Seismic Data Dual-Consistency Processing Technology in Coastal Zone

In the seismic exploration in coastal zone, several kinds of sources and receivers are common in use. Differences in shooting, receiving and surface conditions may result in different energy, frequency and phase of the record which seriously influence the stacking effect. Based on the difference analysis of seismic data in a coastal zone, with wavelet matching, using dual-consistency processing technique, combined with shooting consistency correction and receiving consistency correction, the problem of wavelet difference caused by different shooting and receiving conditions has been well solved. Taking the daily seismic data processing of a 3D Project in a foreign country as a case, we performed the dual-consistency processing and it has brought out good imaging results by eliminating the inconsistency of energy, frequency and phase.
