用非线性遗传反演方法进行自动静校正

静校正处理是消除近地层影响的一个重要地震资料数字处理方法，在近地表层纵，横向变化复杂，静校正量变化较大的地区，常规静校正方法和线性反演方法均不能解决问题，遗传算法是近年发展起来的一种模拟生物生化过程的较先进的非线性反演方法，对用遗传算法进行静校正的若干问题进行了讨论，说明它是可以解决表层情况复杂地区静校正问题的一个有效方法。

AUTOMATIC STATIC CORRECTION BY NONLINEAR GENETIC INVERSE METHOD

Static correction is an important processing stage,which corrects the time shift due to near surface parts.In the area where static is greatly changed because of the severe near surface anomalies,traditional and linear inverse techniques can not be applied to calculating the correct statics and so the nonlinear inversion technique should be used.Genetic algorithm is modern nonlinear inversion which simulates biological evolution.Some problems in the static correction with genetic algorithm are discussed.
