Measurement of Thermal-Physical Parameters of Gas Hydrate in Porous Media
-
ABSTRACT
Based on the time domain reflection technique and transient hotwire thermalphysical measurement technique, a gas hydrate experimental equipment has been designed to measure the thermalphysical properties of gas hydrate in porous media under high pressure. Hydrate is synthesized in porous media which particle size is between 0.18~0.25 mm, and 0.3 g/L sodium dodecyl sulfate (SDS) is added into the system as surfactant. The gas source is methane (99.9%). The thermalphysical properties of hydrate were detected in the sediment layers. The heat conduction rate measured by cross hotwire method is (1.112±0.080) W/(m·K) and the result measured by parallel hotwire method is (1.078±0.057) W/(m·K).
