均方根速度

根据地震勘探中的CDP资料，可以提取每个反射层的平均速度、层速度以及均方根速度，利用这些速度参数可以预测地层压力和计算钻井用的泥浆比重。

The average velocity , interval velocity and RMS velocity of each layer can be obtained from seismic CDP data . They may be used to predict formation pressure and to calculate the specific gravity of drilling mud .

本文完成的工作主要有以下几个方面：1.论述了几种常用地震波速度的定义，如平均速度、层速度、均方根速度及叠加速度，并总结了它们之间的联系。

用修正后的模型计算出的平均速度分布、均方根速度的分布以及雷诺应力的分布，均与直接数值模拟（DNS）的结果吻合较好。

The mean velocity profiles , the RMS ( root-mean-square ) velocity profiles and Reynolds stress profiles calculated by the modified model are consistent with the results of DNS .

导出深度域中均方根速度与层速度之间的关系；

The relationship between stack velocity and interval velocity was deduced in depth .

如果使用均方根速度代替单一地层速度，这个双曲线公式可以被推广到多层反射。

If equivalent velocity is considered , this equation can be extended to fit multi-interfaces reflections .

因此，获得的速度分析结果低于介质的均方根速度。

As a result , the velocity calculated is lower than the root mean square velocity of media .

由于多次波包含了一次反射波的速度信息，因此，凡提取到相同均方根速度时，其时间滞后的反射波必是多次反射波。

The information about the velocity of the primary reflection is included in that of the multiple reflection . The time-lag reflections which have the same root-mean-square velocity must be multiple reflections .

本文依据反射波理论双曲线方程，提出了一种通过判别检测到的均方根速度的方法来鉴别全程多次波，并自动检测一次反射波。

Based on the theoretical reflection hyperbolic equation , a new method is proposed in this paper for auto-determination of the primary reflection and auto-differentiation of the multiple reflection by distinguishing the detected root-mean-square velocity .

为了得到较好的动校正效果，必须进行三参量速度分析，确定地下反射界面的三参量速度信息，即倾向、倾角和均方根速度。

In order to achieve good dynamic correction , we must do three-parameter velocity analysis , namely determination of three-parameter velocity informations of subsurface reflector : dip direction , dip angle and mean square-root velocity .
