Abstract
Comparison of single point acquisition seismic data on land with the seismic data collected by combined geophone, the original single shot has the characteristics of heavy noise and low resolution. It is necessary to effectively remove noise and improve resolution in order to meet the geological needs of thin sand body recognition. Using frequency division linear noise attenuation technology can effectively eliminate the influence of surface wave interference, fine denoising in multiple links, and improve the signal-to-noise ratio of data; near-surface Q-compensation and two-step surface consistent deconvolution are used to recover the effective signal energy. After stacking, the seismic frequency band is further broadened by spectral shaping based on global statistical wavelet. The bandwidth of seismic processing results reaches 6–90 Hz, the synthetic record of new drilling with this seismic data matches well. The combined application of many technologies has formed a high resolution processing method and technical process for single point acquisition seismic data, which can electively improve the imaging quality of seismic data.
