Abstract
The invention discloses a nano coating corrosion prevention pipe which comprises a pipe body, iron-aluminum multicomponent alloy layers and pure alloy layers, wherein the iron-aluminum multicomponent alloy layers are coated on the inner wall and the outer wall of the pipe body, the pure alloy layers are arranged on arc surfaces of the iron-aluminum multicomponent alloy layers, which are far away from the pipe body; and inner walls or outer walls of the pure alloy layers as the corrosion prevention pipe are also provided with nano polymer coatings. The nano coating corrosion prevention pipe has the advantages of better corrosion resistance performance, large bonding force, good mechanical property and ageing resistance, and better wax scale prevention effect.
Description
Technical field:
The present invention relates to oil recovery field, oil field used a kind of oil pipe or sleeve pipe, belong to a kind of nanometer coating pipe that is used for oil gas field.
Background technique:
Adopt oil pipe or sleeve pipe to come liquid is transported during oil recovery, oil pipe or sleeve pipe burn into perforation phenomenon can occur in long-term use, cause oil pipe or sleeve pipe not to reach and promptly can not re-use service life.And on-the-spot present applied tubing and casing anti-corrosion method is surperficial separation layer method, can only play the effect of temporary transient isolation environment aggressive 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 working 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 working life; The present invention provides a kind of nano coating anti-corrosion pipe; This anti-corrosion pipe not only has excellent corrosion resisting performance, big, the good mechanical property, anti-aging of combination force, but also has the advantage of strong wax-proof anti-scaling.
The technological scheme that the present invention taked is: the nano coating anti-corrosion pipe; Comprise tube body, iron aluminium multicomponent alloy layer, pure alloy-layer; Described tube body inside and outside wall is coated with iron aluminium multicomponent alloy layer; Described iron aluminium multicomponent alloy layer is provided with pure alloy-layer away from the arc surface of tube body, and described pure alloy-layer also is provided with the nanometer polymer coating as the inwall or the outer wall of anti-corrosion pipe.
The thickness of described nanometer polymer coating is 90～120 μ m.
The invention has the beneficial effects as follows: the multicomponent alloy layer of this nano coating anti-corrosion pipe has the stainless steel characteristic, and form metallurgical chemistry between coating or plating layer and combine, strong adhesion, and have the anode loss protection effect, have higher mechanical strength and corrosion resistance; Simultaneously, anti-corrosion pipe is purified again, carry out nanometer and gather the coating rotary spraying; This tube surfaces light, smooth, free of pinholes, non-scaling, not sticking oil; But dielectric corrosions such as acid-and base-resisting, salt, surface active agent, sewage, rock gas, microorganism; Have anticorrosion, antiscale, wax control and anti-delamination four anti-characteristics.
Description of drawings:
Accompanying drawing 1 is the structure sectional view of the embodiment of the invention one;
Accompanying drawing 2 is structure sectional views of the embodiment of the invention two.
Sequence number among the figure: 1, tube body, 2, iron aluminium multicomponent alloy layer, 3, pure alloy-layer, 4, the nanometer polymer coating.
Embodiment:
To be described further the present invention below in conjunction with accompanying drawing:
Embodiment one: by shown in Figure 1; A kind of nano coating anti-corrosion pipe; Comprise tube body 1, iron aluminium multicomponent alloy layer 2, pure alloy-layer 3, 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; 3 described pure alloy-layers 3 also are provided with nanometer polymer coating 4 as the inner and outer wall of anti-corrosion pipe, and the thickness of described nanometer polymer coating 4 is 90～120 μ m.
Embodiment two: by shown in Figure 2; A kind of nano coating anti-corrosion pipe; Comprise tube body 1, iron aluminium multicomponent alloy layer 2, pure alloy-layer 3, 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; 3 described pure alloy-layers 3 also are provided with nanometer polymer coating 4 as the inwall of anti-corrosion pipe, and the thickness of described nanometer polymer coating 4 is 90～120 μ m.
This nano coating anti-corrosion pipe has good corrosion resistance, and can guarantee the construction, the transportation process 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, gas well and CO2 injection extraction well etc.
