Abstract
The complexity of seismic exploration targets makes the exploration process more difficult and requires higher resolution of seismic data. Singular Methodology (inverse Q filtering, spectrum shaping, etc.) is limited in improving the resolution of seismic data and cannot meet the requirements of data interpretation. In this regard, combining time-varying frequency division deconvolution and matching pursuit (MP) methods, first perform time varying frequency division deconvolution processing on the original signal, and then use matching pursuit to remove the strong reflection seismic event and reconstruct the signal. Which can reflect the characteristics of reservoirs. By testing analog signals, deconvolution and matching pursuit methods improve the signal resolution. In the actual seismic data analysis, the comprehensive use of several methods can better identify the distribution characteristics of the effective tight carbonate reservoirs, and correspond well with the actual geological structure and drilling data. Which also provides a reference basis for further capacity analysis.
