Abstract：In view of surface seismic conditions and requirement of geologic task in Mahu slope area of Jungar basin, the paper presented model-building method of static corrections in seismic data pieces-jointed processing. Taking field statics in whole work area as controlling grid, the method mainly uses the refraction statics for integrative static corrections model-building, so that solved the issue to put three blocks of 3-D seismic data together side by side (without mis-tie and phase difference) and clarified low-amplitude structures, stratigraphic unconformity relationship and fault location in the area, at the same time, ensuring the structural reality in juncture region of three blocks of 3-D seismic data. Meanwhile, the Triassic Baikouquan Formation 3-rd sand Member litho-stratigraphic traps of northern Ma 005 well in juncture region of three blocks of 3-D seismic work areas were discovered, displaying good oil/gas exploration prospect in the region.
