在現代的地震勘探中,主要是利用地震波的运动学特点,来勘探地壳的地貭构造的. 地震勘探結果的精确度,在很大程度上与平均速度的选择有关。目前,在我国的很多地区內,深探井較少,速度资料主要还要依靠有效速度的計算来获得.显然,如何根据反射波时距曲綫准确地計算有效速度,仍然是現代地震勘探中的一个重要課題. 目前,已經提出了許多計算有效速度的方法.虽然,这些方法各有其优点,但是,它們 In modern seismic exploration, the crustal structure of the crust is mainly exploited by the kinematics of seismic waves, and the accuracy of the seismic exploration results is largely related to the choice of average velocity. At present, in many areas in our country, there are fewer deep exploration wells, and the velocity data mainly depend on the calculation of the effective velocity. Obviously, how to accurately calculate the effective velocity based on the reflection time-curve is still one of the modern seismic exploration An Important Problem Currently, many methods for calculating effective velocity have been proposed and although these methods each have their own advantages, they
