Description
Technical field
It the utility model is related to pipeline field, and in particular to a kind of thermal insulation tubing.
Background technology
The oil production method of domestic each elephant is either any at present, during fluid is from oil reservoir to ground, temperature
Decline very greatly, and viscosity increase is very big, in addition to a small amount of heat extraction by steam injection or electrical heating thermal recovery can guarantee that oil well oil outlet temperature,
Crude oil from during oilbearing stratum rises to ground, the temperature of crude oil substantially slightly above with the formation temperature of position, from
55-130 DEG C during oil reservoir drops to 15-30 DEG C, and many oil wells are because yield is smaller, during winter production, when fluid reaches ground well head
Temperature only at 15 DEG C~20 DEG C, far below freezing point (crude oil freezing point is typically at 30 DEG C~38 DEG C), and crude oil is in underground
The viscosity (thin oil) of oil reservoir is typically at 4~5mpa.s (close to the viscosity of edible salad oil), from this, crude oil carries in oil pipe
Viscosity adds more than several times during rising, in many cases the viscosity of fluid to ground be its in oil reservoir 9 times of viscosity with
On, and oil liquid temperature reduces the increase for causing viscosity, makes frictional resistance increase of the fluid in pipeline, it is therefore desirable to bigger takes out
Oil machine power consumption maintains to produce, moreover, the increase of viscosity directly results in the flow resistance increase of fluid, when fluid is to ground,
Mobility has been deteriorated, and generally requires hot water with defeated, causes resource with collecting the waste of defeated expense.
