Abstract
A kind of hot melt parcel anticorrosive abrasion-proof sucker rod.The anticorrosion antiwear layer existed to overcome existing coated anticorrosive abrasion-proof sucker rod easily comes off problem, anticorrosion antiwear effect does not reach the deficiency of oil producing operation requirement, the utility model comprises sucker rod, wearing layer, the rod end at the body of rod two ends of sucker rod is installed with box cupling, the body of rod and rod end external surface are coated with anticorrosion antiwear layer, and anticorrosion antiwear layer is that reinforced nylon is material modified; The anticorrosion antiwear layer of rod end end is to the inside port blockage of rod end.Its beneficial effect is rational in infrastructure, the body of rod and the coated anticorrosion antiwear layer difficult drop-off of rod end thereof, the anticorrosion antiwear performance of the sucker rod of raising and application life thereof.
Description
Technical field
The utility model relates to the sucker rod that a kind of oil and gas development uses, and especially relates to a kind of hot melt parcel anticorrosive abrasion-proof sucker rod being applicable to corrosion and eccentric wear Severe well.
Background technology
Along with water injection well in oil fields, inclined shaft, horizontal well increasing, because traditional sucker rod lacks necessary topping in metal material body of rod outside, in use mainly deposit problem both ways: one is the existence due to underground corrosion material (mainly corrosive liquids and corrosive gas), very easily corrosion is produced to the sucker rod exposed part of metal material; Two is sucker rods easily produces with oil pipe and rubs in constantly reciprocating movement, makes sucker rod partial wear seriously, in the oil producing operation of particularly inclined shaft or horizontal well.Corrosion and eccentric wear cause significantly shorten the application life of sucker rod, affect the normal production in oil field.
In order to solve sucker rod corrosion and eccentric wear problem, there is a lot of patented technology, as coated anticorrosive abrasion-proof sucker rod, have anticorrosion antiwear layer in the body of rod outer wrap of sucker rod, but there is anticorrosion antiwear layer and easily to come off problem in it, anticorrosion antiwear effect does not reach the deficiency of oil producing operation requirement.
Utility model content
The anticorrosion antiwear layer existed to overcome existing coated anticorrosive abrasion-proof sucker rod easily comes off problem, and anticorrosion antiwear effect does not reach the deficiency of oil producing operation requirement, and the utility model provides a kind of hot melt to wrap up anticorrosive abrasion-proof sucker rod.
The utility model solves the technical scheme that its technical problem adopts: hot melt parcel anticorrosive abrasion-proof sucker rod comprises sucker rod, wearing layer, the rod end at sucker rod body of rod two ends is installed with box cupling, the body of rod and rod end external surface are coated with anticorrosion antiwear layer, and anticorrosion antiwear layer is that reinforced nylon is material modified; The anticorrosion antiwear layer of rod end end is coated to the inside port blockage of rod end.
The beneficial effects of the utility model are, rational in infrastructure, and the body of rod and the coated anticorrosion antiwear layer difficult drop-off of rod end thereof, improve anticorrosion antiwear performance and the application life thereof of sucker rod.
Accompanying drawing explanation
Fig. 1 is the utility model hot melt parcel anticorrosive abrasion-proof sucker rod structural representation.
In figure: 1. box cupling, 2. rod end, 3. anticorrosion antiwear layer, the 4. body of rod.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.But those skilled in the art should know, the invention is not restricted to listed detailed description of the invention, as long as spirit according to the invention, all should be included in protection scope of the present invention.
The rod end 2 at the body of rod 4 two ends of the utility model hot melt parcel anticorrosive abrasion-proof sucker rod is installed with box cupling 1, the body of rod 4 and rod end 2 external surface are coated with anticorrosion antiwear layer 3, anticorrosion antiwear layer 3 is that reinforced nylon is material modified, reinforced nylon 6 is material modified specifically, and this is material modified has good Corrosion Protection and abrasion resistance.The anticorrosion antiwear layer 3 of rod end 2 end is coated to the inside port blockage of rod end, is formed coordinate with the joint along body of rod two ends, effectively can stop contacting of sucker rod and corrosive medium, slow down the wearing and tearing of R a T, effectively prevent fouling and slow down wax deposition.Box cupling 1 adopts surfacing bidirectional protective, plating tungsten anticorrosion antiwear technology, can effectively coordinate sucker rod to have overall anticorrosion antiwear effect.
Outstanding effect of the present utility model is: due at the outside coated anticorrosion antiwear layer of sucker rod, anticorrosion antiwear layer inward at both ends side flanging is formed with the body of rod two end joint and coordinates, when with other sucker rods or box cupling, socket on link closely and extrude after, tightly contact with two ends anticorrosion antiwear layer flange, effectively prevent corrosive substance from entering in the outside anticorrosion antiwear layer of the body of rod, body of rod external surface is from corrosion.Anticorrosion antiwear layer adopts reinforced nylon 6 material modified simultaneously, and improve the abrasion resistance of sucker rod, laboratory and field trial prove, the application life of the utility model sucker rod is more than 4 times of the common sucker rod life-span.
The utility model can also by the body of rod 4, rod end 2 coated anticorrosion antiwear layer respectively, and the wearing layer of rod end 2 end is coated to sucker rod endoporus one side flanging, overlaps coordinate with sucker rod 2 two ends male thread blank area.The monolateral thickness of anticorrosion antiwear layer 3 can reach 2.3mm, be applicable to φ 16, φ 19, φ 22, φ 25, φ 28 specification sucker rod product, box cupling 1 adopts surfacing process or plating tungsten process, improves abrasion resistance and the anti-corrosive properties of box cupling, thus overallly can improve sucker rod application life.
It should be noted that above-described embodiment is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiment and not depart from the right of this patent.
Claims (1)
1. a hot melt parcel anticorrosive abrasion-proof sucker rod, comprise sucker rod, wearing layer, the rod end at the body of rod two ends of sucker rod is installed with box cupling, it is characterized in that: the described body of rod (4) and rod end (2) external surface are coated with anticorrosion antiwear layer (3), anticorrosion antiwear layer (3) for reinforced nylon material modified; The anticorrosion antiwear layer (3) of rod end (2) end is coated to the inside port blockage of rod end (2).
