摘要
Abstract
Yingcheng formation which buried mostly deeper than 4 000 m is abundant in volcanic rock in the north of Songliao Basin. Because the volcanic rock reservoir is deep and formation velocity varies greatly, the seismic section is low S/N and the imaging of the object is generally bad. The article analyses 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 is practical and valid.关键词
