Description
Technical field
The present invention relates to the steel field, particularly relate to a kind of steel and application thereof.
Background technology
Oil pipe, oil well casing, sucker rod, oil well pump and the ground transport pipes etc. that use in the oil-gas field well of countries in the world exploitation all stand salt, chlorion, carbonic acid gas, hydrogen sulfide, sulfide, acid, alkali for a long time, contain the strong corrosion of the multiple corrosive mediums such as water of corrosive compound, reach the powerful wearing and tearing of tempering property particulate such as sand grains, therefore, annual consumptions such as oil pipe, oil well casing, sucker rod, oil well pump are all very huge, the cost of winning height, resource, energy consumption are big, are unfavorable for the development of low-carbon (LC) green economy.How to solve the heavy corrosion and the wear problem of oil pipe, oil well casing, sucker rod, oil well pump and the ground transport pipe etc. that use in the oil-gas field well, how to improve and prolong its work-ing life, it is the problem of countries in the world scientific research department research always, address this problem effectively and just seem very necessary, and be imminent.
In recent years, in the countries in the world with the production in oil field, relevant colleges and universities and R﹠D institution and some incorporated businesses of exploitation, carried out number of research projects for the heavy corrosion and the wear problem that how to solve employed oil pipe in the oil-gas field well, oil well casing, sucker rod, oil well pump and ground transport pipe etc., comprised how research improves the bulk properties of material and the reinforcement performance of material surface etc.
Reinforcement aspect of performance on the research material surface, result of study comprise chronizing oil pipe, pulse Vacuum nitrogenize anti-corrosion pumping bar, plate and ooze tungsten-bast alloy anti-corrosive abrasion-proof oil conduit sucker rod (DSW), spraying tungstenalloy anticorrosive abrasion-proof sucker rod, AOC anti-corrosion pumping bar, nano anti-corrosive sucker rod or the like.The common feature of existing these anti-corrosion pumping bars is that top coat is anticorrosion, and as diffusion coating, plating infiltration layer, and sprayed coating is a surface strengthening technology and these coatings all adopt.This anti-corrosion measure can bring good preservative effect and long work-ing life for part, member or the device that bears static load, and can only play preservative activity preferably for bearing the repeated load component in certain working hour.Because the mechanical property of surface anticorrosion coating always there are differences with the mechanical property of bulk material, cause the strain of the strain of adopting top coat rot-resistant component its top layer under the effect of repeated load and body inconsistent, therefore, when load to this type component alternation after effect for some time, coating will crack or peel off with body and come off, at this moment, the corrosion speed of body will significantly be accelerated and occur losing efficacy.Obviously, the bulk properties that improves material solves heavy corrosion and the wear problem that uses in the oil-gas field well, is a kind of both economical and reasonable method approach.
Aspect the bulk properties of research raising material, domestic superstrength, the bainite type, high-strength non-hardened and non-tempered developed once with steel etc., though the mechanical property of material satisfies the service requirements of oil-gas field well, corrosion resistance nature improves little, restricts their large-scale application.In addition, also develop common austenitic stainless steel, it is essential type impregnating material, is widely used in industries such as chemical industry, pharmacy.But, its use range is restricted because its strength property is generally all low than common steel alloy.Once development and production go out the steel alloy of several high-strength corrosion-resistings in earlier 1990s in the U.S., and its performance is very good, but its price is very expensive, are difficult to large-scale popularization application on oil-gas field well development engineering.Generally adopt in the world and add elements such as to improve thermodynamics of alloys Cr, Ni stable and directly retardance anodic process, Mo; as Mo18-Ni40 nickel-base alloy, Ni22-25Cr stainless steel etc.; make the very fast sealer corrosion structure that forms high stable alloy constituent element of material surface with one or several atomic layer level thickness; but; the price of Cr, Ni, Mo element is higher, and add-on surpasses the significantly production cost of increase material of 3%Mo, 5%Ni, 18%Cr.
Oil-gas field wells such as the Cr13 iron of the 10Cr3MoNi of domestic-developed and remodeling, its erosion resistance all is greatly improved with steel than conventional oil gas field wells such as 20CrMoA, but, in multiple corrosive mediums such as sulfide hydrogen, it is poor that its anticorrosion effect just seems, according to SY 5329-1994 " petroclastic rock reservoir water water quality proposed standard " People's Republic of China's oil and gas industry standard, the corrosion speed of 10Cr3MoNi material reaches 0.7634mm/a, and the corrosion speed of the Cr13 material of remodeling reaches 0.2564mm/a.
Summary of the invention

The Corrosion Protection test: according to SY 5329-1994 " petroclastic rock reservoir water water quality proposed standard " People's Republic of China's oil and gas industry standard, test condition sees Table 2, and test result sees Table 3.
For the Corrosion Protection of the steel of identity basis embodiment of the invention 1-7 made better, two kinds of Comparative Examples are provided below, and under as table 2 test condition, have carried out the Corrosion Protection test respectively.
Table 2 simulation oil field test medium is formed (g/L)
Table 3 high-temperature high-pressure anti-corrosive performance test result
By data in the table 3 as can be known by the prepared steel of the present invention under the simulation oil field environmental applications, erosion rate is starkly lower than standard value, the weight loss in the use reduces, under equal conditions, steel provided by the present invention can be corrosion-resistant better, wear-resistant, increases its work-ing life.
In sum, steel provided by the present invention have not only strengthened the mechanical property of steel, and have improved the high anti-corrosive medium of steel significantly, have prolonged the work-ing life of steel.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
