The north-eastern Potwar is present in the foothills of Himalayas on the northern boundary of the Indian Plate and is filled by the Infra-Cambrian to Pliocene sedimentation. The area is affected by the regional structures of the Potwar and the Salt-Range Structures, such as the North Potwar Deformed Zone (NPDZ), the Soan Syncline, the Main Boundary Thrust (MBT) and the Jhelum Fault. Due to complex tectonic-structural framework, it is extremely significant to understand the subsurface structural mechanisms for further hydrocarbons exploration. The 2D seismic data was acquired in the NE-Potwar in the Rawat area is used for this purpose. The current study helps to present rigorous and mechanically feasible structure understanding of the Rawat and associated local structures of the area in the context of the Sub-Himalayas. The study area mainly comprises on the eastern Potwar with tight anticlines and wide synclines with associated thrusts showing collisional regime of the Himalayan Fold and the thrust belt. The structural interpretation and restoration of paleo-section provide a mechanically feasible model for the Rawat area. The interpretation of seismic data shows that this area is associated with conjugate faults and a triangle zone. The results of this study help us to develop understanding in geological history, structural overprint and future leads for hydrocarbons in this geological province.

基于巴基斯坦东北部Potwar盆地地震数据的地下构造调查

东北的Potwar位于印度洋板块北部边界的喜马拉雅山山麓,由寒武纪至上新世沉积所填充。该地区受到Potwar和盐距构造的区域结构的影响,例如North Potwar变形区(NPDZ),Soan向斜线,主边界推力(MBT)和Jhelum断层。由于复杂的构造-构造框架,了解地下构造机制对于进一步的油气勘探具有极其重要的意义。为此,在Rawat地区的NE-Potwar中采集了2D地震数据。当前的研究有助于在次喜马拉雅山脉的背景下,呈现出对拉瓦特和该地区相关局部结构的严格和机械可行的结构理解。研究区域主要包括东波塔瓦地区,其背斜线紧,向斜方向宽,伴有逆冲作用,显示了喜马拉雅褶皱和逆冲带的碰撞状态。古剖面的结构解释和恢复为拉瓦特地区提供了机械上可行的模型。地震数据的解释表明,该区域与共轭断层和一个三角形带有关。这项研究的结果有助于我们加深对这个地质省内碳氢化合物的地质历史,构造叠印和碳氢化合物未来铅的了解。古剖面的结构解释和恢复为拉瓦特地区提供了机械上可行的模型。地震数据的解释表明,该区域与共轭断层和一个三角形带有关。这项研究的结果有助于我们加深对这个地质省内碳氢化合物的地质历史,构造叠印和碳氢化合物未来铅的了解。古剖面的结构解释和恢复为拉瓦特地区提供了机械上可行的模型。地震数据的解释表明,该区域与共轭断层和一个三角形带有关。这项研究的结果有助于我们加深对这个地质省内碳氢化合物的地质历史,构造叠印和碳氢化合物未来铅的了解。
