Abstract
The utility model provides an anticorrosion and antiabrasion pair of a sucker rod and belongs to a device used for oilfield production. The anticorrosion and antiabrasion pair comprises a rod body, wherein the surface of the rod body is coated by a nylon layer; the upper part and the lower part of the rod body are respectively fixed with a first anticorrosion and antiabrasion support sleeve and a second anticorrosion and antiabrasion support sleeve; connectors are respectively formed on the two ends of the rod body; and an opening and closing connecting barrel is arranged on one of the connectors. The anticorrosion and antiabrasion pair of the sucker rod can be used in a pump well with a rod in an oil field, and can replace the current sucker rod without any anticorrosion and antiabrasion measure. The nylon layer coats on the surface of the rod body, the anticorrosion and antiabrasion support sleeves and the opening and closing connecting barrel adopt high-quality anticorrosion and antiabrasion steel, the contact between the rod body and oil well liquid with corrosivity is isolated, the anticorrosion and antiabrasion properties are strong, the effect of prolonging the service life of the sucker rod is realized, and economic loss brought by the damage of the sucker rod is reduced.
Description
Technical field
The utility model provides a kind of field produces device, especially a kind of oil recovery production sucker rod device.
Background technology
In oilfield process, sucker rod pumping is topmost oil production method.During sucker rod pumping, the down-hole part is made up of deep well pump, oil pipe, sucker rod three parts.Sucker rod wherein plays power is passed to underground effect from ground.Because of the technological deficiency of sucker rod pumping system, sucker rod can produce eccentric wear with oil pipe in the process of upper and lower reciprocating motion transferring power.Along with deepening continuously of oil field development, the moisture content in the oil well produced liquid constantly rises, and the lubricating condition between sucker rod and oil pipe can variation.Simultaneously, well liquid has corrosiveness.Under the acting in conjunction of attrition and attack, sucker rod can very fast damage, becomes and can not satisfy instructions for use.Change sucker rod and not only can cause oil well to stop production, also can bring economic loss, increase cost of production.But up to the present, also there is not effectively to solve the method for pumping rod anti-corrosive abrasionproof problem.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pumping rod anti-corrosive abrasionproof pair, to improve its corrosion and wear performance.
The utility model is to realize like this, pumping rod anti-corrosive abrasionproof pair, it has the bar body, the surface of bar body is coated with nylon layer, the first corrosion and wear support set and the second corrosion and wear support set are fixedly arranged respectively at bar upper part of body, bottom, the two ends of bar body have joint respectively, on the joint therein the folding connecting cylinder are installed.
Adopt the pumping rod anti-corrosive abrasionproof pair of said structure, can use at the oil field rod pumped well, substitute the sucker rod of existing no any corrosion and wear measure.Bar body surface covered with nylon layer, corrosion and wear support set, folding connecting cylinder can adopt high-quality anticorrosion antiwear steel, completely cut off contacting of bar body and mordant well liquid, the wear-and corrosion-resistant performance is strong, play the effect in prolongation sucker rod application life, reduced the economic loss of bringing because of the sucker rod damage.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the horizontal section enlarged drawing of the bar body in the utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
As shown in drawings, the pumping rod anti-corrosive abrasionproof pair of the utility model, it has bar body 2, the surface of bar body is coated with nylon layer 3, the first corrosion and wear support set 1 and the second corrosion and wear support set 4 are fixedly arranged respectively at bar upper part of body, bottom, the two ends of bar body have joint 6 respectively, on the joint therein folding connecting cylinder 5 are installed.
The material of the nylon layer of the complete coating of bar body surface is modification of nylon high temperature resistant, anticorrosion antiwear.Nylon layer can adopt the extrusion molding mode to make.Abrasionproof support set, folding connecting cylinder can adopt high-quality anticorrosion antiwear steel material.Joint is installed together by screw thread and folding connecting cylinder.There is internal thread at folding connecting cylinder two ends.
When oil well uses, use special-purpose elevator to be stuck in the recessed position of a corrosion and wear support set external surface.Rise to suitable height with lifting means barre body, by the screw thread on the joint of folding connecting cylinder and bar body, next root pumping rod anti-corrosive abrasionproof pair is linked together with a last pumping rod anti-corrosive abrasionproof pair, successively G.I.H.When installation, dismounting, pipe wrench should be stuck in the recessed position of corrosion and wear support set external surface.
