Mobile natural gas hydrate evaluation device

Abstract

The invention discloses a movable natural gas hydrate evaluation apparatus. The apparatus comprises a temperature field device, a natural gas injection pipeline, a natural gas outflow pipeline and a component water injection pipeline; the temperature field device comprises a temperature field tank and a refrigerating unit; an internal coil pipe is arranged in the temperature field tank; the temperature field tank is respectively connected with the refrigerating unit and an acquisition processor; the sidewall of the temperature field tank is provided with a visual window; the natural gas injection pipeline is connected with the internal coil pipe; the natural gas outflow pipeline is connected with the internal coil pipe; and the water injection pipeline is connected with the natural gas injection pipeline. The movable natural gas hydrate evaluation apparatus can be used to evaluate and research hydrate formation conditions and additives in the exploitation field of natural gas, and has the advantages of convenient transportation, convenient operation and strong applicability.

Description

technical field [0001] The invention relates to a mobile natural gas hydrate evaluation device, which belongs to the field of petroleum and natural gas. Background technique [0002] Since the 1990s, with the gradual deepening of people's understanding of gas hydrate, gas hydrate, as an important strategic resource and a potential geological environment influencing factor, has been deeply and comprehensively studied all over the world. Undoubtedly, laboratory-scale simulation experiment research is an important part of it. At present, hydrate research methods show interdisciplinary and interdisciplinary application characteristics, and a large number of novel technologies and methods have been applied to hydrate research. , there are three main approaches: direct application in in-situ testing devices; using modern testing techniques to study hydrate samples; transforming testing instruments to make them suitable for in-situ testing of hydrates. [0003] Natural gas hydrate...

AI Technical Summary

Problems solved by technology

In severe cases, some hydrates can block wellbores, pipelines, valves and equipment, thereby affecting the normal operation of natural gas exploitation, gathering, transportation and processing, which is very harmful to oil and gas production, storage and transportation

[0004] At present, the hydrate inhibitor technology has only been tested in the laboratory, and there is no field experiment experience
