Description

Technical Field

[0001] The utility model relates to the technical field of oil well heat preservation devices, in particular to a hot air heat preservation device for oil wells. Background Technique

[0002] During the process of oil extraction, the heat preservation of oil wells is crucial, especially in cold regions or winter. The temperature of the oil well directly affects the fluidity and extraction efficiency of the oil. If the temperature of the oil well is too low, the oil will become viscous and difficult to flow, resulting in difficult extraction and even possible shutdown of the oil well. Taking effective heat preservation measures is the key to ensuring the stable production of the oil field.

[0003] Traditional oil well heat preservation methods mostly use electric heating tapes or steam heating. Although these methods can provide the necessary heat, there are also some problems. Electric heating tapes have high energy consumption and large operating costs, and their installation and maintenance are relatively complex and prone to failures. Steam heating requires a complete steam supply system, which not only has a large equipment investment but also is complex in operation and difficult to maintain. In recent years, hot air heat preservation devices have gradually received attention. They blow the heated hot air into the oil well through a blower to increase the temperature of the oil well, thereby ensuring the normal flow of the oil.

[0004] The existing hot air heat preservation devices have the following deficiencies:

[0005] 1: The heating pipes of traditional devices are unreasonably arranged, resulting in low hot air heating efficiency and serious energy waste;
