Description

technical field [0001] The invention relates to a process for simulating the formation, migration and deposition of multi-component gas hydrates in high-pressure and high-speed airflows, and observing the interaction between airflows, gas hydrate particles, and gas hydrate particles in pipelines at various angles Visual dynamic simulation device for gas hydrate pipeline deposition. Background technique [0002] During the exploitation and transportation of natural gas, the formation of natural gas hydrate often blocks gas wells and surface pipelines. When natural gas is under high pressure, hydrates can be formed even at room temperature. During the transportation of natural gas, the undulations of the terrain will lead to liquid accumulation in the recess of the pipeline and the formation of local throttling, which will aggravate the formation of natural gas hydrate. The deposition of natural gas hydrate in production facilities greatly reduces the utilization rate of pro...
