通过典型地震剖面解释及钻井资料分析 ,认为济阳坳陷早第三纪末沿北西西向断层多处发生过正反转活动 ;渐新世末由郯庐断裂左行走滑活动形成的右旋压扭应力场控制了反转构造的形成 ;断层后期正反转特征与其前期拉张特征间存在有机的联系。文章还对正反转构造与油气成藏的关系进行了初步探讨
Based on the analysis of typical seismic profiles and drilling data, it is concluded that there are many positive and negative inversion events along the NW-NW faults at the end of the Early Triassic in the Jiyang Depression. At the end of Oligocene, the right- The torsional stress field controls the formation of inversion structures. There is an organic connection between the positive and negative inversion features at the later stages of the fault and its early tensile characteristics. The article also discussed the relationship between the inversion structure and hydrocarbon accumulation
