The invention discloses a denoising method based on
well logging-seismic combination. The method is characterized in that relationship is established between synthesis records manufactured by
well logging information and seismic information,
noise in the seismic information is removed, and the
signal to
noise ratio of the seismic information is increased. Because the seismic information, especially a high-frequency component, is submerged into the
noise and the finding of a noise rule is difficult, the conventional denoising method only utilizes the seismic information per se, so that the removal of the noise is difficult. The denoising method has the advantages that the synthesis records obtained by converting the
acoustic wave well logging information are regarded as noise-free expected output, and a seismic
record is used as input; when mathematic relationship between the synthesis records and the seismic
record is established, an effective
signal is enhanced, a noise
signal is weakened, and the purposes of denoising and increasing a
signal to noise ratio are realized; by combining the synthesis records of the well
logging information and the seismic
record, the nonregular noise can be removed.
