Description

technical field [0001] The invention relates to a heating system for oil field sewage, in particular to a heating system for externally transporting crude oil with residual heat of oil field sewage. Background technique [0002] Oil fields produce a large amount of oily sewage in the production process, and the waste heat of these oily sewage is discharged into the atmosphere, which causes thermal pollution and wastes resources. On the one hand, as the development of oil fields enters the middle and later stages, the amount of oily sewage water in oil wells is increasing; on the other hand, dehydration and transportation of crude oil require heating, especially heavy oil, which must be heated to reduce the viscosity due to its high viscosity. It can be exported after sticking. The heavy oil gathering and transportation process mainly includes three processes: hot water mixing, thin oil mixing and three-pipe heat tracing. The corresponding heating furnaces are also divided ...
