Abstract
The utility model relates to the field of sucker rods and particularly relates to an anti-corrosion and wear-resistant sucker rod applicable to an oil well with strong corrosion and strong eccentric wear. According to the technical scheme, the anti-corrosion and wear-resistant sucker rod comprises a rod body and joints at two ends of the rod body. According to the improvement, an anti-corrosion and wear-resistant layer is coated outside the rod body. Two ends of the anti-corrosion and wear-resistant layer are turned towards the inner sides and are matched with outer convex edges along the two ends of the rod body. According to the anti-corrosion and wear-resistant sucker rod, due to the fact that the anti-corrosion and wear-resistant layer is coated outside the sucker rod body, the two ends of the anti-corrosion and wear-resistant layer are turned towards the inner sides and are matched with the outer convex edges of the joints at the two ends of the rod body, so that corrosive matters can be effectively prevented from entering the anti-corrosion and wear-resistant layer outside the rod body, and the outer surface of the rod body is free from being corroded. Meanwhile, the anti-corrosion and wear-resistant layer is made of materials with high strength, and the wear resistance of the sucker rod is improved. According to an oil field contrast test, the scheme demonstrates that the service life of the anti-corrosion and wear-resistant sucker rod is 8 times longer than the service life of an ordinary sucker rod.
Description
Technical field
The utility model relates to the sucker rod field, particularly a kind of sucker rod that is applicable to severe corrosive and the serious oil well of eccentric wear.
Background technology
Sucker rod is one of important tool of oil exploitation, increasing along with water injection well in oil fields, inclined shaft and horizontal well, traditional sucker rod is owing to lack the topping of necessity in the body of rod outside of metal material, the problem that in use mainly has two aspects: the one, because the existence of underground corrosion material (mainly being corrosive liquids and corrosive gas) very easily produces the corrosion to the sucker rod exposed part of metal material; The 2nd, sucker rod is constantly moving back and forth easy in the process and the borehole wall generation friction, particularly inclined shaft or horizontal well, and fricting movement is larger to the sucker rod infringement.This has just caused significantly shorten the application life of sucker rod, affects the normal production in oil field.
Summary of the invention
The purpose of this utility model is exactly for the anticorrosion of existing sucker rod and the problem of wear-resistant difference, and a kind of anticorrosive abrasion-proof sucker rod is provided.
Its technical scheme is: anticorrosive abrasion-proof sucker rod comprises the joint at the body of rod and body of rod two ends, and its improvements are in the body of rod outer wrap anticorrosion antiwear layer to be arranged.
Aforesaid anticorrosion antiwear layer inward at both ends side flanging cooperates with forming along the joint at body of rod two ends.
Outstanding effect of the present utility model is: since the oil pumping body of rod outer wrap the anticorrosion antiwear layer, the inward at both ends side flanging of anticorrosion antiwear layer forms with the body of rod two end joints and cooperates, when with other sucker rods or box cupling, socket on link closely after after the extruding, its opposite end section of closing anticorrosion antiwear layer flange with on the body of rod tightly contacts, prevent that effectively corrosive substance from entering in the outside anticorrosion antiwear layer of the body of rod, body of rod external surface is avoided corrosion.The anticorrosion antiwear layer is selected high-intensity material simultaneously, has improved the wear-resisting type of sucker rod.This programme proves by the Oil Field contrast test: be more than 8 times of common sucker rod life-span the application life of this anticorrosive abrasion-proof sucker rod.
Description of drawings
Accompanying drawing 1 is a kind of structure chart of typical Application Example; Accompanying drawing 2 is structure charts of a kind of anticorrosive abrasion-proof sucker rod.
The specific embodiment
Embodiment 1: as shown in Figure 2, anticorrosive abrasion-proof sucker rod 2 is comprised of the body of rod 5 and two ends male thread joint one, the body of rod 5 portion of external are by anticorrosion antiwear layer 4 whole parcel, and the inward at both ends side flanging of anticorrosion antiwear layer 4 partly overlaps with the outer lug of the body of rod 5 two ends male thread joints and cooperates.
Embodiment 2: as shown in Figure 1, are connected with socket with box cupling 1 respectively and are connected in anticorrosive abrasion-proof sucker rod 2 two ends.The socket 3 of anticorrosive abrasion-proof sucker rod 2 lower ends links to each other with oil pump plunger piston, is connected by box cupling between the every anticorrosive abrasion-proof sucker rod 2, and lower to the design well depth, the upper end links to each other with polished rod.
Embodiment 3: on the basis with reference to embodiment 1, change two ends male thread joint among the embodiment 1 into two ends box thread joint style, in this case, usually after mother's (interior) nipple position at two ends jumping-up is processed, behind the inward at both ends side flanging of anticorrosion antiwear layer, form overlap joint with the neighboring of female (interior) nipple and cooperate.
Embodiment 4: on the basis with reference to embodiment 1, change two ends male thread joint among the embodiment 1 into an end male thread joint and another box thread joint style, in this case, usually after female (interior) nipple position jumping-up is processed, behind the to the inside flange of anticorrosion antiwear layer, form overlap joint with the neighboring of female (interior) nipple and cooperate.
Anticorrosion antiwear layer material of the present utility model can be high-strength polyethylene or high-intensity resin material in addition, and the thickness of anticorrosion antiwear layer is selected at 1-20mm as required.Supporting box cupling and socket can be carried out preservative treatment, thus whole the raising sucker rod down-hole application life.
Claims (1)
1. anticorrosive abrasion-proof sucker rod comprises it is characterized in that the joint at the body of rod and body of rod two ends: in the body of rod outer wrap anticorrosion antiwear layer is arranged; Described anticorrosion antiwear layer inward at both ends side flanging cooperates with forming along the joint at body of rod two ends.
