The New Technology by Using Multiple Wave Calculate Reflection Coefficient
-
摘要: 传统地震资料处理将多次波视为干扰波进行压制,而多次波是有效波在地层中来回传播的反馈,因此它携带了地层反射系数信息。本文从多次波成因出发,推导出反射系数公式(反射系数等于一阶多次波与一次反射波的反褶积)。理论模型实验证明了该方法的正确性。对实际海洋单道地震资料进行处理,求取的反射系数与有效波基本吻合,但由于资料信噪比、子波及反褶积算法等局限性,该技术有待进一步研究。Abstract: Conventional seismic data processing will be suppressing multiple waves as interference wave. Multiple waves are the feedback of reflected wave spread in the formation back and forth, so it carries information of reflection coefficient. Base on the causes of multiple waves, this article deduces reflection coefficient formula, that is the deconvolution of the first order multiple wave and the reflected wave. The theoretical model shows that the method is correct. The reflection coefficient is matched roughly with the reflected wave in processing of single channel seismic data. Because of the limitations of SNR, wavelet and deconcolution algorithm, this method needs further research.
