摘要
The paper analyzes the characteristic of seismic and the reason for it, and summarizes the key problem and technology of deep volcanic rock seismic data processing which include pre-stack de-noising, signal enhancing and pre-stack migration. Then high-dense automatic velocity analysis, priority offset stack, CRS and PSTM are used in the north of Songliao Basin. From a comparison with former seismic section, the quality of seismic data of deep volcanic rock is increased highly. The result demonstrated that the approaches applied are practical and valid.
