摘要
观测系统采样均匀性是指在地震资料采集过程中地震信号采样的均衡程度,它对地震资料处理和地质解释至关重要。提出的三维观测系统均匀性分析方法是指通过定性、定量分析三维观测系统面元的各种属性的均匀情况,从整体上对比分析不同观测系统的采样均匀性差异,使三维观测系统的选择更加科学、合理。将研究成果应用到实际的生产当中,达到了提高采集资料品质,改善成像效果的目的。
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.
