静校在地震反射法中起着重要的作用,尤其在陆地浅层地震反射勘探工作中,它可以改善反射层的横向连续性.为了计算静校值,在风化层和其以下的基岩地层界面之间,我们使用初至折射时间.现在假设射线传播时间由炮点高程、接收点高程、构造项和误差项的总和构成.这些项在最小二乘法意义上是一组线性联立方程解。这些方程是病态的,并且有发散趋势,然而,引入一个阻尼参数压制发散,我们可以用迭代形式解这些方程。这种方法只使用反射地震记录,这是一种很简单和有效的方法.
Static school plays an important role in the seismic reflection method, which can improve the lateral continuity of reflector especially in the shallow seismic reflection exploration of the terrestrial.In order to calculate the static calibration, We use the first refraction time between the interfaces Now suppose that the ray propagation time consists of the sum of the shot elevation, the reception point elevation, the construction term, and the error term These terms are, in the sense of least squares, a set of linear simultaneous equations . These equations are pathological and have divergent trends. However, by introducing a damping parameter to suppress divergence, we can iteratively solve these equations. This method uses only reflective seismic records, a very simple and effective method.
