In the Qaidam Basin,the overthrust is developed and,because of the influence of fracture,the footwall imaging is difficult and complex.Based on the seismic numerical simulation technology,the authors integrated seismic and logging data to set up a geological model so as to guide the seismic processing and interpretation.The forward results of the Yingxiongling area show that,due to the high speed formation on the hanging wall,there appear monoclinic,local pseudo faults,bedrock pull-up and fault shape change in the footwall.The results obtained in this paper can be used for reference to the seismic data processing and interpretation in Yingxiongling area and exploration target areas of other structural reservoirs in the Qaidam Basin.
