Abstract
The invention discloses a high-temperature-resistant lining oil pipe. The high-temperature-resistant lining oil pipe comprises an oil pipe body, an ultrahigh molecular weight polyethylene lining pipe, an annular steel ring connector and a lining pipe protruding flange. The ultrahigh molecular weight polyethylene lining pipe is mounted under the oil pipe body. The lining pipe protruding flange is mounted on the right side of the ultrahigh molecular weight polyethylene lining pipe. The annular steel ring connector is mounted on the lining pipe protruding flange. A spiral clamping groove is mounted in the annular steel ring connector. By mounting high-performance thermoplastic resin on the lower surface of the ultrahigh molecular weight polyethylene lining pipe, the high temperature resistance of the lining oil pipe is greatly improved, and the influences of the temperature to the lining oil pipe is reduced; by mounting the ultrahigh molecular weight polyethylene lining pipe, the abrasion resistance of the oil pipe body is improved, and the temperature resistance of the oil pipe body is improved; and the oil pipe body is connected with the ultrahigh molecular weight polyethylene lining pipe through a binding reinforcing layer, so that the oil pipe body and the lining pipe is bound more tightly.

Technical field
The present invention relates to liner oil pipe technical field, specially a kind of high-temperature resistant inner lining oil pipe.
Background technology
Oil pipe, is steel pipe that oil field manufacturing enterprise is used in oil, well in a large number, belongs to popular basic production thing
Money.As oilfield development and construction enters High water cut period, the principal element for affecting cost of oil production is short-lived well, producing well oil
The eccentric wear of pipe, corrosion and fouling (rod and tube partial-wear, bar are disconnected, pipe leakage) cause oil well to stop production, the underproduction.Account for because rod and tube partial-wear causes to scrap
Oil pipe year total consumption more than 1/6, cause the huge wasting of resources and production cost to increase.In order to avoid or reduce oil pipe abrasion
The infringement for bringing, using liner tubing as the liner thin layer of conventional oil pipe, improves the antiwear characteristics of oil pipe.But existing liner oil
Often there is non-refractory in pipe, and its structure compare it is simple, go out to exist in the interface of liner oil pipe more serious
Friction problem.
The content of the invention
It is an object of the invention to provide a kind of high-temperature resistant inner lining oil pipe, to solve the resistance to height proposed in above-mentioned background technology
The problem of temperature.
For achieving the above object, the present invention provides following technical scheme：A kind of high-temperature resistant inner lining oil pipe, including it is oil pipe, super

Block, and protruding block is connected with spiral channel, and ultra-high molecular weight polyethylene internal lining pipe, the superelevation are provided with below the oil pipe
Internal lining pipe being installed on the right side of molecular weight polyethylene internal lining pipe and projecting flange, the internal lining pipe to be projected and ring is provided with above flange
Shape steel ring joint, the inside of the annular steel ring joint are provided with spiral channel, and the surface of the annular steel ring joint is provided with
Stainless steel layer.
Preferably, the lower surface of the ultra-high molecular weight polyethylene internal lining pipe is provided with high-performance thermoplastic modeling fat.
Preferably, the oil pipe is connected with ultra-high molecular weight polyethylene internal lining pipe by bonding enhancement layer.
Preferably, the surface of the internal lining pipe protrusion flange is provided with antifrictional chamfering.
Preferably, the surface of the oil pipe is provided with paint timing sprinkler.
Compared with prior art, the invention has the beneficial effects as follows：The present invention is by ultra-high molecular weight polyethylene internal lining pipe
Lower surface be provided with high-performance thermoplastic modeling fat, considerably increase the heat-resisting quantity of liner oil pipe, reduce temperature to its
Affect, by being provided with ultra-high molecular weight polyethylene internal lining pipe, not only increase the wear resistence of oil pipe, also add the anti-of oil pipe
Warm nature, oil pipe are connected with ultra-high molecular weight polyethylene internal lining pipe by bonding enhancement layer so that oil pipe and internal lining pipe are bonded more
Plus it is tight, antifrictional chamfering is installed by the surface of flange is projected in internal lining pipe, it is possible to reduce sucker rod is to superelevation point
The abrasion of sub- weight northylen internal lining pipe, by being provided with paint timing sprinkler, reduces the aging of oil pipe, increases oil pipe and uses
Time.
