Abstract
An antiseptic and wear resistant sucker polish rod comprises a body of rod and nickel phosphor alloy cladding as composite on the ectotheca surface. In the utility model, the nickel phosphor alloy cladding composite on the ectotheca surface of the body of rod is plated on the ectotheca surface by chemical plating method. The chemical plating nickel phosphor alloy cladding has a strong cohesion with the rod matrix and a compact, uniform texture with high hardness and good corrosion resisting property. When being used in oil sucking, the utility model has the greatly improved wear and corrosion resisting property and two times prolonged service life compared with common sucker polish rods with the same matrix.
Description
Technical field
The utility model relates to a kind of oil pumping polish rod, particularly a kind of composite bed of oil pumping polish rod body of rod outer wall.
Background technology
In the sucker rod in the oilfield, topmost a sucker rod of drawing from the oil well mouth that links to each other with oil pumper is an oil pumping polish rod, and oil pumping polish rod has the body of rod, and there is the bar head at the two ends of the body of rod, on the bar head connecting thread are arranged.For the sealing of oil well mouth, the oil well mouth has the material filling type sealing shroud, and the material filling type sealing is with the closed hole that matches with the body of rod of oil pumping polish rod, be filled with packing in the material filling type sealing shroud, the body of rod of oil pumping polish rod stretches out from closed hole, and during oil pumping, the body of rod of oil pumping polish rod moves back and forth in closed hole.In the prior art, in order to help the sealing of oil well mouth, the surface of the body of rod of sucker rod will be done honing processing and handle, make the roughness Ra on body of rod surface be not less than 0.4m, because the pressure in the oil well is bigger, sealing load between material filling type sealing shroud and oil pumping polish rod is also bigger, contains H in the well liquid of extracting out from oil well

2The corrosion of O and other comprehensive corrosion factors, after use a period of time, oil pumping polish rod can lose efficacy because of denuding and corroding, the erosion resistant of this oil pumping polish rod and corrosion resistant poor-performing, application life is short.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose the anticorrosion antiwear oil pumping polish rod of a kind of erosion resistant and corrosion resistant better performances.
The utility model is realized with the following method.
The anticorrosion antiwear oil pumping polish rod has the body of rod, and the two ends of the body of rod have the bar head respectively, on the bar head connecting thread is arranged, and is compounded with nickel-phosphorus alloy coating in the outer wall surface of the body of rod.
The compound nickel-phosphorus alloy coating of the utility model body of rod outer wall surface is that the method with chemical plating is plated on the body of rod outer wall surface.
The utility model method with chemical plating on the surface of body of rod outer wall is compounded with ni-p alloy coating, the adhesion of the ni-p alloy coating of chemical plating and body of rod matrix is strong, the ni-p alloy coating quality is closely knit, even, hardness big, good corrosion resistance, in oil pumping is used, common oil pumping polish rod ratio with same matrix, erosion resistant, corrosion resistance are greatly improved, and can prolong more than two times application life.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is that schematic diagram cuts open in the master office of looking of anticorrosion antiwear oil pumping polish rod;
Fig. 2 is the A-A generalized section of Fig. 1.
The specific embodiment
Among Fig. 1, Fig. 2, the anticorrosion antiwear oil pumping polish rod has the body of rod 1, and the two ends of the body of rod have bar head 2,3 respectively, on the bar head connecting thread are arranged, and is compounded with chemical nickeling phosphorus alloy film 4 in the outer wall surface of the body of rod.
The thickness of the chemical nickeling phosphorus alloy film that above-mentioned oil pumping polish rod body of rod outer wall surface is compound can be 30～50 μ m.
