Abstract：The seismic data closure is a necessary work in 2D seismic data processing. The former seismic data processor needs to carry out hand closure by making paper section. This traditional method not only introduced man-made mis-tie, but also is time-consuming and with an efforts. The paper presented a method that uses module relevant to Promax processing software to carry out 2D seismic data closure, and concretely including: accurately acquiring cross-point file, closure at single point, inverse cross-point closure (handing wall and heading wall of fault, tilted stratum), multi-point closure and circle closure.
