Research on Combination Denoising Methods for single-sensor high-density seismic data
In order to promote further exploration and development of oil and gas fields in the old area and solve the exploration and development difficulties of complex and hidden oil and gas reservoirs,this study focuses on the processing methods of single-sensor high-density seismic data.The characteristics of single-sensor high-density seismic data are small bin wide frequency band,wide azimuth,high shot density,and low signal-to-noise ratio.Therefore,it is crucial to solve the signal-to-noise ratio problem in indoor data processing.This study is mainly based on the time-frequency domain characteristics of seismic data,and utilizes graded curved wave transform to combine and suppress pre-stack noise.
