几种静校正方法的研究与比较

本文针对高程静校正、模型法、沙丘曲线法、折射波近地表校正法、层析反演法以及初至波剩余静校正6种常用的静校正方法做了详细的研究。分别论述了几种静校正方法的原理以及各自的适用范围,研究了每种静校正方法解决问题的能力,探讨了不同的近地表条件下静校正方法适应性和流程,并用3个工区的实际资料,做了几种静校正方法的处理效果对比分析,进一步说明了前述理论成果。

The study and comparison of several static corrections

Six kinds of static corrections,including elevation statics,model statics,dune curve statics,refraction statics,tomography statics and residual statics,are studied and their results are compared against each other in details in the paper. The law and the range of application of each static correction are discussed. The ability of each static correction to resolve problem is studied. The adaptability and work flow of the static correction are discussed under different surface conditions. The results processed by several static corrections are compared to prove the involved laws by using the real data from three areas.
