Abstract
The utility model discloses a composite oil pipe with an anti-corrosion wear-resistant inner lining. The composite oil pipe comprises an outer pipe, an inner pipe of which the length is larger than the outer pipe is fixedly embedded into the outer pipe, two end surfaces of the inner pipe protrude out the end surface of the outer pipe, the inner pipe is a thermoplastic high-density polyethylene composite pipe or an ultra-high molecular weight polyethylene composite pipe with wear-resistant, corrosion-proof, paraffin-proof and anti-scaling performances, and the two end surfaces of the outer pipe are wrapped in the outer wall of two ends of the inner pipe. According to the utility model, as the wear-resistant, anti-corrosion, paraffin-proof and anti-scaling thermoplastic high-density polyethylene composite pipe or the ultra-high molecular weight polyethylene composite pipe is fixedly embedded into the outer pipe to serve as the inner pipe, the oil pipe adopting an integral structure is formed. Under the premise of not losing mechanical properties, the oil pipe is endowed with favorable wear-resistant, anti-corrosion, paraffin-proof and anti-scaling performances and is prolonged in service life, unnecessary rework operation is omitted, the working efficiency is improved, and the oil production cost is lowered.
Description
Technical field
The utility model relates to a kind of wear-and corrosion-resistant pipeline for the use of fields such as oil field, chemical industry, power plant, colliery, can be widely used in pipelines such as oil/water well injection-production column jacket and oil-gas gathering and transportation, water filling, chemical industry, be to grow up in recent years transfer line and flow string are carried out the new technology that wear-and corrosion-resistant is handled.
Background technique
People were coated with at the plain tubing internal surface the interior anticorrosion common employing of oil pipe and coated early stage, made oil pipe have the wax control antiseptic property.Because rust cleaning is clean and coating is thinner in the oil pipe, coating can peel off disengaging gradually in the using process of oil pipe, and breaks away from the coating impurity that falls and also can cause down-hole accident to take place, and needs to carry out often workover eration for this reason.Simultaneously, existing coating tubing does not have wear-resisting property.For solving wear-resisting problem, adopted technology such as glass-lined, antifriction metal (AFM) liner, anti-eccentric wear well head in the past, it is frangible that glass-lined pipe exists, the wearing and tearing of broken back and anticorrosion aggravation, effective date is short, anticorrosion antiwear metal inner lining processing difficulties, and effectively layer is thin, effective date is short and price is high, incompatibility part rod and tube partial-wear oil well demand can cause the serious oil pipe of rod and tube partial-wear to be ground leakage, causes down-hole accident, bring a lot of inconvenience to oil field production, and increased the cost of petroleum production.
The model utility content
The purpose of this utility model provides a kind of liner composite oil pipe with good wear-resisting, anticorrosion, wax control, good antiscale property performance, the technical problem of solution anticorrosion antiwear that can be permanently effective.
The technical solution adopted in the utility model is as follows:
A kind of wear-and corrosion-resistant liner composite oil pipe comprises outer tube, fixedly manage 2 in the setting-in one in described outer tube 1, and length of tube is greater than outer tube in described, and the both ends of the surface of interior pipe are given prominence to outside the outer tunnel end face.
Pipe 2 is for having thermoplasticity high-density polyethylene compound pipe or the superhigh molecular polyethylene compound pipe of wear-resisting, anticorrosion, wax control, good antiscale property performance in described.
Described outer tube 1 both ends of the surface be enclosed in described in the outer wall at pipe 2 two ends.
The utility model by in outer tube fixedly setting-in have the thermoplasticity high-density polyethylene compound pipe of wear-resisting, anticorrosion, wax control, good antiscale property performance or superhigh molecular polyethylene compound pipe as interior pipe, form an integrally-built oil pipe, make it under the prerequisite of not losing mechanical property, had good wear-resisting, anticorrosion, wax control, good antiscale property performance, improved the working life of oil pipe, save unnecessary workover eration, improved working efficiency, reduced cost of oil production.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of wear-and corrosion-resistant liner composite oil pipe comprises outer tube, fixedly manages 2 in the setting-in one in described outer tube 1, and interior pipe and outer tube are interference fit, and length of tube is greater than outer tube in described, and the both ends of the surface of interior pipe are given prominence to outside the outer tunnel end face.This moment, the both ends of the surface of oil pipe were the inner tube face, and the outer surface of oil pipe is outer tube outer surface.
Described outer tube is the single-layer metal oil pipe of prior art.Pipe 2 is for having thermoplasticity high-density polyethylene compound pipe or the superhigh molecular polyethylene compound pipe of wear-resisting, anticorrosion, wax control, good antiscale property performance in described.Described thermoplasticity high-density polyethylene compound pipe or superhigh molecular polyethylene compound pipe with wear-resisting, anticorrosion, wax control, good antiscale property performance is the prior art product.Described outer tube 1 both ends of the surface be enclosed in described in the outer wall at pipe 2 two ends, in making pipe be inlaid in cooperate among the outer tube more firm.Can adopt modes such as hot jacket, butt joint to install when mounted.
The utility model by in outer tube fixedly setting-in have the thermoplasticity high-density polyethylene compound pipe of wear-resisting, anticorrosion, wax control, good antiscale property performance or superhigh molecular polyethylene compound pipe as interior pipe, form one and have double-deck oil pipe, make it under the prerequisite of not losing mechanical property, had good wear-resisting, anticorrosion, wax control, good antiscale property performance, improved the working life of oil pipe, save unnecessary workover eration, improved working efficiency, reduced cost of oil production.
