摘要
在全波测量实验中观察到三个现象:1.纵、横波首波幅度绝对值的变化规律相同;2.纵、横波首波的相位始终相反;3.纵、横波首波幅度的变化周期是2_π。本文对这三个现象进行了全面分析与解释,指出相位相反现象应该于全波测井条件下再现,从而为利用相位差异提取全波波形信息找到了依据。
There are three phenomena observed in full wave meassured experiment: 1. the changing rules of the absolute values of the P and S-head waveamplitudes are the same; 2. the phases of the P and S-head waves are opposite all the (?)'with each other; 3. the changing periods of the P and S-head wave amplitus of a soft- This paper gives a fully analysis and interpretation of' (?)(?) V. The softwareomena, and points out that these phenomena should appearocessing part andwave logging condition. So that, the basis of using phase differences toget the information from the full waveforms is found.
