Embodiment：
The utility model provides a kind of petroleum pipeline 100, is sequentially provided with outer tube 1, heat-insulation layer 2, heating tube 3 from outside to inside
With inner tube 4.
Outer tube 1 is steel pipe, can effectively avoid the petroleum pipeline 100 damaged under the collision of external force, prevent because of oil and gas leakage
Cause oil and gas loss and the situation to ambient contamination.
In heating tube 3 is closely coated on by heat-insulation layer 2, heat will be all completely used for inner tube 4 caused by such heating tube 3
Heating, effectively reduce the viscosity of oil gas in pipeline, improve the mobility of oil gas, reduce blocking.
Heating tube 3 is spiral pipe, to the homogeneous heating of inner tube 4 and heating surface (area) (HS it is larger.
In the present embodiment, high temperature and high pressure steam is connected with above-mentioned heating tube 3, because steam cost is relatively low, and draws materials and hold
Easily, if bore chance high temperature associated gas or stratum water, directly it can be conveyed by heating tube 3 together with oil, dropped significantly
Heating cost during low oil-gas gathering and transportation.
Projection is interval with the inwall of inner tube 4, the projection causes the oil gas of flowing constantly to pass through speedup and moderating process,
The viscosity of oil is not only reduced, the oil gas bubble formed during oil gas flowing can be also destroyed, avoid the occurrence of blocking, improve
The mobility of oil gas.
Corrosion-inhibiting coating is equipped with the inwall and projection of inner tube 4, corrosion-inhibiting coating is used for protection inner tube 4 not by the acid in oil gas
Property material corrosion failure, so as to effectively extend the service life of petroleum pipeline 100, reduce the defeated cost of oil gathering.
The both ends of petroleum pipeline 100 are provided with plug.
Operation principle of the present utility model：The heating source of petroleum pipeline 100 provided by the utility model is mainly high temperature height
Steam to be pressed, injects high temperature and high pressure steam from the heating tube 3 of gathering station one end image-stone oil-piping 100, the other end is blocked with plug,
Then the oil in high temperature and high pressure steam and inner tube 4 forms convection current, carries out heat exchange each other, can reduce oil viscosity well,
Improve oil flow.If in some special blocks, when boring chance high temperature associated gas or stratum water, can directly be passed through
Heating tube 3 conveys together with oil, greatly reduces the heating cost during oil-gas gathering and transportation.
The beneficial effects of the utility model are：Petroleum pipeline provided by the utility model uses lamination layer structure, and high temperature steams
Vapour is uniformly heated by heating tube, and heating cost is relatively low, effectively reduces the viscosity of oil in pipeline；It is convex on inner-walls of duct
The oil that rising makes is provided with the characteristic of turbulent flow, and oil flow becomes strong；Erosion shield on inner-walls of duct serves to pipeline
Protective effect, make pipeline not cracky, improve the defeated security of collection, while also extend pipeline service life, save oil gas
Collect defeated cost.
It is described above, not make any formal limitation to the utility model, although the utility model is with preferably real
