理论上,垂直地震剖面(VSP)可以提供许多与地下有关的信息(层速度,反射系数,吸收,多次反射波,倾角,地面地震资料处理中应用的反褶积算子的决定,波转换的范围,当在同一口井中记录 P 波和 S 波的 VSP 时,P 波同相轴和 S 波同相轴的相互关系,泊松比等)。实际上获得这些结果不仅仅要根据信噪比,还要根据一些数据采集的参数和处理程序及其应用。数据采集中最重要的参数是测站间的距离和带宽,因为在应用频率一波数滤波器时,这些参数对处理阶段的假频现象起支配作用。如果我们想研究振幅和检验每一道的时间原点,记录近场的特征波形是很重要的。要想在所有道上很好地确定上行波,那么在记录时就必须大大地对管道波进行衰减;为了减少管道波的振幅,检验井中的泥浆层和震源位置对于记 In theory, the VSP can provide many subsurface-related information (layer velocity, reflection coefficient, absorption, multiple reflections, dip, decision of deconvolution operators used in terrestrial seismic data processing, wave conversion , The correlation between P-wave events and S-wave events, Poisson’s ratio, etc.) when P-wave and S-wave VSPs are recorded in the same well. In fact, these results are not only based on the signal-to-noise ratio, but also on some data acquisition parameters and processing procedures and their applications. The most important parameter in data acquisition is the distance and bandwidth between stations since these parameters dominate the aliasing in the processing phase when applying the frequency-one-wave filter. If we want to study the amplitude and test the time origin of each track, it is important to record the characteristic waveforms of the near-field. To determine the upwelling well well on all tracks, the pipeline wave must be greatly attenuated at the time of recording; in order to reduce the amplitude of the pipeline wave, it is necessary to examine the mud and hypocenters in the well
