Abstract
The utility model relates to a super high molecular weight inside lining antiseptic and durable compound pipe which is used for the fields of oil well, chemical industry, delivering water line. The main body is an oil pipe; the oil pipe is embedded with high molecular polyethylene inner pipe; the inner pipe has a shape memory function, interference adhesive cooperation with the oil pipe, which is embedded in the oil pipe. The utility model can be extensively used for the pouring and exploiting pipe pillar of the oil and water well, scouring well and the delivery of gas oil, chemical pipeline, heat supplying pipeline and so on. Because of the embedment of the super high molecular weight inner pipe, the super high molecular weight inner pipe is tightly adhered to the oil pipe, enhancing the antiseptic capacity and enhancing the service life of the oil pipe and reducing the oil exploiting cost.
Description
Technical field
The utility model relates to a kind of polyethylene liner interference assembling anticorrosion antiwear composite oil pipe that is used for fields such as oil field, chemical industry, conveying waterline, belongs to the injection-production column jacket of oil recovery well, water injection well, and oil gas is carried, the application apparatus in the chemical pipeline.
Background technique
At present, the coating tubing of Oilfield using is to establish coating layer on internal surface, makes oil pipe have performance anticorrosion, wax control.But because of employed coating layer can peel off disengaging in the oil/water well using process, coating fragment impurity often causes the generation of down-hole accident, causes causing workover eration.And existing coating tubing does not possess wear-resisting property, and the demand of incompatibility part rod and tube partial-wear oil well causes that the serious oil pipe mill of rod and tube partial-wear leaks, and causes down-hole accident.The problems referred to above bring a lot of inconvenience for the production in oil field, and have increased the cost of petroleum production.
Summary of the invention
The purpose of this utility model is to overcome the deficiency in the existing technology, provides a kind of ultra-high molecular weight polyethylene inside lining anti-corrosive wear-resisting composite oil pipe.
The technical solution of the utility model is as follows.
The wear-resisting composite oil pipe of super high molecular weight inside lining anti-corrosive, its main body are oil pipe, are embedded with in the ultra-high molecular weight polyethylene at described oil pipe and manage.
Pipe is the employing shape memory plastic, cooperates with the oil pipe interference is gluing in the described ultra-high molecular weight polyethylene, embeds in the oil pipe.
The plastic tube that the utility model adopts, utilize the memory characteristic of shape memory plastic, cooperate with the oil pipe interference is gluing, pipe in the PE is embedded in the oil pipe, memory characteristic bounce-back by plastics dilates gluing, the interior pipe of oil pipe and ultra-high molecular weight polyethylene is combined closely become one, do not separate, do not come off.Have anticorrosion preferably, wear-resisting, anti-wax deposition performance, reduced cost of oil production the working life of having improved oil pipe, improved working efficiency.
Description of drawings
Accompanying drawing is the sectional structure schematic representation of the utility model anticorrosion antiwear composite oil pipe.
Among the figure: 1, oil pipe, 2, pipe in the ultra-high molecular weight polyethylene.
Embodiment
Referring to accompanying drawing, pipe in the ultra-high molecular weight polyethylene, comprise pipe 2 in oil pipe 1 and the ultra-high molecular weight polyethylene, be embedded with at oil pipe 1 and manage 2 in the ultra-high molecular weight polyethylene that pipe 2 has shape memory function, embeds oil pipe 1 with the gluing assembly structure of oil pipe 1 interference in the ultra-high molecular weight polyethylene.Therefore ultra-high molecular weight polyethylene internal lining pipe 2 is combined closely with oil pipe 1, becomes one, and has improved antiseptic power.Because the PE material has self-lubricating property, has reduced the friction of beam hanger and oil pipe, has improved the working life of oil pipe.Reduce cost of oil production, improved working efficiency.
Claims (2)
1, the wear-resisting composite oil pipe of a kind of super high molecular weight inside lining anti-corrosive, its main body is oil pipe (1), it is characterized in that: be embedded with pipe (2) in the ultra-high molecular weight polyethylene at described oil pipe (1).
2, the wear-resisting composite oil pipe of super high molecular weight inside lining anti-corrosive according to claim 1 is characterized in that: in the described ultra-high molecular weight polyethylene pipe (2) be adopt shape memory plastic, with oil pipe (1) the gluing cooperation of interference, in the embedding oil pipe (1).
