| Abstract: | The sampling uniformity of observation system indicated the degree of spatial balance of seismic signal in the process of seismic data acquisition,which was essential for the data processing and comprehensive geologic explanation.The uniformity analytical method of 3D observation system was to comparatively analyze the uniformity of each attribute in the system by analyzing and evaluating the uniformity qualitatively and quantitatively,thus to analyze and contrast the uniformity difference from different observation systems to make the choice of 3-D observation more scientific and reasonable.The research result is used in practical production,and good result is obtained for improving the imaging and the quality of seismic data acquisition. |
