Since cross-well seismic can avoid the impact of low-velocity layer and weathering layer for seismic wave, it can acquire high-frequency seismic signals. After processing, high-resolution velocity and reflection imaging can be obtained. During the year 2004-2005, 7 cross-well seismic profiles of Ken 71 block in Shengli oil field have been processed. In accordance with the characters of raw data, we study tomography, tube wave attenuation, CDP MAP, and finite angle stack, complete cross-well seismic data processing. The analysis of the final result shows that cross-well seismic can i-dentify minor faults, small structure and thin reservoirs between two wells.
