摘 要
The present disclosure discloses a method of obtaining aseismic while drilling signal. The method comprises the fol-lowing steps: arranging geophones by using a first observa-tion method to obtain a first seismic reference signal and asecond seismic reference signal; arranging geophones byusing a second observation method to obtain first seismicdata; arranging geophones by using a third observationmethod to obtain second seismic data; comparing the firstseismic reference signal with the second seismic referencesignal to obtain a first output reference signal, and optimizing the first output signal to obtain a second output referencesignal. The present disclosure obtains square matrix andnear-wellhead seismic while drilling data through the com-bination of geophone square matrix combined observationnear-wellhead observation, and survey line observation,thedata acquisition effciency is relatively high, the signal-to-noise ratio is high,and thus,the problem of near-surfacenoise interference is effectively solved
