The chemical composition of material described in the present invention and the principle of design of mass percent as follows.
In deep-well construction process, the stress that drilling rod bears is very complicated, comprises tensile, compressive, bending, turns round, shears and compound and repeated load etc., easily causes the fatigure failure of drilling rod; Meanwhile, in deep-well construction, very high to the rotation speed requirements of drill string, and the too fast reversed of stress frequency that can increase of drilling speed, thus reduce the fatigue lifetime of drilling rod; In addition, according to mechanical vibration theory, when rotating speed overlaps with drill string natural frequency, drill string just resonates, and when occurring when resonating, drilling rod is new and old all can be very fast tired.Therefore, at present in deep-well construction process, the accident that drilling rod lost efficacy gets more and more.According to statistics, the accident of annual drilling string failure has 1000 example left and right, wherein causes the accident of drilling string failure to account for 50% ~ 60% of drilling string failure accident because drilling rod lost efficacy.
Existing theory, experiment and production practice all show, material Fatigue Failure Process under repeated load mainly contains two steps, and one is the germinating of fatigue cracking, and two is expansions of fatigue cracking.The time of fatigue crack initiation process account for 80% of whole Fatigue Failure Process total time.If the germinating time of fatigue cracking can be become sufficiently long, the ability that the antifatigue that just can improve material is to a great extent destroyed.According to the theory about material fatigue life up-to-date at present, think that the germinating process in fatigue cracking source of material is the process of damage accumulation.In the process, be first form FATIGUE SHORT CRACK GROWTH, short crack polymerization is final forms fatigue cracking source.According to up-to-date achievement in research, when certain energy input, the length of FATIGUE SHORT CRACK GROWTH concentrates near the grain-size of material, and the length of FATIGUE SHORT CRACK GROWTH, only when increasing input energy, just may continue to grow up to two grain sizes.Reason is in this process, and crystal boundary makes crack propagation be hindered.And continuing to increase and be polymerized, the crackle that final formation is large of these short cracks, become fatigue cracking source, accelerate expansion.So think that the anti-fatigue performance impact of grain-size on material is very large, grain-size is less, and anti-fatigue performance is better.In addition, topmost germinating place of fatigue cracking is the defect produced in second-phase in material and processing and manufacturing process, therefore, in the manufacture and heat treatment process of material, make the second phase particles in material little as far as possible, and glomeration, to reduce its surface energy, and avoid as much as possible producing surface imperfection.
In order to solve the problem, the embodiment of the present invention is passed through to add rare earth element ce and the content controlling other chemical compositions, namely the formula adjusting 150 steel grade drill pipe materials carrys out crystal grain thinning, make second phase particles glomeration, thus improve the obdurability coupling of described drill rod materials, improve the anti-fatigue performance of material, extend fatigue lifetime.
Specific explanations is as follows:
In the embodiment of the present invention, C is austenite former, the effect that minimizing is the consumption of the Ni of austenite former equally can be played containing C, but above-mentioned DeGrain when C content is too low, also the intensity of material is damaged, C is also carbide forming element, can improve the intensity of steel containing C, but high-content C is easily formed containing the thick M of Cr particle
23c
6type carbide, reduces anti-SSC performance and the impelling strength of steel.For taking into account strength and toughness, C addition of the present invention is 0.23 ~ 0.30%.
In the embodiment of the present invention, Mn cost is lower, has the effect improving hardening capacity and improved ferrite intensity by solution strengthening.But Mn content cross manganese alloy cementite can be caused at most too much be distributed in crystal boundary, reduce toughness of material.
Rare earth element ce is with the addition of in the embodiment of the present invention.Rare earth element ce can cleaning molten steel, reduces the segregation of P on crystal boundary, eliminates Fe
3p weakens the deleterious effect of crystal boundary, and strengthening grain boundary state, forms spherical oxysulfide simultaneously.This compound hardness, higher than MnS, can not be strip distribution along rolling direction when rolling, avoid stress concentration, improve intensity, toughness and fatigue strength.Rare earth element ce can promote that the microalloy element being solid-solution in austenitic area is separated out in ferrite area simultaneously, improves the utilization ratio of microalloy element.The microalloying mechanism of rare earth element ce has a certain impact to the mechanical property of drill rod materials, improves the purity of drilling rod steel, the harmful element content such as P, S, O, N are down to minimum.In addition, adding of rare earth element ce makes inclusion spherical in shape, the tiny branch of further disperse; Many alloy cpds disperse educt, effectively prevents germinating and the expansion of fatigue cracking.
In the embodiment of the present invention, Nb separates out tiny carbide in austenitic area, by Grain boundary pinning effect restrain grain growth, crystal grain thinning, recrystallization temperature and grain coarsening temperature can be improved at the Nb of recrystallization zone solid solution simultaneously, be conducive to making grain deformation then be recrystallised to tiny crystal grain by controlled rolling.The precipitation of tiny carbide simultaneously is also conducive to the intensity improving steel.The effect that Nb improves obdurability by microalloying is the strongest, effectively improves intensity 150Mpa simultaneously.Rare earth and Nb combine the amount of precipitation that doping can significantly improve Nb carbide simultaneously, reduce carbide size, are conducive to the effect improving grain refining and dispersion-strengthened.
On the other hand, the invention provides the preparation method of the tough 150 steel grade drill pipe materials of a kind of above-mentioned height, the preparation method of described material comprises:
The manufacturing processed of material and the heat treatment process of material, first carry out melting and continuous casting to described material, then through extrusion tube blank or pierced billet pipe, be rolled into body, finally carry out body thermal treatment.
Further, described body thermal treatment comprises Quench and temper.
Described quenching is specially water quenching.
Further, need after being rolled into body described in carry out sizing and aligning.
Described sizing specifically comprises the expanding and thermotension tube reducing of thermotension.
The beneficial effect that the technical scheme that the embodiment of the present invention provides is brought is: by adding rare earth element ce, having purified molten steel, having decreased the segregation of P on crystal boundary, eliminate Fe
3p weakens the deleterious effect of crystal boundary, strengthening grain boundary state; In addition, rare earth element ce and element nb combine the amount of precipitation that doping can significantly improve Nb carbide, reduce carbide size, improve the effect of grain refining and dispersion-strengthened.The formation of spherical oxysulfide simultaneously, makes material can not be strip distribution along rolling direction when rolling, avoids stress concentration.Gained 150 steel grade drill pipe material of the present invention is on the basis of mechanical property meeting all API standards, and be under the condition of yield strength 80% at fatigue stress peak value, tired cycle is 10
7, anti-fatigue performance is improved, and fatigue lifetime obtains prolongation; Apply the drilling rod that the tough 150 steel grade drill pipe materials of above-mentioned height manufacture, in the underground deep layer operations such as oil production, geological prospecting and deep-well excavation, be more applicable to day by day harsh equipment military service operating mode.
