Analysis on high and large dune field shot and positioning point integrated deflection effect in Talimu basin

Most of Talimu basin is covered by desert, and its surface structure has quick change in long direction and lateral direction. The thickness of low decreasing ground is from 10m to100m, and even reaches to 150m. Bad excitation and receiving condition affect the quality of seismic data. It could effectively improve excitation and receiving condition and provides better seismic data through the measures as the shot and positioning point integrated deflection and the new thought of avoiding high and finding low, the method of moving the shot point and positioning point from high and large dune field to low land.
