本文重点阐明了符号位相关速度谱,速度的自动拾取及自动实现真振幅叠加、符号位叠加的理论和实践。实验表明,针对符号位相关谱的特点,采用模糊数学的基本理论,综合多种检测方法,即可简捷灵活,极其近似地模拟人工解释速度谱这一过程,从而自动提取速度参数,完成水平叠加处理和其它一些处理。同时可输出速度剖面,使速度的纵横向变化一目了然。符号位处理成功,展现了以高复盖次数、高采样率的全符号位接收和处理,迅速提高地震勘探精度和分辨率的光辉前景,同时也为实现更广泛的以综合解释为目标的反复自动处理准备了条件。
This article focuses on the symbol bit-related speed spectrum, the speed of automatic pick-up and automatically realize the real amplitude superimposition, symbol bit overlay theory and practice. Experiments show that, based on the characteristics of the sign bit correlation spectrum, the basic theory of fuzzy mathematics and the combination of multiple detection methods can be used to simulate the process of manually interpreting the speed spectrum by combining a variety of detection methods, thus automatically extracting the speed parameters and completing the horizontal superposition Processing and some other processing. At the same time can output speed profile, the speed of vertical and horizontal changes at a glance. The success of the sign bit processing shows the brilliant prospect of receiving and processing at full sign bits with high overlay times and high sample rates to rapidly increase the accuracy and resolution of the seismic exploration and also to achieve a wider iteration with the goal of comprehensive interpretation Prepared for automatic processing conditions.
