Description

Technical Field

[0001] The utility model relates to the technical field of oilfield oil well pipeline heating equipment, in particular to an integrated high-efficiency air source heat pump oilfield oil well pipeline heating unit. Background Art

[0002] In traditional oilfield well pipeline heating systems, electric heaters and gas-fired heating boilers are usually used as the main heating solutions;

[0003] However, these methods have obvious disadvantages, because the heating systems of electric heaters and gas boilers are quite complicated, resulting in high energy consumption and increased cost expenditure. Although some oilfield oil well pipeline heating systems use conventional air source heat pump heating systems, this heating method also has some problems. On the one hand, its system connection is relatively complicated, which brings inconvenience to operation and maintenance. On the other hand, due to the low temperature of air source heating, the oil circulation outlet temperature is also low, which affects the oil supply efficiency.

[0004] In addition, the current pump sets are all installed in separate parts on site. Manufacturers need to transport multiple equipment supporting the pump sets to the destination separately and install them centrally at the destination. This not only requires the manufacturer to send specialists to carry out on-site installation, but also requires users and manufacturer installation personnel to cooperate on site for a long time, which is time-consuming.

[0005] Therefore, in order to improve the efficiency and effect of the oil field oil well pipeline heating system, it is necessary to improve and optimize the existing heating system. Utility Model Content
