速度分析方法研究是现代地震勘探的重要课题之一。本文探讨在常规速度分析基础上发展起来的一种新方法:密点速度分析。 本文首先讨论密点速度分析的原理和实现,绘出其一般处理流程框图。进一步讨论和这一方法的效果有关的问题,指出该方法较之传统方法具有一定优点。最后用实际资料试算验证理论分析,同时指出这类方法在应用上的某些局限性。 处理效果表明,该方法提供了一种速度分析的实用手段。它适用于较高精度叠加,并有可能进一步用于速度分析的其它方面。
Research on velocity analysis method is one of the most important topics in modern seismic exploration. This article explores a new method developed on the basis of conventional velocity analysis: the velocity of the dense point. This paper first discusses the secret speed analysis of the principle and implementation, draw the general process flow diagram. Further discussing issues related to the effectiveness of this method, pointing out that this method has some advantages over traditional methods. Finally, the actual data trial verification theory analysis, and pointed out some of the limitations of this method in the application. The processing effect shows that this method provides a practical means of speed analysis. It is suitable for higher precision overlays and may be used further for other aspects of speed analysis.
