明水组反转变形前的构造格局也决定了嫩江组末期所形成的扶余油气藏的分布。更多还原

【Abstract】 By the analysis of seismic data interpretation of Fuyu reservoir in Daqing Placanticline, the palaeotectonic maps of different times have been compiled. From the study of deformational characteristics of Fuyu reservoir, the structural framework has been found to be "a sag between two uplifts’’ before the deposition of Qingshankou layer, and it has been changed into the structural framework of "a uplift between two sag" after reversion deformation of Mingshui formation. This indicates the structural framework before reversion deformation of Mingshui formation also determines the distribution of Fuyu reservoir formed in Nenjiang period.更多还原
