| 要約: | Acoustic laboratory measurements have been conducted for forty-two sandstone samples at fully air and water saturation. This study is an attempt to learn more about the behavior of both P-wave and S-wave velocity in porous sandstone rock samples for both dry and wet conditions.
The statistical analysis indicates that higher values of the P-wave velocity are obtained for saturated samples and lower values are obtained for dry samples. The average P-wave velocity of dry rock samples is 2766 m/s and the average P-wave velocity of wet rock samples is 2950 m/s. The S-wave velocity is higher in the dry state with an average value of 1585 m/s. The average S-wave velocity of wet rock samples is 1357 m/s.
The derived equations can be used for the prediction of P-wave velocity of wet rock samples from the P-wave velocity of dry rock samples, and the S-wave velocity of wet rock samples can be predicted from the S-wave velocity of dry rock samples. A strong linear correlation between P-wave velocity and S-wave velocity of dry rock samples and between P-wave velocity and S-wave velocity of wet rock samples was found. The resulting linear equations can be used for the estimation of S-wave velocity from the P-wave velocity in the case of both dry and wet rock samples. |
