Abstract：The paper carried out analysis and comparison of shooting factors of two different sources and seismic records produced in different surface conditions, and pointed out that the vibroseis is selected in foreland and gravel zones and dynamite source is selected as shooting source in desert area or farmland; on the basis of well-selected shooting lithology, we should make our effort to shoot in 3-5m under the top of high-velocity layer, which can get better records by dynamite source, and correct selection of parameters of vibroseis such as the number of vibrator, driving amplitude, sweeping length and frequency is also the guarantee that can acquire good records of vibroseis. Joint application of dynamite source and vibroseis is effective way to acquire high-quality seismic data in complex surface conditions.
