Abstract
It's very important to control the sensors of ultrasonic and Time Domain Reflectometry when study the relationship between gas hydrate saturation and acoustic parameters in sediments. We combined Ultrasonic Wave and Time Domain Reflectometry in one apparatus to study the acoustic parameters of gas hydrate-bearing sediments in different saturation. The experimental results show that the apparatus is well designed and can work smoothly. Subsequently, we compare the calculated data by time-average equation, Woods equation, Lees weighted equation and Biot-Gassmann Theory by Lee (BGTL) with the observed data in experiments. It suggests that the Lees weighted equation and BGTL are more applicable in our experiments and various sediments.
