【摘要】 合肥盆地受大别造山带和郯庐断裂的双重控制和影响,集挤压逆冲、走滑拉分、拉张等成盆动力机制于一身,构造演化极其复杂。针对该区地质背景复杂的特点,通过地震资料层位标定和对比追踪,进行构造解释,分析了该区地质构造特征及演化,讨论了各个地质构造阶段的油气地质意义。更多还原

【Abstract】 Controlled and influenced dually by Dabie Orogene and Tanlu Fracture,Hefei Basin is characterized by such dynamic mechanism of basin formation as extrusion thrust,strike-slip pull-apart and extensional stress,and the structure evolution is quite complicated.In view of the complex geological background of this area,through horizon calibration and contrast tracing of seismic data,structural interpretation was carried out,geological structure and evolution of this area was analyzed,and hydrocarbon geological significance of each tectonic stage was discussed.更多还原
