Abstract
The utility model relates to an anti-friction sucker rod coupling with bidirectional protection for the pumping well, in particular the inclined well in the oil recovery process. The utility model comprises a body 1 and a nano material protective layer 2 arranged on the outer surface of the body 1. In the pumping well, in particular the production process of the inclined well, the sucker rod coupling can perform the bidirectional protective functions of protecting the sucker rod from breaking and tripping and protecting an oil pipe from wearing out and leakage. Utilizing the sucker rod coupling, the production ageing effect of the oil well can be improved, the workover treatment can be reduced, and the production cost of the oil well can be reduced. The sucker rod coupling is used widely.
Description
Technical field:
The utility model relates to a kind of particularly down-hole rod string parts of inclined shaft oil recovery process of pumpingh well that are used for, and belongs to mechanical oil recovery instrument class.
Background technology:
In the pumpingh well manufacturing process, rod string moves up and down in oil pipe repeatedly, all is in Frotteurism between the two all the time, and then friction is particularly serious in inclined shaft.At present, because normally used rod collar wear resistance is relatively poor and do not have the resistive energy of antifriction, thereby rod parting, oil pipe leakage accident such as scrap happens occasionally, and the oil well ordinary production is caused adverse effect, and repair operation on needing, make the oil well production cost up.
Summary of the invention:
The purpose of this utility model is to provide a kind of particularly can effectively protect R a T in the inclined shaft manufacturing process at pumpingh well, prevent the bidirectional protective antifriction rod collar that rod parting and oil pipe are missed.
The utility model is to realize like this.This kind rod collar is made up of body and nano material topping, and this external surface is provided with the nano material topping.Because the nano material topping has certain degree of hardness, make itself to have the antifriction corrosion resisting property, thereby reach the purpose of protecting sucker rod.Simultaneously; this topping has the resistive energy of good antifriction; tube inner wall is played the lubricated effect of falling frictional resistance, preventing tube inner wall abrasion leakage; thereby this kind rod collar both had the bidirectional protective function to R a T; the resistance of can reducing friction simultaneously has the load of reduction and effect of saving energy.
The utility model particularly can play protection in the inclined shaft manufacturing process at pumpingh well and take out bar and prevent from disconnectedly to take off and protect oil pipe to prevent the bidirectional protective effect that abrasion is missed; utilize it can improve the oil well production timeliness; reduce workover treatment, reduce the oil well production cost, be suitable for extensive employing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Fig. 2 is its lateral view.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of body 1 and nano material topping 2, and its structure, assembled relation are as follows: body 1 external surface is provided with nano material topping 2.Wherein, body 1 and the conventional rod collar structure of same size, measure-alike.Nano material topping 2 thickness 1～2mm; thereby make the total body diameter of this kind box cupling be slightly larger than conventional rod collar external diameter; this topping adopts metal nano material or nonmetal nano material to be worked on box cupling body 1 external surface through special process, selects for use according to different blocks down-hole, oil field medium chemical property.
Claims (1)
1, a kind of bidirectional protective antifriction rod collar is made up of body (1) and nano material topping (2), it is characterized in that: body (1) external surface is provided with nano material topping (2), and the total body diameter of box cupling is slightly larger than conventional rod collar.
