Downhole Mentod에 依한 剪斷波의 測定

Abstract

Downhole Method를 利用하여 彈性波의 速度를 測定하였다. 本 論文에서는 剪斷波의 測定에 重點을 두었으며, Cross Correlation을 利用하여 測定한 結果와도 比較 分析하였고, Poission 比도 計算하였다.

In this paper, in-situ elastic wane velocity was measured by the downhole seismic method.

In the analysis of the test, special emphases are given to the identification of the shear wave.

The results of the analysis show that the cross correlation signal analysis reaches the same result as the instantaneous time analysis.

And the Poisson's ratio is also estimated by the wave velocity.
