Abstract
The utility model relates to a seamless anticorrosion wear-resistant composite oil pipe connecting structure which is used at a position where two composite oil pipes are connected. A composite gasket is additionally arranged at the position where the composite oil pipes are connected, and pore diameter of the composite gasket is identical with inner diameter of a composite lining pipe. At the position where the composite oil pipes are connected, the composite oil pipes on two sides are screwed together by an oil pipe coupling, so that the composite gasket is enabled to be compressed and sealed between ports of the composite oil pipes on the two sides. By additionally arranging the gasket, no seam exists on the inner wall of the oil pipe lining pipe of an oil well, so that corrosion is reduced, service lives of the oil pipes are prolonged, fault rate of the oil well is reduced, oil exploitation cost is lowered, and working efficiency is improved.
Description
Technical field
The utility model relates to the draw bail between composite oil pipe, is specifically related to a kind of anti-eccentric wear of oil field, producing well, water injection well, directed producing well, horizontal producing well, rod and tube partial-wear producing well, draw bail between etch-proof composite oil pipe of being applicable to.
Background technology
At present, the composite oil pipe that oil well, water injection well, directed producing well, horizontal producing well, rod and tube partial-wear producing well are used, is the mode of etch-proof composite material as liner pipe that adds at tube inner wall.But, owing to there being the gap of 8-10mm two tubing coupling connection places, can cause concentrating of hot spot, addition polymerization corrosion, makes oil pipe not reach complete etch-proof object.The fault of oil well is increased.
Summary of the invention
The purpose of this utility model is to provide a kind of seamless antiseptic abrasion-proof compound oil pipe draw bail, the problem being easily corroded to eliminate composite oil pipe connection place.
The purpose of this utility model is achieved through the following technical solutions.
A seamless antiseptic abrasion-proof compound oil pipe draw bail, for the connecting portion of two composite oil pipes, described composite oil pipe is comprised of the composite material as liner pipe of outer field steel oil pipe and inner ring; At the connecting portion of two composite oil pipes, add a composite material pad, its aperture is identical with the internal diameter of composite material as liner pipe; At composite oil pipe interface, tubing coupling spins together both sides composite oil pipe, and composite material pad is compressed between the port of the composite oil pipe that is enclosed in both sides.
The external diameter of composite material pad is greater than the external diameter of steel oil pipe port, at the inner ring of tubing coupling, is provided with a concave ring groove, and composite material pad clamping or molten note are located in concave ring groove.
The utility model is owing to having added the pad identical with internal lining pipe diameter of bore in tubing coupling inwall centre position, make the oil tube inner lining inside pipe wall of oil well there is no gap, make full producing well, water flooding well pipe column wall is seamless, reduced corrosion, improve the application life of oil pipe, reduced the fault rate of oil well, improved being excused from a college course the phase of workover treatment of producing well, water injection well, directional well, horizontal well, rod and tube partial-wear well, the cost of winning that has reduced oil, has improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the draw bail schematic diagram of the seamless antiseptic abrasion-proof compound oil pipe of the utility model.
In figure:
1, composite material as liner pipe; 2, steel oil pipe; 3, tubing coupling; 4, composite material pad; 5, concave ring groove.
The specific embodiment
Referring to Fig. 1, antiseptic abrasion-proof compound oil pipe draw bail that the utility model is seamless, for the connecting portion of two composite oil pipes.Described composite oil pipe is comprised of the composite material as liner pipe 1 of outer field steel oil pipe 2 and inner ring.At the connecting portion of two composite oil pipes, add a composite material pad 4, its aperture is identical with the internal diameter of composite material as liner pipe 1.At composite oil pipe interface, tubing coupling 3 spins together both sides composite oil pipe, and composite material pad 4 is compressed between the port of the composite oil pipe that is enclosed in both sides.Described composite material can be selected ultra-high molecular weight polyethylene or the identical chemical materials of speciality.
As preferred version, the external diameter of composite material pad 4 is greater than the external diameter of steel oil pipe 2 ports, inner ring in tubing coupling 3 is provided with a concave ring groove 5, composite material pad 4 clampings or molten note location in concave ring groove 5, so not only can make composite material pad 4 exactly between composite oil pipe two-port, pad is not come off.And can make composite material pad 4 that the port of steel oil pipe 2 is all sealed and covered tightly.
When two oil pipes connect in use, they are tightened in to reach together with tubing coupling 3 and set requirement.
