确定共转换点(CCP)空间位置是转换波资料处理中的基础,在认识到转换波射线路径的不对称性及转换点空间位置是目的层深度、炮检距、纵横波速度及倾角等多参数的函数的特点后,提出了计算CCP空间位置的一种迭代算法,该方法是是一种高效、高精度的方法。根据该迭代算法和目标区的地质构造特点,通过时变、空变划分时窗,设计了CCP定位的转换波处理,通过实例处理,实现了转换波的CCP叠加。
Confirming the location of the CCP is the basis of the converted wave data processing. Recognizing the asymmetry of the converted wave ray path and the space position of the transition point are the depth of the target layer, the offset, the velocity of P- After the characteristic of the function of parameters, an iterative algorithm for calculating the position of CCP is proposed. This method is an efficient and accurate method. According to the iterative algorithm and the characteristics of the geological structure of the target area, the time-varying and space-time partitioning windows are used to design the CCP-oriented converted wave processing. The CCP superposition of the converted wave is realized through the example processing.
