综合速度与速度的非均质性

Comprehensive Velocity and the Anisotropic Charcter of Velocity

在认识到速度参数对地震勘探开发研究工作重要影响的情况下 ,对速度及其有关的问题进行了包括理论和实际应用等各方面的比较深入的思考 ,探讨了地震波的各种速度的概念及其之间的关系 ,以及在地震勘探开发研究的不同阶段和不同时期对速度参数的不同需求和对速度认识和理解的不断发展 ,指出现阶段应改变用综合速度分析和研究问题的思路 ,采用变速的方法去认知和更加逼近地下实际地质情况 ,以提高研究的精度和勘探开发效益 。

Realizing velocity parameter strongly affects the research work of seismic exploitation and development,the paper discusses more about velocity and other problems concerned theoretically and practically,including the concepts of seismic wave and their relations,velocity parameters required at different stages during different time,pointing out that it is necessary to explore geological situation with a flexible method instead of velocity analysis so as to increase accuracy and efficiency in exploration.At last the paper introduces the velocity analysis on the basis of practical work in Lun-nan region,Tanim Oil Field.\;
