克希霍夫积分法偏移讨论

A DISCUSSION ON KIRCHHOFF SUMMATION METHOD OF MIGRATION

克希霍夫积分法偏移在国外已广泛用于处理地震资料.但在国内对此法的应用和讨论均较少.文献[1]介绍了原理及计算方法,方献[2]对其原理作了详细的讨论,本文的目的是在[1]和[2]的基础上,对该方法的原理和算法上的简化作进一步的探讨,指出了采用简化算式的合理性和可能性.

It is true that Kirchhoff-summation method of migration has been widely used in the field of seismic data processing abroad whereas its scope of application and discussion are, to some extent, limited at home and not so many geophysicists have interest for it as overseas do. Its principles and way of calculation are introduced in LITERATURE[1] while its principles are comprehensively expounded in LITERATURE[2]. What this paper aims at is, based on [1], [2], fundamentals of the method mentioned as well as ,the simplification on algorithm are put forward. Moreover, the reasonablenessand feasibiliy of applying the formular simplified are verified.
