Abstract

[

This paper discusses the methods and applications of seismic interferometry in seismic-while-drilling (SWD) experiments. The results show that the deconvolution method can suppress the source effects and enhance the resolution of the results.

,

Seismic interferometry was used to process the data collected with seismic-while-drilling (SWD) experiments at the Daqing Oilfield. The experiments simultaneously recorded the data at the drilling stem and on the ground. After conducting the frequency and the energy property analysis, the data was processed using the correlation and deconvolution method. Seismic data was then obtained from excitation of the drill bit. The result maps show that the deconvolution method can suppress the source effects and enhance the resolution of the profile, and that the vertical stacks enhance the seismic response of the subsurface. The interferometry process after band-filtering can obtain maps with very high resolution. Seismic interferometry by deconvolution shows great advantages based on the results of this experimental data. The method can also be applied to the SWD data and the ambient seismic data to obtain better processing results.
