Abstract
The invention discloses an anticorrosion pipe provided with alloy layers. The anticorrosion pipe comprises a pipe body, wherein a Fe-Al multielement alloy layer is respectively coated on the inner wall and the outer wall of the pipe body, and a circular-arc surface of the Fe-Al multielement alloy layer, which is away from the pipe body, is provided with a pure alloy layer. The anticorrosion pipe not only has favorable anticorrosion performance, large bonding force, good mechanical property and ageing resistance, but also has the advantages of strongly preventing wax and scale.
Description
Technical field:
The present invention relates to oil recovery field, oil field used a kind of oil pipe or sleeve pipe, relate in particular to a kind of anti-corrosion pipe that is provided with alloy-layer.
Background technology:
Adopt oil pipe or sleeve pipe to come liquid is transported during oil recovery, burn into perforation phenomenon can appear in oil pipe use for a long time, causes oil pipe or sleeve pipe not to reach and promptly can not re-use service life.Applied oil pipe of prior art or casing tube anti-corrosive method are surperficial separation layer method, can only play the effect of temporary transient isolation environment corrosive medium, along with the prolongation of service time; Anticorrosive coat then begins the gas-bearing formation obscission to occur, causes the aggravation of oil pipe or casing corrosion, and surperficial separation layer is mainly the epoxy resin type coating simultaneously; These epoxy resin type coatings exist water absorption rate high, and anti-mechanical shock, anti-machinery scratch the problem of poor performance, and anticorrosive coat can damage when construction and carrying; Have a strong impact on antiseptic effect; Reduced the application life of oil pipe, and the wax control of these separation layers, anti-scaling property are poor, cause tubing and casing wax deposition, scale formation serious; Shorten the maintenance interval of tubing and casing, cause suitable economic loss.
Summary of the invention:
In order to overcome short deficiency of existing oil pipe or casing tube anti-corrosive, wax control, antiscaling effect difference and application life; The present invention provides a kind of anti-corrosion pipe that is provided with alloy-layer; This anti-corrosion pipe not only has excellent corrosion resisting performance, big, the good mechanical property, anti-aging of adhesion, but also has the advantage of strong wax-proof anti-scaling.
The technical scheme that the present invention taked is: be provided with the anti-corrosion pipe of alloy-layer, comprise tube body, described tube body inside and outside wall is coated with iron aluminium multicomponent alloy layer, and described iron aluminium multicomponent alloy layer is provided with pure alloy-layer away from the arc surface of tube body.
The thickness of described iron aluminium multicomponent alloy layer is 80～120 μ m.
The invention has the beneficial effects as follows: the multicomponent alloy layer of this oil pipe or sleeve pipe has the stainless steel characteristic, and form metallurgical chemistry between coating and combine, strong adhesion, and have the anode loss protection effect, have higher mechanical strength and corrosion resistance; This tube surfaces light, smooth, free of pinholes, non-scaling, not sticking oil; But dielectric corrosions such as acid and alkali resistance, salt, surfactant, sewage, natural gas, microorganism; Have anticorrosion, antiscale, wax control and anti-delamination four anti-characteristics.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present invention.
The 1-tube body, 2-iron aluminium multicomponent alloy layer, the pure alloy-layer of 3-.
The specific embodiment:
To be described further the present invention below in conjunction with accompanying drawing:
By shown in Figure 1; A kind of anti-corrosion pipe that is provided with alloy-layer; Comprise tube body 1; Described tube body 1 inside and outside wall is coated with iron aluminium multicomponent alloy layer 2, and described iron aluminium multicomponent alloy layer 2 is provided with pure alloy-layer 3 away from the arc surface of tube body 1, and the thickness of described iron aluminium multicomponent alloy layer 2 is 80～120 μ m.
This oil pipe or sleeve pipe have good corrosion resistance, and can guarantee the construction, the transportation outer surface not aliquation, do not come off; Be mainly used in and gather displacement of reservoir oil well, ternary displacement of reservoir oil well, injection gas displacement gas well, deep-etching, strong fouling well, serious waxing in production well, the natural gas well and CO2 injection extraction well etc.
Claims (2)
