Title:
HYDRATE EVALUATION EXPERIMENT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/000891
Kind Code:
A1
Abstract:
Disclosed are a hydrate evaluation experiment system and a method therefor. The evaluation experiment system comprises a first gas cylinder (1), a second gas cylinder (2), a flow control device, a flow controller (12), a magnetic stirring vessel (63), a chemical reagent injection device, and a closed loop, wherein the first gas cylinder (1) is used for storing CH4 or a natural-gas mixed gas; a gas outlet of the first gas cylinder (1) is connected to the magnetic stirring vessel (63) via the flow controller (12); the second gas cylinder (2) is used for storing CO2 gas; a gas outlet of the second gas cylinder (2) is connected to the magnetic stirring vessel (63) via the flow control device; a chemical reagent injection port is provided on the magnetic stirring vessel (63), and the chemical reagent injection port is connected to an outlet of the chemical reagent injection device; and the closed loop is respectively connected to the first gas cylinder (1), the second gas cylinder (2) and the chemical reagent injection device by means of a twentieth valve (42). According to the invention, hydrate formation can be simulated, and the influence on the hydrate formation and decomposition rules is also analyzed, facilitating the conduction of further detailed analysis and research, thereby guiding production.
