Matching method and device for seismic data collected by well shot and vibroseis in mixed mode

The embodiment of the invention provides a matching method and device for seismic data collected by a well shot and a vibroseis in a mixed mode, and the method comprises the steps: adjusting a vibroseis record and a well shot record in the seismic data to the same energy level; extracting a well shot record and a vibroseis record from the seismic data, and performing minimum phasing on the vibroseis record to obtain the vibroseis record after phase conversion; de-noising the vibroseis record and the well shot record after phase conversion; carrying out longitudinal energy compensation on the denoised vibroseis record and the denoised well shot record; adjusting the phase recorded by the vibroseis after longitudinal energy compensation into a mixed phase; superposing the vibroseis record of the mixed phase and the well shot record after longitudinal energy compensation to obtain superposed data; and eliminating the time difference between the vibroseis record and the well shot record in the superposed data.
