英文摘要 | 本文提出了基于测井、VSP和地震数据拟合的子波估计方法,从输入输出都包含随机噪声的统计模型出发,采用相关性拟合技术来提取子波。拟合度和误差分析为整个过程提供了定量的质量控制手段,可以评估数据拟合和子波估计的可靠性。实际数据试算表明,该方法在含有噪声的实际数据中稳定而有效,在地震频带内的子波估计和数据拟合是可靠的。该方法无需对子波相位和振幅谱进行任何假设,其主要优点在于确定相位的能力。; In this paper, we present a method of wavelet estimation by matching well-log, VSP, and surface-seismic data. It's based on a statistical model in which both input and output are contaminated with additive random noise. A coherency matching technique is used to estimate the wavelet. Measurements of goodness-of-fit and accuracy provide tools for quality control. A practical example suggests that our method is robust and stable. The matching and estimation of the wavelet is reliable within the seismic bandwidth. This method needs no assumption on the wavelet amplitude and phase and the main advantage of the method is its ability to determine phase.; SCI(E); 0; 04; 384-391+401; 7 |
