Technique Research On High Fidelity Processing Method Of Digital Geophone

With the development of precision requirements in seismic exploration,the development of seismic instrumentation and detector requirements are rising.Only an effectively receiving from the reflected signal from the ground effectively, especially in high-frequency deep weak reflected signal,can we improve exploration accuracy by further indoor processing.There are many advantages in digtal geophone,such as directly digital-outputs, high-fidelity vector field,tilt sensor calibration features.The digtal geophone’s dynamic range is matching with the most advanced seismic instruments,therefore it can record a true characteristics of the seismic waves from the bottom without transformation.This article relies on processing of Alaxin area,which is a new3D3C digital geophone acquisition seismic data in the Songliao Basin, the processing purpose is high fidelity and amplitude-reserved. In order to achieve this,reasonable application of the high-fidelity processing technology is used, at last it will generate a set of digital geophone seismic data preserved amplitude processing parameters and flows for the Songliao Basin. Meanwhile, compare with the analog geophone seismic data on same location,based on the difference between the theoretical, actual data comparing proved that the advantages of digital geophone widely than analog digital.such as bandwidth, the phase characteristics and the dynamic range and so on.
