APPARATUS FOR PRODUCTION STUDY USING GAS HYDRATE-BEARING SPECIMENS

摘要

PURPOSE: A production testing research device using a boring sample containing gas hydrate is provided to research the production conduct of the gas hydrate by applying vertical and pore stress in a deep-sea sedimentary layer. CONSTITUTION: A production testing research device using a boring sample contained gas hydrate comprises a pressure cell(100), an axial pressurization part, a seawater injection part, a rear pressure control part, and a gas emission measurement part. The pressure cell accepts a boring sample which contains the gas hydrate. The axial pressurization part is equipped with an axial pressure piston(30) to apply vertical stress to the boring sample. The rear pressure control part controls the pore pressure of the boring sample due to seawater injected to the pressure cell. The gas emission measurement part is equipped with a wet gas meter which measures a gas emission rate from a fluid flow port.
