Title:
HYDRATE-CONTAINING STRATUM HEATING SETTLEMENT SIMULATION EXPERIMENT DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/000834
Kind Code:
A1
Abstract:
A hydrate-containing stratum heating settlement simulation experiment device and method, the device comprising: a reaction container (1) configured having a reaction cavity (101); a pressurizing assembly (2) and a temperature control assembly (3) which are connected to the reaction container (1) and used for regulating the pressure and temperature in the reaction cavity (101) respectively; a confining pressure assembly (4) surrounding the sidewall of the reaction container (1) and used for adjusting the confining pressure in the reaction cavity (101); an electric heating pipe (5), vertically arranged at the bottom of the reaction cavity (101) and extending upward to be inserted into hydrate, wherein the electric heating pipe is provided with a hollow channel, and meshes communicating with the hollow channel are formed in the side wall thereof; a collecting and measuring device (6), communicating with the electric heating pipe (5) and used for collecting and measuring the amount of gas, liquid and solid generated after the hydrate melts; and a control module, connected to the pressurizing assembly (2), the temperature control assembly (3), the confining pressure assembly (4) and the collecting and measuring device (6). The hydrate-containing stratum heating settlement simulation experiment device and the method may acquire the change rule of the amount of the hydrate decomposing gas, liquid and solid and the stratum settlement amount within different heating ranges and under different heating temperature conditions.
