| 摘 要： | 高分辨率地震勘探技术贯穿于野外采集、室内资料处理和解释各个环节。文章从三维地震资料处理角度出发,探讨高分辨率、高信噪比和高保真度处理的关键技术措施,即波场净化处理,振幅、频率和相位补偿,叠前反褶积,静校正和动校正及叠后频谱整形。最后以实际资料说明经高分辨率处理后,频宽达到350Hz,给解释人员提供优质剖面,为分辨小间距薄煤层奠定基础。

| Abstract: | High resolution seismic exploration technology has been applied to field acquisition,data processing and interpretation at home From the point of 3D seismic data processing,this paper discusses key technical measures of high resolution,high signal-to-noise ratio and high-fidelity processings,i e purifying processing of the wave field,compensations of the amplitude,frequency and phase,prestack deconvolution,DMO,NMO,and reshaping of poststack frequency spectrum Finally given real data which shows that high-quality section with frequency width of 350Hz can be provided for the interpretation personnels after high-resolution processing,which lays the basis for determination of thin coal seam with small spacing |
