【摘要】 为解决近地表速度异常和地形起伏引起的静校正问题,已出现了多种静校正方法,这常常使资料处理人员无所适从。这里从众多的静校正方法中选择了三个具有代表性的,在生产中用得较多的方法(折射静校正、无射线追踪层析静校正、非线性层析静校正),从方法原理、方法特点、实际应用效果等方面进行了比较研究,最后给出了针对不同目标选择适当静校正方法的建议,以帮助资料处理人员在实际资料处理中,有针对性地选择静校正方法,快速有效地完成资料处理任务,提高处理质量。更多还原

【Abstract】 There are various methods to deal with the statics correction problem in the complicated region and seismic data processors are often puzzled.This paper research the three representative statics correction methods(Refraction statics correction,Tomo-Statics without ray tracing,nonlinear Tomo-Statics) from the points of principle、characteristics、 practical effects.Finally,the paper proposes some suggestions to help the seismic data processor to choose reasonable approach to complete seismic processing efficaciously and to improve the processing quality.更多还原
