The invention relates to a multi-component converted wave static correction method by using surface waves, which comprises a step of solving stratigraphic classification and transverse wave velocity of a superficial layer through the extraction of the surface waves and the inversion of frequency dispersion curves based on Rayleigh surface waves in a shot record, so as to accurately calculate static correction quantity of detection points of converted waves. The test processing on two-dimensional three-component of a certain block in Daqing shows that a transverse velocity non-uniform body of the superficial layer generates a larger static correction time difference; and the processing on three-dimensional three-component data of a certain coal mine in Huainan shows that the static correction time difference of over 20 milliseconds can also occur due to the low and transversely non-uniform transverse wave velocity even in a flat plain terrain, and for a coalfield high-resolution seismic exploration to recognize minor faults of about 3 meters, the static correction time difference is a non-ignorable error. Application tests in three-component seismic data processing in two regions achieve a better processing effect and prove that the multi-component converted wave static correction method by using the surface waves is a feasible method.
