Regarding the ghost reflection the wavelet\'s picking-up and its kinematics and feature and frequency, the characteristics in Kinetics were studied, and the following recognition were obtained:(1)if shot activated under the ghost reflector, the velocity is constant,notch frequency and peak frequency will move to lower frequency with the increase of shooting depth.
文中针对虚反射研究激发子波的拾取及运动学、动力学特点和频率特性,并得出以下认识:①在虚反射界面以下激发,速度值不变,陷波点频率和峰值频率随着激发井深的增加向低频方向移动;②针对高分辨率勘探,要选择较小的调谐深度,可以得到较高的峰值频率;针对深层勘探,可以选择合适的频率所在的调谐深度,在该深度激发可得到能量较强的激发子波。
