Abstract
The utility model relates to an anticorrosive magnetic stripe of a magnetic-force-supported sucker rod centralizer. The anticorrosive magnetic stripe comprises a magnetic stripe. The magnetic stripe is trapezoidal and the section of the magnetic stripe is rectangular. The external part of the magnetic stripe is covered by a nonmetallic material layer. The nonmetallic material layer is molten and cast on the magnetic stripe. The thickness of the nonmetallic material layer is 0.2-1.5mm. The nonmetallic material layer is not corroded by well fluid. The magnetic stripe on the magnetic-force-supported sucker rod centralizer is not in contact with corrosive media. Therefore, the magnetic stripe is not corroded, the service life of the magnetic-force-supported sucker rod centralizer can be prolonged, the service life of a sucker rod and an oil pipe can be prolonged and the economic benefits are remarkable.
Description
Technical field
The utility model relates to the oil production equipment of petroleum industry, is the anticorrosion magnetic stripe of a kind of magnetic support pumping rod centralizer.
Background technology
Chinese patent application: the upper employing of 200820187876.1 " magnetic support pumping rod centralizers " magnetic stripe will install and relatively be fixed on tube inner wall, make it to form friction pair with sucker rod and prevent sucker rod and oil pipe eccentric wear, but magnetic stripe is not corrosion-resistant, in well longevity of service will be corroded, generation comes off, the magnetic stripe that causes sucker rod to be come off blocks, sucker rod can not be moved in oil pipe, can't pump, cause that oil well stops production, also can cause the oil pumper excess load, cause security incident, also can cause the sucker rod excess load to produce and damage.
Summary of the invention
The purpose of this utility model is the anticorrosion magnetic stripe of a kind of magnetic support pumping rod centralizer of design, avoids magnetic stripe to be corroded, and improves the useful life of magnetic support pumping rod centralizer, thereby improves the useful life of sucker rod, oil pipe.
The purpose of this utility model has been achieved in that magnetic stripe, and it is trapezoidal that magnetic stripe is, and cross section is rectangle, in the outside of magnetic stripe, coats the non-metallic material bed of material, and the non-metallic material bed of material melts casting on magnetic stripe, and the thickness of the non-metallic material bed of material is 0.2-1.5mm.
The beneficial effects of the utility model are: the non-metallic material bed of material can be by the well corrosion, magnetic stripe on magnetic support pumping rod centralizer does not contact with Korrosionsmedium, therefore magnetic stripe can not be corroded, can improve the useful life of magnetic support pumping rod centralizer, thereby can improve the useful life of sucker rod, oil pipe, there is significant economic benefit.
The accompanying drawing explanation
Fig. 1 is complete section figure of the present utility model.
Fig. 2 is the sectional drawing after cutting open from A-A in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in the figure, magnetic stripe 1 is arranged, magnetic stripe 1 is trapezoidal, can not come off after being arranged on device, and cross section is rectangle, in order to form S, the N utmost point, outside at magnetic stripe 1 coats the non-metallic material bed of material 2, and the non-metallic material bed of material 2 melts casting on magnetic stripe 1, and the thickness of the non-metallic material bed of material 2 is 0.2-1.5mm, this thickness does not affect the magnetic of magnetic stripe, can be arranged on smoothly in the dovetail groove on device yet.
