The application of high resolution seismic data processing technique in multi-channel shallow offshore engineering seismic surveys

摘要

The high resolution data processing technique of shallow seismic is an important aspect for the engineering geophysical surveys either in land or ocean. In this paper, we present two methods to improve the resolution and Signal-to-Noise rate of offshore engineering seismic data, which are high resolution velocity analysis and KL-transform multiple removal. Coupled with the drilling information, the result showed the excellent accuracy, and solved the engineering geology problems efficiently.
