Abstract:Based on the refraction time-distance curve equation, we anayze the principle of common-receiver refraction stack imaging technology. The refraction wave of the 2D fault model is stacked in common midpoint domain and common-receiver domain respectively, and the actual 2D seismic data of Hexi corridor is processed comparatively. The results of model and practical application show that the common-receiver domain profile has higher lateral resolution than the common midpoint domain. This method, in combination with other data, can accurately determine the spatial location of fault points on active faults.
