Abstract
The utility model relates to an anti-torque high-strength non-corrosive sucker rod, which comprises a rod body and a rod head. The sucker rod has the following characteristics: a rod head thread is tapered; besides the rod head thread, the whole sucker rod is provided with a chemical plating; and the deposition thickness of the chemical plating on the surface of the sucker rod is larger than or equal to 25Mu m. The sucker rod has the following advantages: the rigidity of the chemical plating of the sucker rod is high, and the anti-abrasion property of the chemical plating is good, so the chemical plating is better than an electroplated layer; since the tapered thread structure is adopted, the anti-torque property of the sucker rod is improved; and therefore, the sucker rod can be used in deep wells and corrosive wells.
Description
Technical field
The utility model relates to a kind of torque resistant super-high-strength anti-corrosion pumping bar, belongs to the used instrument of recover petroleum.
Background technology
Sucker rod is the required main tool of mechanical oil recovery, when selecting the screw pump deep-well oil-extraction for use, except that sucker rod being required should have the also requirement of intensity of superelevation to have bigger torsional property, bar surface also to want anticorrosion could guarantee instructions for use.
At present domesticly only can make common grade and high intensity levels sucker rod by industry standard, use in deep-well and corrosion well, the life-span is too short maybe can not use, and does not satisfy the instructions for use in oil field.
Technology contents
The purpose of this utility model provides that a kind of abrasion resistance properties is good, torsional property is high, can satisfy the torque resistant super-high-strength anti-corrosion pumping bar of the requirement of using in deep-well and corrosion well.
The purpose of this utility model is realized by following technical scheme:
The utility model comprises the body of rod, bar head, it is characterized in that: the bar head thread partly is taper thread, and except that threaded portion, sucker rod integral body has chemical deposit, and chemical deposit is at sucker rod surface deposition thickness 〉=25 μ m.
The utility model has the advantages that: sucker rod coating hardness height, abrasion resistance properties is good, is better than electrodeposited coating, selects the taper thread project organization for use, has improved the torsional property of sucker rod, can satisfy the requirement of using in deep-well and corrosion well.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a body of rod sectional drawing.
The specific embodiment
With reference to accompanying drawing 1, Fig. 2, the utility model comprises the sucker rod body of rod 1, bar head 2, and bar head thread 3 is a taper thread.For improving the mechanical performance of sucker rod, the senior superior alloy steel of raw material selection is heat-treated by the super-strength sucker rod rank, makes it reach superhigh intensity rank and torque resistant index.Taper thread 3 is selected the NC style connection thread structure for use, screw thread code name NC-13, and form of thread V-0.0055, tapering are 1: 8, this structure can be born bigger circumferential moment of torsion.Sucker rod surface integral body utilizes electroless deposition that the nickel-phosphor alloy coating 4 of thickness 〉=25 μ m is arranged except that threaded portion, and this layer has antiseptic property and can make the body of rod and the medium isolation, and sucker rod is not corroded.
Claims (3)
1. a torque resistant super-high-strength anti-corrosion pumping bar comprises the body of rod, bar head, it is characterized in that: the bar head thread partly is taper thread, and except that threaded portion, sucker rod integral body has chemical deposit, and chemical deposit is at sucker rod surface deposition thickness 〉=25 μ m.
2. torque resistant super-high-strength anti-corrosion pumping bar according to claim 1 is characterized in that: described chemical deposit is a nickel-phosphor alloy coating.
3. torque resistant super-high-strength anti-corrosion pumping bar according to claim 1 is characterized in that: bar nose cone screw thread is the numeric type taper thread, screw thread code name NC-13, and form of thread V-0.0055, tapering are 1: 8.
