摘要
准确识别并有效压制多次波是将地震技术应用于油田开发研究的前提。基于动校正后的CMP道集、速度谱、偏移剖面和测井资料分析认为:在主力油层段发育全程多次波与层间多次波;依据测井资料的正演模拟证实,层间多次波严重破坏萨二油层组(S2)的反射波振幅关系。在实际资料处理中采用Q值补偿、地表一致性反褶积和拉冬变换组合方法压制多次波,能够恢复振幅关系,提高地震资料品质。
The accurate recognition and effective rejection of the multiple have become the premise to the studies of oil：field development applied by seismic techniques. By the NMO-corrected CDP gather, velocity spectra, offset profiles and well-logging data, long journey and interbedded multiples are thought to well develop in the major oil reservoirs ; forward modeling of the well logging data reveals that the amplitude relations among the reflected waves of S2 Oil Group are seriously damaged by the interbedded multiples. During the actual data processing, the three techniques are implemented to reject the multiples： Q-value compensation, surface consistent deconvolution and Radon transform. Thus the amplitude relations can be rejuvenated and the quality of the seismic data can be en- hanced.
