Abstract:Based on the characters of seismtc data ac-quired in Sudan swampy area, and in combinationwith available processing system for BGP seismicdata processing center in Sudan, the paper deter-mined effective and practical processing flowthrough the experimental processing of such keytechniques as match of seismic data of hydrophonewith land geophone, minimum phase processing ofvibroseis data and matching processing of seismicdata acquired by different type of sources:1} mini-mum phase processing of vibroseis data, taking thedata acquired by blasting powder source as stand-and to do match filtering processing, making thedata acquired by vibroseis and blasting powder a-chieve optimal match;②sorting CMP gathers fromdata acquired by two sources, then the surface-con-sistent amplitude processing and surface-consistentdeconvolution processing are carried out. Usingabovementioned-processing flow can finally achievethe migrated sections that are satisfactory to theusers.
