[0002] The main heat preservation objects of the oil well heat preservation box are the Christmas tree and the automatic metering station. Among them, the Christmas tree is a wellhead device used for oil production in flowing wells and rod pumped wells, etc.; the Christmas tree includes tubing hangers, many valves, tees or crossroads, etc., and corresponding protection measures need to be taken. Since the Christmas tree is outdoors, the winter in the northern region is relatively long and the outdoor temperature is relatively low. Therefore, corresponding heat preservation measures must be taken to avoid freezing and cracking of the above-mentioned equipment in winter.

[0003] Hydrogen sulfide is a colorless and highly toxic gas, heavier than air, and easily accumulates in low-lying areas. Hydrogen sulfide is flammable and can form an explosive mixture with air. If the concentration of the mixture gas reaches its explosion limit and encounters ignition sources such as open flames, heat release from chemical reactions, impact or friction sparks, electrical sparks, and static electricity sparks, a combustion explosion accident will occur. Low-concentration hydrogen sulfide has an obvious smell of rotten eggs and can be sensitively detected by people; when the concentration increases, people will have olfactory fatigue or olfactory nerve paralysis and cannot detect the presence of hydrogen sulfide; when the concentration exceeds 1000 mg / m 3 At this time, it can cause lightning-type death to people within a few seconds.
