为提高地震约束反演及相干去噪时相邻道间相关分析的精度，首次提出了一种新的相干扫描分析方法。在扫描时使用变化的时窗长度和时窗端点，通过加权求和扫描寻优，实现了包括反射波组平移、伸缩、增减等多种变化情形在内的复杂道间关系的描述。该方法为约束反演时，通过横向外推获得无井地震道的约束条件提供了更加精确的方法。对模型数据和实际资料的处理结果都证明了该方法的正确性和实用性。
For the first time, a new coherent scanning method is proposed to improve the accuracy of correlation analysis between adjacent constrains when seismic inversion inversion and coherent de-noising. The time window length and the window end point are used in scanning, and the weighted summation scanning is used to optimize the description of the complex channel including the variation, such as the translation, expansion and contraction, increase and decrease of the reflected wave group. This method provides a more accurate method for constraining non-well seismic traces by lateral extrapolation when constraining the inversion. The results of model data and actual data prove the correctness and practicability of this method.
