【摘要】 在岩性地层勘探中,地震资料的分辨率常常制约着岩性圈闭的识别能力。而高分辨率地震资料处理涉及多个环节,其中反褶积是高分辨率地震资料处理的关键技术。在地表一致性反褶积的基础上,采用子波整形反褶积将最小相位子波变换为零相位子波,在一定信噪比的基础上适当地拓宽地震资料的频带,提升高频端的能量,提高了地震资料的分辨率。更多还原

【Abstract】 In exploration of lithologic-stratigraphic reservoirs, the resolution of seismic data often restricts their identification. High-resolution seismic processing involves severallinks including the key technique-deconvolution. In this study, based on surface consistent deconvolution, wavelet shaping deconvolution is adopted to convert the minimum-phase wavelet into zero-phase wavelet. According to a certain signal-to-noise ratio (SNR), frequency band is widened appropriately to increase the energy of high frequency end and the resolution of seismic data. Those lay the foundation for identification of lithologic-stratigraphic traps.更多还原
