一、Overview

      It simulates the hydrate sediments’ synthesis and decomposition under the condition of temperature and pressure environment in seabed and the condition of sediment confining pressure. At the same time, it tests the gas-liquid permeability of sand and clay sediments with hydrate at a constant speed or constant pressure.

二、Main technical parameters

1，the maximum working pressure of pressure chamber:30MPa;

2，the temperature control system:-10 to 100℃，accuracy:0.1℃；

3，sample specifications:φ38×800mm;

4，test accuracy of seepage parameters:≥0.5%;
