Computation of Gas Hydrate Saturation Models Based on The Experimental Acoustic Parameters
It is necessary to know gas hydrate saturation in evaluating gas hydrate volume. So far,there are only few models to estimate gas hydrate saturation. These models are often empirical or derived from observed data. Therefore,we need to confirm their legitimacy and get an approach to use the correct model For the first time,we combine Ultrasonic Wave and Time Domain Reflectometry to study the relationship between gas hydrate saturation and acoustic parameters,which gets fine results. Subsequently,it attempts to compare the calculated data by time-average equation,Woods equation,Lees weighted equation and BGTL with the observed data in experiments. The results show the experimental method is very effective. It suggests that the Lees weighted equation and BGTL are more applicable in our experiments and various sediments.
