More Information
Summary:The invention discloses a post-stack seismic data fracture enhancement method, which comprises the following steps: S1, analyzing the quality of original seismic data, and determining the spectrum characteristics of a well drilling target layer; s2, explaining frequency division, and determining main frequency information corresponding to effective energy; s3, carrying out frequency reduction processing on the original seismic data; s4, carrying out Q compensation; s5, constructing guiding filtering and fracture enhancement processing; and S6, carrying out Yu frequency extraction. According to the post-stack seismic data fracture enhancement method, on the basis of frequency division explanation of original seismic data, after an effective energy range is determined, a set of seismic data volume for fracture explanation is obtained through combination of methods such as frequency reduction, Q compensation, construction of guided filtering, fracture enhancement and Yu frequency extraction; the problem of fract
