The utility model has the advantages of this sucker rod has increased special adhesion layer on traditional sucker rod basis, this adhesion layer can reduce inside ground of tub pole frictional force effectively, improves the greasy property greatly, has improved the non -corrosibility and the wearability of sucker rod, has overcome ceramic coating and because of the time produces the drawback of damaging for a long time, has effectively prolonged the life of sucker rod.
Description
Technical field
This utility model relates to a kind of oil exploration equipment accessory, particularly relates to a kind of abrasion-proof sucker rod.
Background technology
Sucker rod is the slender rod piece of rod-pumped well, and it connects polished rod, under connect oil pump, play transmission power effect.The material of sucker rod is generally high-carbon steel plating hard chromium on surface, couples together with one one, female thread hoop, extend on the piston at oilbearing stratum in oil pipe, carrys out pump oil by reciprocating motion.
Sucker rod is the critical component of oil extraction, and along with oil field enters high water-cut stage, the lubricating coefficient of tube rod contact surface is greatly lowered, and changes force-bearing situation and the deformation extent of sucker rod, makes side-abrasion of rod string corrosion damage increasingly severe.
Traditional sucker rod majority uses single ceramic coating, ceramic coating is along with the prolongation of the time of use, breakage easily occurs, the greasy property of tube rod can be made significantly to reduce after breakage occurs, thus cause tube rod by force unbalance, tube rod directly contacts with crude oil simultaneously, causes tube rod abrasion and corrosion, reduces service life.
Utility model content
This utility model solves the technical problem that and is, in prior art, the coefficient of friction of common sucker rod contact surface in tube rod when oil field high water-cut stage uses increases, change the force-bearing situation of sucker rod, increase the deformation degree of sucker rod, eccentric wear corrodes to make sucker rod occur, causes shorten the service life of sucker rod.
For solving the problems referred to above, we have proposed a kind of abrasion-proof sucker rod, this sucker rod adds special adhesion layer on the basis of tradition sucker rod, this adhesion layer can be effectively reduced tube rod internally frictional force, it is greatly improved greasy property, improve anti-corrosive properties and the wearability of sucker rod, overcome ceramic coating because of the drawback producing and damaging of long duration, the effectively service life of prolongation sucker rod.
For realizing the demand, this utility model is achieved through the following technical solutions above-mentioned purpose: a kind of abrasion-proof sucker rod, including the body of rod, joint and box cupling, described body of rod two ends are provided with joint, joint is provided with box cupling, the described body of rod, joint, the surface spraying of box cupling have ceramic coating, the surface attachment adhesion layer of described ceramic coating；
Described adhesion layer is 65 ° of bulk materials of hardness HRC ＞.
Further, a kind of abrasion-proof sucker rod, the thickness >=2mm of described adhesion layer.
Further, a kind of abrasion-proof sucker rod, the particle size range of the bulk material of described adhesion layer is 20-40 mesh.
Further, a kind of abrasion-proof sucker rod, described box cupling includes hoop body, female thread and coating, described hoop body generally cylindrical shape, is provided with reinforcement in described hoop body, and described reinforcement is tinsel, is parallel to hoop body bus and arranges.
Further, a kind of abrasion-proof sucker rod, described bulk material is non-metallic particle.
Further, a kind of abrasion-proof sucker rod, described bulk material be kernel be metal, be coated with the hybrid particles of nonmetallic coating.
Further, a kind of abrasion-proof sucker rod, described bulk material is ceramic particle.
This utility model is in use, by piece one is sequentially connected with of sucker rod, upper end is connected with polished rod, lower end is connected with pump, even if use in the oil field of high water-cut stage, as when its adhesion layer being provided with bulk material makes crude oil flow in tube rod will not increasing friction force, simultaneously, hoop body is internally provided with metal reinforcing, prevents the power swinging at sucker rod or producing during twisting from making to rupture at pipe collar.Add whole sucker rod system stability in use.
The beneficial effects of the utility model are: this sucker rod adds special adhesion layer on the basis of tradition sucker rod, this adhesion layer can be effectively reduced tube rod internally frictional force, it is greatly improved greasy property, improve anti-corrosive properties and the wearability of sucker rod, overcome ceramic coating because of the drawback producing and damaging of long duration, the effectively service life of prolongation sucker rod.
