浅层折射波勘探中确定覆盖层速度的一种方法

在对浅层折射波勘探资料的解释中,覆盖层速度是极其重要的参数。本文提出了一种结合钻井深度资料来计算覆盖层速度的新方法,并对这种方法的精度和稳定性给予了较详细地讨论。最后通过对几个模型的计算,证明了这种方法是很可靠的。

A METHOD FOR DETERMINING COVERAGE VELOCITY INTHE SHALLOW REFRACTION WAVE EXPLORATION

The coverage velocity is an extremely important parameter in the inter-pretation of shallow refraction wave exploration data. This paper presents a newmethod for calculating coverage velocity which takes into account data of dril-ling depth, and gives a rather detailed discussion on the precision and stabilityof this method. The calculations on several models demonstrate the reliabilityof this method.
