Abstract

Over the years, Vibroseis method has become the principal data acquisition method in land seismic exploration. For half a century this technology has achieved great success in land seismic exploration. However, this method seems to reach its limits as the search for energy resources continues. Many practical issues arising from field operations have remained theoretically unexplained, for example, inaccurate wavelet estimation. This paper focuses on a new vibrator-ground model to simulate the filtering effects produced by the coupling system of the baseplate and the ground as well as the coupling system between the captured ground mass near the vibrator baseplate and the surrounding earth. This new model is referred as the Vibrator-Coupled Ground Model in this paper. Experimental results show that the weighted-sum ground force, when filtered by the Vibrator-Coupled Ground Model, is proportional to the far-field particle velocity whereas the unfiltered signals are not.
