Abstract: Receiver positioning correction is one of the main technical problems in sea seismic exploration. This paper illustrates the principle of receiver correction method using refracted wave traveltime, deriving the correspond formulas and the technical workflow. This paper improves the inversion accuracy by means of iteration inversion of the sea-water velocity and bottom velocity. The real data processing results show that it surpasses the acoustic positioning system.

Key words: sea seismic exploration, refraction wave, drifting correction, secondary positioning
