Abstract

The earth surface is the desert hill or desert mountain (200 m high) in many places of west China. Deep layers in the desert mountain have a good potential for petroleum accumulation or petroleum exploration. Because the structure and earth surface are complex, the imaging is difficult in seismic data processing: the static processing is difficult in desert hills, the seismic data have lower S/N ratio and the velocity changing is acute in the lateral direction. We resolve key problems using special ways especially in desert static, prestack removing noise and the PSTM (pre-stack time migration) of complex structures in the mountain. And we attach great attention to the basic processing, for example, fine velocity analysis and better mute. Finally, we get good imaging data by PSTM optimization and velocity modeling.
