A series of technical problems occurred in production.
Therefore it provides the multi-functional core layer foaming complex heat-preservation abrasion-proof oil conduit such as a kind of wear-resisting, anti-corrosion, heat-insulated is this field
The problem of technical staff's urgent need to resolve.
Utility model content
In view of this, the present invention provides a kind of core layer foaming complex heat-preservation abrasion-proof oil conduits, can not only prevent oil
The eccentric wear and corrosion phenomenon of well rod tube, and can be effectively reduced dissipating for heat during crude oil is given rise to well head from shaft bottom
It loses, improves viscosity, wax deposition and the fluidised form of crude oil in the wellbore, realization improves wellhead temperature in actual production, reduces production energy
Consumption and cost.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of core layer foaming complex heat-preservation abrasion-proof oil conduit, including oil pipe, it is multiple that the inside of the oil pipe has been lining into core layer foaming
Close pipe；The core layer foaming multiple tube includes outer layer, internal layer and middle layer；The outer layer is connect by the middle layer with the internal layer
It is integral, the inner wall of the outer layer and the oil pipe fits closely.
By taking above scheme, the beneficial effects of the utility model are:
By entering core layer foaming multiple tube in oil tube inner lining, the overall structure of " tube-in-tube " is formd, core layer foaming is compound
Pipe not only has thermal insulation property, also has the function of eccentric abrasion prevention, anticorrosion and pressure resistance.
Further, the outer layer and the internal layer are high-density polyethylene plastics pipe or ultra-high molecular weight polyethylene modeling
Expects pipe.
Advantageous effects by adopting the above technical scheme are that internal layer is high-density polyethylene plastics pipe or supra polymer
Weight northylen plastic tube can prevent the rod and tube partial-wear generated when oil well operation and corrosion phenomenon；Outer layer is high density or superelevation
Molecular weight polyethylene plastic tube, the elasticity after necking down tube restore function and core layer foaming multiple tube are integrally firmly fitted in
In oil pipe, it can prevent core layer foaming multiple tube from deviating from out of oil pipe.
Further, the end of the internal layer is turn-up portion, and the turn-up portion extends the outer layer and the middle layer, and
And the turn-up portion is fitted on the end face in the outer layer and the middle layer.
Advantageous effects by adopting the above technical scheme are that it is multiple that turn-up portion can prevent liquid from penetrating into core layer foaming
It closes in pipe and reduces heat insulation effect.
Further, the middle layer is heat-insulation foam material.
Further, there is microcellular structure on the middle layer.
Advantageous effects by adopting the above technical scheme are that the microcellular structure that the foamed technique in middle layer is formed can increase
Add thermal insulation property.
Further, the oil pipe includes the first oil pipe and the second oil pipe, and first oil pipe passes through box cupling and described the
The connection of two oil pipes.
Further, the box cupling has been embedded in seal rubber sleeve.
Advantageous effects by adopting the above technical scheme are, by seal rubber sleeve, can guarantee to connect between oil pipe
Leakproofness.
It can be seen via above technical scheme that compared with prior art, the utility model, which discloses, provides a kind of sandwich layer hair
Complex heat-preservation abrasion-proof oil conduit is steeped, there is wear-resisting, anti-corrosion, heat-insulated and insulation effect, it is inclined to solve rod tube present in flow string
Mill, inner tube pressure resistance, oil pipe internal corrosion, tubing wax fouling, thermal well flushing problem improve pit shaft and Wellhead crue oil outlet temperature
Degree improves crude oil fluidised form in the wellbore, reduces pumping unit load, reached energy-saving and emission-reduction, increased production and improved productivity, substantially reduce
The effect of cost of oil production.
