地震波的速度是地震勘探中的一个重要参数,在地表及地下地质构造复杂地区,如何求取的准确的地下介质速度将直接影响到动校正、叠前或者叠后偏移、剩余静校正量等,因此获取准确的速度参数是正确处理和解释地震资料的关键问题,本文运用多种速度分析方法对速度数据进行质量控制,力求速度场的精准度和合理性。
The velocity of seismic wave is an important parameter in seismic exploration. How to find out the accurate velocity of underground medium will directly affect the dynamic correction, prestack or poststack migration, residual static correction and so on in surface and subsurface geological complex areas Therefore, obtaining accurate velocity parameters is the key issue for the correct processing and interpretation of seismic data. In this paper, a variety of velocity analysis methods are used to control the velocity data to seek the accuracy and rationality of the velocity field.
