Heat insulated building for heavy oil well

Abstract

The invention discloses a heat insulated building for a heavy oil well. According to the heat insulated building for the heavy oil well, a brick-concrete arched over house body is built outside a heating furnace; a flame burner of the heating furnace is arranged outside the brick-concrete arched over house body; a heating furnace chimney extends out of a roof of the brick-concrete arched over house body; a steel frame color plate mobile house body is arranged outside a heavy oil well Christmas tree; a single leaf door is mounted at one part, right ahead and corresponding to the heavy oil wellChristmas tree, of the steel frame color plate mobile house body; a passage for a polished rod and a polished rod sealing device to pass through is formed in the roof of the steel frame color plate mobile house body; the steel frame color plate mobile house body is docked and sealed together with the brick-concrete arched over house body; the steel frame color plate mobile house body and the brick-concrete arched over house body seal and cover the heating furnace, a pipeline and the heavy oil well inside; lifting rings are arranged on the roofs of the steel frame color plate mobile house bodyand the brick-concrete arched over house body; and a flame-retardant is arranged inside the brick-concrete arched over house body. As a mode of using the steel frame color plate mobile house body andthe brick-concrete arched over house body to seal and cover the heating furnace, the pipeline and the heavy oil well inside is adopted, the heat insulated building for the heavy oil well disclosed bythe invention has the advantage that the heat insulated effect of the heavy oil well is good in winters.

Description

Technical field [0001] The invention relates to the technical field of heat preservation of heavy oil wells in winter, in particular to a heat preservation room for heavy oil wells. Background technique [0002] In the existing production of heavy oil wells, the most critical production technology is to heat and heat the heavy oil wells. At present, the insulation of oil well Christmas trees, heating furnaces, and double-pipe processes is achieved by wrapping insulation materials such as felt, glass cloth, and paint. Even so, in winter, there are still some heavy oil wells that are difficult to withstand the low temperature around -20℃, and are forced to stop production accidents caused by freezing and blocking of oil and gas pipelines, set pressure gauges, back pressure gauges, sampling valves, constant pressure valves, etc. The freeze-blocking failure of heavy oil wells will not only hinder the production of heavy oil wells and real-time monitoring of heavy oil wells, but also...

AI Technical Summary

Problems solved by technology

Even so, in winter, some heavy oil wells are still hard to withstand the low temperature of around -20°C, and they are forced to stop production due to freezing and blocking of oil pipelines and gas pipelines. Casing pressure gauges, back pressure gauges, sampling valves, constant pressure valves, etc. This not only delays the oil production of heavy oil wells and real-time monitoring of heavy oil wells, but also poses the risk of accidental injury to personnel due to the handling of production shutdown accidents; at the same time, heavy oil wells need to be demolished and kept warm for every pump inspection and other operations In addition, oil wells are exposed to the wilderness, which is likely to cause illegal and criminal problems such as oil theft, gas theft, and theft of facilities.
