Abstract
The utility model provides a dedicated ultra-high strength plug-in type pumping rod for screw pumps, and belongs to the field of petroleum mechanical recovery devices. The pumping rod comprises a rod body, a threaded hoop sleeve, a nut in the threaded hoop sleeve and a spare nut in the threaded hoop sleeve, wherein, a concave groove, external threads and wrench squares are formed at the upper end of the rod body; external threads and a convex connector are arranged at the lower end of the rod body; and the threaded hoop sleeve, the nut in the threaded hoop sleeve and the spare nut in the threaded hoop sleeve are mounted at the lower end of the rod body. Such is the structure of the dedicated single ultra-high strength plug-in type pumping rod for the screw pumps. A plurality of dedicated single ultra-high strength plug-in type pumping rods for the screw pumps can be connected with each other in sequence as required, so as to form a pumping rod pillar. The utility model not only has ultra-high anti-drop performance and torsional strength, but also has the characteristics of simple assembly and convenient installation.
Description
Affiliated technical field
The special-purpose sucker rod of a kind of superhigh strength plug-in type screw pump belongs to petroleum machinery oil production equipment field.
Background technique
General common sucker rod and the fan-shaped bar head sucker rod of adopting of the sucker rod that is applied to the drive screw pump sump at present.Common sucker rod generally is applied to the pumping production well and moves reciprocatingly because of it connects for straight thread, is applied to screw bolt well and recovers the oil, and its anti-twisting property is not enough.Fan-shaped bar head sucker rod all can cause with the connection part of this rod collar looseningly in screw bolt well body of rod rotary work, causes the dropout accident, so that influence the normal oil producing operation of screw pump.
Summary of the invention
Be applied to the deficiency that drive screw pump sump sucker rod anti-twisting property is not enough and connection part is easily loosening at present in order to overcome, the utility model provides a kind of superhigh strength plug-in type screw pump special-purpose sucker rod, the special-purpose sucker rod of this superhigh strength plug-in type screw pump not only has superhigh strength anti-avulsion, torsional property, and has assembling characteristics simple, easy for installation.
The technological scheme that its technical problem that solves the utility model adopts is: the special-purpose sucker rod of a kind of superhigh strength plug-in type screw pump is female by being equipped with in the sucker rod body of rod, screw thread hoop cover inner nut, the screw thread hoop cover, screw thread hoop cover is formed.Sucker rod body of rod upper end has Baltimore groove, outside thread and spanner side, the lower end has outside thread and convex joint, earlier screw thread hoop cover is sleeved on sucker rod body of rod lower end, it is interior female fully to refill screw thread hoop cover inner nut and screw thread hoop cover, promptly constitutes the special-purpose sucker rod of single superhigh strength plug-in type screw pump.During following well operations, the convex joint of the sucker rod body of rod lower end of single superhigh strength plug-in type screw pump special use sucker rod is pegged graft with the Baltimore groove of the sucker rod body of rod upper end of the following special-purpose sucker rod of another root superhigh strength plug-in type screw pump and is cooperated, then screw thread hoop cover is connected with the outside thread of the sucker rod body of rod upper end of the special-purpose sucker rod of another root superhigh strength plug-in type screw pump and tightens, in screw thread hoop cover, the many special-purpose sucker rods of single superhigh strength plug-in type screw pump can be in turn connected into rod string to the Baltimore groove retaining according to demand.
The rod string that connects is owing to adopt the convex joint of the sucker rod body of rod and Baltimore groove grafting cooperation to form; there is the protection of screw thread hoop cover the outside; can bear bigger torsion, thereby improve the anti-twisting property of screw bolt well rod string, solve the dropout problem of screw bolt well rod string.
