Abstract
The utility model relates to a corrosion-resistant and wear-resistant composite oil pipe which is used in the fields of oil fields, chemical industry, waterline conveying, etc. The utility model can be widely used for a corrosion-resistant and wear-resistant injection-production pipe column of an oil water well and pipelines, such as an oil and gas gathering and transferring pipeline, a water injecting pipeline, a chemical industry pipeline, etc. The utility model is characterized in that a thermoplastic high-density polyethylene pipe is embedded in an oil pipe, both ends of the oil pipe adopt the convex structure of the thermoplastic high-density polyethylene pipe to form a structure, and the end part of the structure is the thermoplastic high-density polyethylene pipe. The utility model has the advantages that because the thermoplastic high-density polyethylene pipe is embedded in the oil pipe, the utility model has better paraffin-resistant, corrosion-resistant and wear-resistant performance, the service life of the oil pipe is extended, the cost of petroleum production extraction is reduced and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of anticorrosion antiwear composite oil pipe that use in fields such as oil field, chemical industry, conveying waterline that is used for, and can be widely used for the injection-production column jacket of oil/water well anticorrosion antiwear, and pipelines such as oil-gas gathering and transportation, water filling, chemical industry.
Background technique
The coating tubing of Oilfield using is to coat at the internal surface of oil pipe at present, makes oil pipe have wax control, corrosion-resistant performance.But because of its employed coating can peel off disengaging in the oil/water well using process, its coating fragment impurity often causes the generation of down-hole accident, causes workover eration.And existing coating tubing do not possess wear-resisting property, and incompatibility part rod and tube partial-wear oil well demand can cause the serious oil pipe mill of rod and tube partial-wear to leak, and causes down-hole accident, produces to the oil field and brings a lot of inconvenience, and increased the cost of petroleum production.
Summary of the invention
The purpose of this utility model provides a kind of anticorrosion antiwear composite oil pipe with wax control preferably, anticorrosion, wear-resisting property.
The anticorrosion antiwear composite oil pipe is characterized in that: be embedded with at oil pipe have wax control, the interior pipe of anticorrosion, wear-resisting property, the structure that pipe protrudes in adopt at the two ends of oil pipe, forming the end is the end face of interior pipe protrusion.
Describedly have wax control, interior pipe anticorrosion, wear-resisting property is the thermoplasticity high density polyethylene pipe.
The utility model has the advantages that: since be embedded with at oil pipe have wax control, the thermoplasticity high density polyethylene pipe of anticorrosion, wear-resisting property, so have wax control, anticorrosion, wear-resisting property preferably, improve the working life of oil pipe, reduced cost of oil production, improved working efficiency.
Description of drawings
Fig. 1 is the structural representation of anticorrosion antiwear composite oil pipe.
Embodiment
See Fig. 1, the anticorrosion antiwear composite oil pipe is embedded with thermoplasticity high density polyethylene pipe 2 at oil pipe 1, and in the structure that the two ends of oil pipe adopt the thermoplasticity high density polyethylene pipe to protrude, forming the end is the end face of thermoplasticity high density polyethylene pipe.
Claims (2)
1, anticorrosion antiwear composite oil pipe is characterized in that: be embedded with at oil pipe have wax control, the interior pipe of anticorrosion, wear-resisting property, the structure that pipe protrudes in adopt at the two ends of oil pipe, forming the end is the end face of interior pipe protrusion.
2, anticorrosion antiwear composite oil pipe according to claim 1 is characterized in that: describedly have wax control, interior pipe anticorrosion, wear-resisting property is the thermoplasticity high density polyethylene pipe.
