Abstract
The utility model discloses an anti-corrosion, anti-scale and wear resistant sucker rod in the technical field of oil field machinery to solve the problems that the sucker rod in the prior art is short in service life and low in work efficiency caused by that the sucker rod is easily corroded and abraded. The anti-corrosion, anti-scale and wear resistant sucker rod comprises a sucker rod body which is arranged in a sucker rod tubular column. Two ends of the sucker rod body are in an arc shape. The two ends of the sucker rod body are respectively provided with a spanner square diameter. The spanner square diameter is connected with an outer threaded connector through a pushing and bearing surface shoulder. The outer surface of the sucker rod body is provided with a nonmetal anti-corrosion layer. Due to the adoption of the technical scheme, the anti-corrosion, anti-scale and wear resistant sucker rod has the advantage of being simple in structure. Due to the fact that nonmetal anti-scale and anti-corrosion materials are arranged on the sucker rod body, the anti-corrosion, anti-scale and wear resistant sucker rod is capable of effectively preventing the sucker rod from scaling and being corroded, prolonging service life, and is especially suitable for an oil well which severely scales and is severely corroded.
Description
Technical field
The utility model relates to a kind of pumping unit in the oilfield machinery technical field, particularly a kind of anti-corrosion anti-scale abrasion-proof sucker rod.
Background technology
Oil pumper is as present oil extraction in oil field capital equipment, and sucker rod is the critical component of oil pumping system, is used for connecting oil well pump and oil pumper, plays the effect of transferring power, the good and bad stable operation that directly determines whole oil pumping system of the performance of sucker rod.
A kind of sucker rod is arranged in prior art, comprise the sucker rod body of being located in the oil pick-up tube tubing string, the two ends of described sucker rod body are curved, the two ends of sucker rod body are respectively equipped with spanner Fang Jing, described spanner Fang Jing is connected with male connection by pushing away the bearing surface shoulder, and the material of sucker rod body is generally selected carbon steel.
Its weak point is, sucker rod is immersed in the whole oil pipe column of oil extraction system in the course of the work for a long time, contain hydrogen sulfide, carbon dioxide, water, mould and other comprehensive corrosion factors and hard suspended particulate in the liquid of pumping, therefore, corrosion and the wear problem of sucker rod body become increasingly conspicuous, corrosion and wearing and tearing make the life-span decrease of sucker rod, replacement cycle significantly shortens, cause many oil wells because of sucker rod corrosion and the frequent operation of wear out failure, cost increases, and affects simultaneously field output.Corrosion-resistant and wear failure problem for sucker rod, domestic commonly used anticorrosion and improve wear-resisting method mainly contain high-frequency heating to sucker rod carry out hard surfacing, to the sucker rod surface electroplating or chemical plating, pit shaft adds corrosion inhibiter etc., but corrosion mitigating effect is unsatisfactory.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of simple in structure, easy to make, has the sucker rod of anticorrosion, antiscale, anti-wear performance.
The purpose of this utility model is achieved in that a kind of anti-corrosion anti-scale abrasion-proof sucker rod, comprise the sucker rod body of being located in the oil pick-up tube tubing string, the two ends of described sucker rod body are curved, the two ends of sucker rod body are respectively equipped with spanner Fang Jing, described spanner Fang Jing is connected with male connection by pushing away the bearing surface shoulder, and the external surface of described sucker rod body is provided with nonmetal anticorrosive coat.
The utility model when work, at first the male connection at sucker rod two ends is inserted in the box cupling of corresponding parts to be connected, can come into operation after tightening by spanner Fang Jing.Owing to having adopted above technical scheme, the beneficial effects of the utility model are: simple in structure, owing to having adopted nonmetal anti-scaling anti-corrosive material on the sucker rod body, therefore can effectively reduce the sucker rod fouling corrosion, can extend the sucker rod life-span, be specially adapted to the serious oil well of fouling corrosion.
As further improvement of the utility model, the thickness of described anticorrosive coat is 1 ~ 5mm, further strengthens the anticorrosion antiwear performance of sucker rod body.
As further improvement of the utility model, the two ends of described sucker rod body are respectively installed with wiper block, the setting that matches with the internal diameter of oil pick-up tube tubing string of the external diameter of described wiper block, in when, in use procedure, eccentric wear occuring when, at first wiper block contacts with the oil pick-up tube inner tubal wall, thereby effectively avoid rod collar abrasion worn out, significant prolongation sucker rod application life and oil well pump detection period, improved enterprise work efficient.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 male connection; 2 push away the bearing surface shoulder; 3 spanner Fang Jing; 4 wiper blocks; 5 anticorrosive coats; 6 sucker rod bodies.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
as shown in Figure 1, a kind of anti-corrosion anti-scale abrasion-proof sucker rod, comprise the sucker rod body 6 of being located in the oil pick-up tube tubing string, the two ends of sucker rod body 6 are curved, the two ends of sucker rod body 6 are respectively equipped with footpath, spanner side 3, footpath, spanner side 3 is connected with male connection 1 by pushing away bearing surface shoulder 2, the external surface of sucker rod body 6 is provided with anticorrosive coat 5, anticorrosive coat 5 is selected nonmetals, in order to guarantee good antiscale property Corrosion Protection preferably, the preferred light and corrosion-resistant material of anticorrosive coat 5, guarantee the sucker rod external surface smooth enough of moulding on spraying coating process, can avoid brilliant and dirty the adhering to of wax, thereby reach the etch-proof purpose of good antiscale property.For further strengthening the anticorrosion antiwear performance of sucker rod body 6, the thickness of anticorrosive coat 5 is preferably 1 ~ 5mm.The two ends of sucker rod body 6 also are respectively installed with wiper block 4, the setting that matches with the internal diameter of oil pick-up tube tubing string of the external diameter of wiper block 4, the preferred friction factor of wiper block 4 is little, the superb macromolecular material of anti-wear performance, this material and steel are mutually during mutual friction, its friction factor is only 1/2 of nylon, under similarity condition the mortar abrasion index of this material be nylon 1/4, be carbon steel 1/7, be 1/27 of brass.On manufacture craft, the wiper block 4 that adopts sintering process that the supra polymer material is made is cemented on sucker rod.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
