【摘要】 目的研究二叠纪构造层的划分及其构造特点。方法依据三塘湖盆地二叠纪地层与上覆地层的区域性不整合关系在地震剖面上的反映及其不同构造层的构造变形差异性,划分出二叠纪构造层,并对其构造格局和残留构造特点进行研究。结果二叠纪沉积盖层形成后,遭受晚海西期构造运动的影响,导致中央拗陷带残余二叠纪地层中宽缓褶皱和冲断构造组合的发育;在遭受多期构造叠加改造后,残余的二叠纪构造层在盆地中表现为西南部残余厚度大,东北部残余厚度小的现今构造格局。结论二叠纪构造层具有残留盆地的特征,主要含油层分布在条湖凹陷的西南缘和马郎凹陷。更多还原

【Abstract】 Aim To divide Permian tectonic sequence and the feature of residual tectonic.Methods According to seismic section information of the Permian stratum and its overlying formation,the Permian structural layer has been marked off clearly in santanghu basin.Results The Permian structural layer is investigated on its structure pattern and relic characters.The conclusions show that the Permian deposition is in possession of characteristic of wide-folding and reverse faults after undergoing multiphase tectonic activity.Conclusion Oil-bearing formation of Permian is distributing in the southwest of Tiaohu depressiona and Malang depression.更多还原
