This paper deals with the application status of the Crosswell Seismic technology and

describes the Crosswell Seismic acquisition technique and conventional Crosswell Seismic data

processing technology. Some of the major aspects in the application of Crosswell Seismic data are

discussed, and the future trend of Crosswell Seismic technology is forecasted. Current researches show

that the Crosswell Seismic technology could significantly improve the quality of seismic reflection

profiles and the resolution of seicmic exploration and could also detect the exact structure of shallow

strata. It is proved that the Crosswell Seismic technology has a good application prospect in such

aspects of engineering as active fault exploration and geological investigation..
