The device disclosed by the invention has the characteristics of reasonable structure, ingenious design, operational flexibility, accuracy in measurement and the like.

Description

technical field [0001] The invention relates to a safety evaluation device for simulating fluid flow in oil and gas pipelines. The invention belongs to the technical field of oil and gas pipeline fluid flow safety assurance. Background technique [0002] In oil and gas pipelines, pipeline blockage caused by hydrates and wax deposition and safety issues caused by pipeline corrosion will cause safety accidents. In addition, in the low-temperature and high-pressure environment of the deep seabed and deep sea, gas pipelines are also very easy to block due to the formation of hydrates and cause safety accidents. As the exploitation of deep-sea natural gas has been paid more and more attention, the requirements for deep-sea gas production technology have been further increased, and higher requirements have been put forward for the safety of deep-sea gas production.

AI Technical Summary

Problems solved by technology

[0003] The 2010 U.S. Gulf of Mexico crude oil spill was due to the failure of the sealing of the oil pipeline due to the existence of a methane bubble, which eventually caused the "Deepwater Horizon" drilling platform in the Gulf of Mexico to explode and cause a fire, resulting in a series of economic losses and environmental pollution

Scholars from various countries have established many multiphase fluid transport safety experimental devices, such as the French IFP-lyre loop, the Archimede flow loop, and the ExxonMobil experimental loop. These loops have such novel designs as , easy operation, etc. Although some scientific experimental data can be obtained by using these loops, it is far from enough to evaluate the safety of fluid flow.
