| 講演要旨(和文) | | -15℃から25℃までの温度範囲内で部分的に凍結された食塩水、非連結砂と連結多孔性材料で超音波実験が行われた。最初てきに到着する記録パルス波形に基づいて、弾性波の減衰を測定する。実験データを介して、速度と減衰の推定に加えて、違う岩石物理モデルは、速度と気孔率および介在物の弾性率を関連する。異なる岩石の異なる岩石物理モデルの妥当性をテストするために、検査結果は、これらの理論的な予測結果と比較します。 |

| | 講演要旨(英文) | | The ultrasonic wave experiments conducted in partially frozen brine, unconsolidated sands, consolidated porous materials within a temperature range of -15 to 25. Measurements of velocity and attenuation of compressional and shear waves calculated based on the recorded first arrive pulse waveform. In addition to the estimation of velocity and attenuation through experiment data, different rock physics models has been applied to related velocity and attenuation of P- wave and S-wave, extent of freezing, elastic modules of matrix and inclusion in porous medium to porosity. To test the validity of different rock physics models in different rock types, laboratory results compared to these theoretical prediction results. |
