Research On Phase Auto-adaptive Correction Method For Seismic Signal Reconstruction

In this paper,freq uency split seismic acquisition method with different resonant frequency geophone is studied,seismic signals which received by different resonant frequency geophones should be corrected in phase then they can be reconstructed as a new broadband seismic signal with fidelity.In this paper,adaptability problem is mainly discussed,the adaptability of phase correction is solved by adopting the technical measures such as published literatures,phase adaptive correction formula is derived,tested by field data,the innovative is: Based on fixed parameter phase correction method,a three-parameter phase auto-adaptive correction formula is derived,programmed with C and Fortran.After reconstruction processing,frequency split acquired seismic data is reconstruc ted as broadband seismic signal with fidelity,which proves that the new seismic signal reconstruction technology has strong adaptability.Research in this paper has achieved an ideal results,improved the adaptability of phase correction in seismic signal reconstruction method,a solid foundation for future broadband seismic signal reconstruction with frequency split seismic acquisition method has been settle.
