Abstract: A method for estimating the depth-domain seismic wavelets from depth-domain seismic data and synthesizing depth-domain seismic records. The method includes: obtaining depth coordinates and P-wave velocity v and density from well log, calculating a corresponding reflectivity series r; performing constant-velocity depth conversion for a seismic trace S and a reflectivity series r by using a velocity vc as a reference velocity to obtain the converted seismic trace S1 and the converted reflectivity series r1; and estimating a depth-domain seismic wavelet w based on the Gibbs sampling method; synthesizing depth-domain seismic record by using the P-wave v, the reflectivity series r and the estimated depth-domain seismic wavelet w.

Abstract: The present invention discloses multifunctional blending equipment, including a clear water supply system, a spray system, a mixing system, a powder material storage and transport system, a mixing tank, a discharge system, and an electrical control system.
