摘要： 静校正是地震资料处理中的一个重要环节,它的存在既影响CDP的叠加效果,也影响地震剖面构造形态的真实性,特别是对低幅度构造,由于构造的时差很小,很容易因为静校正的误差抹杀或伪造一个低幅度构造。为更好地在实际地震资料处理中,特别是在地表复杂地区,解决好静校正这一影响地震资料品质的主要问题,着重论述了各种静校正方法的优缺点、使用前提和条件,通过实例说明如何应用这些静校正方法,更好地解决静校正问题。

Abstract: Static correction is an important link for seismic data processing. To make existed static correction tends to affecting stacking result of common depth point (CDP) and reality of structural feature on seismic profile, for low-amplitude structure, in particular, it is very easy to delete or counterfeit it due to the static corrections. In order to properly deal with the issue affecting seismic data quality in seismic data processing and in complex surface area, this study presents various methods for such static corrections, including advantages and shortcomings, prerequisites or conditions to use. In addition,examples are taken for how to apply these static correction methods so as to better solve the problems occurred in static corrections.

Key words: static correction, micro logging, refraction wave, analog annealing, tomographic image, inversion
