In the oil well asked.
The content of the invention
For the deficiencies in the prior art, one kind that the present invention is provided is at 400 DEG C or higher
The thermal production well oil well pipe and its manufacture method of the excellent performance used under temperature environment, to meet
Instantly and future market is to the use requirement of high-fire resistance energy oil well pipe.
The present inventor had found by substantial amounts of experimental study, the intensity under the conditions of oil well pipe high temperature resistant
Fade performance with chemical composition except having outside the Pass, and also relevant with manufacturing process, it is substantially steel
Strengthening mechanism and degree of grain refinement are playing a decisive role.The present invention is using high C, low Cr, nothing
Mo, W composition design route, implement the Technology for Heating Processing of seamless tubulation+special, finally obtain
Obtain the thermal production well oil well pipe of the excellent performance used under 400 DEG C or higher temperature environment.
The present invention overall technological scheme be：Based on the high Mn steel of high C, addition Cr,
The alloy design of Ti, Nb alloying, the cost of alloy of product is relatively low, it is easy to accomplish industrialization
Batch production.The design of alloy of steel, by weight percentage for：C 0.36%~0.60%,
Si 0.46%~0.70%, Mn 1.60%~1.80%, P≤0.025%, S≤0.015%, Cr
1.6%~1.8%, Nb 0.01%~0.03%, Ti 0.01%~0.03%, surplus are Fe and can not
The impurity avoided.
The effect of each essential element and design reason are as follows：
C：The quenching degree of steel is improved, and carbide is formed with metallic element, it is enough to obtain
Intensity, content is too low not to reach desired intensity, and content is too high then to increase the brittle property of product,
To achieve the object of the present invention, C content scope is limited as 0.36%~0.60%.
Si：On the one hand deoxidation is played, the elastic limit of steel on the other hand can be improved, improved
The Properties of High Temperature Creep of steel, content is too low not to have positive effect, and content is too high, damages steel
Modeling, toughness, to achieve the object of the present invention, limit Si content ranges as 0.46%~0.70%.
Mn：On the one hand deoxidation is played, on the other hand expands between austenitic area, increases supercooling
Stabilization of austenite, improves the quenching degree of steel, also helps the refinement of steel crystallite dimension.But
The segregation tendency of steel can be increased during Mn too high levels, internal flaw is also easy to produce, considers,
The present invention limits Mn content range 1.60%~1.80%.
Cr：Combined closely in steel with C, form tiny carbide, improved quenching degree, carry
High resistance to tempering, improves the intensity of steel, the especially intensity under high temperature, but easy during too high levels
The Forming Mechanism of carbide is changed, cause the coarsening of Cr carbide.To reach this
The purpose of invention, limits Cr content range 1.6%~1.8%.
Nb：C, N compound are formed, the effect with crystal grain thinning, raising intensity and toughness,
The quenching degree and resistance to tempering of steel can be improved, Properties of High Temperature Creep is improved, but content is unsuitable
It is too high, otherwise increase the imperfection sensitivity of steel.To achieve the object of the present invention, limit Nb's
Scope is 0.01%~0.03%.
Ti：The crystal grain mainly formed in compound limitation hot procedure is grown up, and is obtained tiny
Grain structure, improve strong, the toughness of steel, moreover, fixed free N, C atom, has
Beneficial to the elevated temperature strength performance for improving steel.But content is too high, its effect will not substantially, Er Qiezeng
The difficulty of casting is smelted in addition sheet, again increase, is unfavorable for industrializing implementation.To realize the present invention
Purpose, limit Ti content range 0.01%~0.03%.
P、S：For harmful element main in steel, the toughness and comprehensive mechanical property of steel are reduced,
It is more low better it is generally desirable to content, but cost can be increased, consider, present invention restriction P≤
0.025%th, S≤0.015%.
High temperature resistant thermal production well of the present invention is with the manufacture method of oil well pipe：By above-mentioned chemical composition
Steel by converter smelting+round billet manufacture+seamless tubulation+special Technology for Heating Processing.
Round billet and steel pipe are manufactured using hot rolling technology, suitable heating-up temperature 1240~1300 is chosen
DEG C, 1050~1150 DEG C of tubulation temperature, according to can also be to above parameter model the need for properties of product
Enclose further optimization to reduce, i.e. 1260~1280 DEG C of heating-up temperature, tubulation temperature 1080~1100
℃；By special Technology for Heating Processing, the tissue, crystal grain and carbide of steel pipe is set to obtain finely
With homogenization.
The Technology for Heating Processing of steel pipe of the present invention is as follows：Steel pipe after shaping is at 980~1000 DEG C
Temperature range is incubated 4~15s, rapid to carry out the cooling that cooling rate is more than 130 DEG C/s, is cooled to 200~300
DEG C temperature range carries out 20~40min of constant temperature, and room temperature is cooled to afterwards.
In the production technology of the present invention：
Choose higher heating-up temperature, tubulation temperature, can by C, Si, Mn, Cr, Nb,
V is completely dissolved in austenite, provides guarantee for follow-up disperse educt, and steel pipe is become
Shape is more smooth, reduces deformation drag, beneficial to being smoothed out for industry manufacture.Therefore, this hair
Bright that the heating-up temperature of round billet is defined as into 1240~1300 DEG C, tubulation temperature specifications are
1050~1150 DEG C.
After shaping the selection of temperature of steel pipe and soaking time be in order that austenite full and uniformization,
And the precipitation of pro-eutectoid tissue is avoided, product overall performance is influenceed, meanwhile, there is austenite
Preferable quenching degree, is easy to be combined the generation technology to be reached effect with subsequent heat treatment technique
Really.Therefore, the present invention by temperature of steel pipe after shaping and soaking time respectively provide for
980~1000 DEG C and 4~15s.
Steel pipe quickly cool down after shaping and progress constant temperature insulation is critically important, and cooling rate is too slow, difficult
To ensure stability of the overcooling austenite before thermostat temperature is reached, produce be not intended to obtain F,
P class loadings, therefore cooling velocity is defined to 130 DEG C/more than s by the present invention.
The limit temperature of constant temperature insulation can make austenite whole in 200~300 DEG C of temperature ranges
It is changed into lower bainite, is that the technique effect required for the present invention reaches serves final guarantor
Card.
Resulting product has following performance characteristic.
Resistance to elevated temperatures：400 DEG C of instantaneous stretching yield strength >=862MPa；By 510h's

Beneficial effect：
1st, the present invention is without W, Co, and the expensive metal such as Mo is multiple using the high Mn of high C
Close addition Cr, Nb, Ti and implement intensive Alloying Design, manufacture 400 DEG C or higher temperature
The thermal production well oil well pipe used under environment, solve thermal production well with resistance to 400 DEG C of oil well pipe tubing or
The technical barrier that intensity heat loss fails under higher temperature environment, and cost of alloy is moderate, belongs to
Thermal production well is pioneering with oil well pipe composition design.
2nd, using pneumatic steelmaking base+seamless steel pipe shaping and special Technology for Heating Processing route,
Temperature is between 980~1000 DEG C after the shaping of period control steel pipe, and implements quickly to cool down,
The precipitation of alloy carbide is limited, product is played when using at high temperature and improves resistance to tempering
Effect.
3rd, the preferential special thermal treatment technique using not offline, i.e., using online rapid cooling isothermal tissue
The technique productions high temperature heat-resistant oil recovery well casing of transformation, the creep of product high temperature resistant and anti-strength retrogression's property
