Description
Technical field
The present invention relates to a kind of oil drill rocker and manufacture method thereof, particularly a kind of drilling rod and manufacture method thereof with higher anti-H 2 S stress corrosion performance belongs to the oil drill rocker technical field.
Background technology
Common oil drill rocker is according to the API standard production, and the main processes of its production is: the desired size thickening is pressed at the hot rolled seamless steel tube two ends, carry out whole modified thermal treatment then, make drill pipe body.Simultaneously on tool-joint, process internal and external screw thread, tool-joint is placed in the quenching furnance heat-treats then.Tool-joint after drill pipe body and the thermal treatment is connected through the friction butt welding, and butt welded seam is heat-treated again, makes oil drill rocker at last.
For a long time, the API drilling rod has obtained widely to use, but along with a large amount of exploitations in sour oil gas field, the API drilling rod has obvious defects under this operating mode.Acid oil gas Tanaka, hydrogen sulfide is important corrosive medium.H2S can cause metallic substance (material of oil drill rocker) that paroxysmal sulfide-stress cracking (SSC) takes place, thereby shortens the work-ing life of oil drill rocker greatly.
Find that by prior art documents the Chinese patent publication number is CN1715438A, open day is on January 4th, 2006, and the patent of invention name is called: resistant to carbon dioxide, chloride ion corrosion oil drill rocker steel.This patent readme is: a kind of oil drill rocker steel, particularly a kind of resistant to carbon dioxide, chloride ion corrosion oil drill rocker steel that contains under the compound corrosion working conditions such as moistening resistant to carbon dioxide, chlorion, vitriol.Solved the existing drilling rod anti-CO of steel
2, Cl
-The corrosive nature defect of bad.Resistant to carbon dioxide, chloride ion corrosion oil drill rocker steel, the weight percent of its moiety is: C:0.20-0.40, Si:0.10-1.0, Mn:0.10-1.5, Cr:1.0-4.0, Mo:0.10-1.0, Al:0.01-0.10, Cu:0.05-1.0, Ni:0.05-1.0, V:0.01-0.1, all the other are that Fe and unavoidable impurities are formed.Add the Nb of 0.01-0.05 and the W element of 0.01-0.10 in case of necessity, impurity element is that total amount is lower than 0.05%.Main as the oil drill rocker steel that contains under the compound corrosion working conditions such as moistening carbonic acid gas, chlorion, vitriol.
This patent has been considered the corrosive medium of resistant to carbon dioxide and two kinds of different in kinds of chlorion simultaneously, so steel grades design adds to the favourable Cr element of resisting chloride ion penetration with to the favourable Cu of resistant to carbon dioxide, trace elements such as Ni, Al.But because the content of harmful elements such as Si, Mn is higher in the steel grade, simultaneously harmful elements such as S, P are not had strict control, make that this steel grade anti-H 2 S stress corrosion performance is unsatisfactory.
In addition, what existing drilling rod adopted all is friction welding joint, in this case, even the anti-H 2 S stress corrosion performance of drill pipe body itself is improved, but at the position of joint and body welding, corrosion resistance is very poor, and this has also damaged the whole corrosion resistance of whole drilling rod.
Summary of the invention
The purpose of this invention is to provide a kind of anti-sulfur drill rod and manufacture method thereof, to satisfy the exploitation needs in sour oil gas field with higher anti-H 2 S stress corrosion ability.
In order to achieve the above object, the present invention adopts following technical scheme:
1) improve the chemical ingredients of sleeve pipe steel grade, the chemical ingredients that makes described sleeve pipe steel grade is except that Fe, and other composition is: C:0.25-0.38, Cr:0.80-3.80, Mo:0.15-0.65, V:0-0.08, Ti:0-0.06, B:0-0.06, Ni:0.10-0.35, Mn:0.40-0.90, Si:0.17-0.40, S:＜0.010, P:＜0.015.Unit is a mass percent.
In the above-mentioned chemical ingredients, C is that assurance drilling rod intensity and hardening capacity are necessary, and C content is too low, and then intensity and hardening capacity are not enough, too high then toughness variation.For the drilling rod of grade of steel from X95 to S135, C content can satisfy intensity and flexible requirement in the 0.25-0.38 scope.
Elements such as Ni, Mn, Si, S, P can be disadvantageous to the hydrogen sulfide corrosion resistance of material, belong to harmful element, will limit its content when design, and especially S, P content are wanted strict control.
To preventing H
2The useful unit of S corrosion have Cr, Mo, Ti, B etc., adding proper C r, Mo element can play the effect of crystal grain thinning, the Mo element can generate carbide in modified or normalizing Heat Treatment Of Steel, be easy to remove solid solution carbon, can also prevent the intercrystalline segregation of hazardous elements S i, P, element ti can improve the phase point temperature of steel, improves the hardening capacity of steel, is easy to form the tempered sorbite tissue of grain refining.
2) except strictness is controlled to chemical ingredients, need simultaneously the thermal treatment process of drilling rod is carried out strict regulation, must satisfy following the requirement: the thermal treatment process that adopts quenching+high tempering, quenchant is a water, quenching temperature is 860 ℃ ± 10 ℃, soaking time is no less than 20 minutes, and tempering temperature is more than 500 ℃, and soaking time is no less than 40 minutes.After the quenching, the steel pipe total cross section can obtain 98% above martensitic stucture.Behind the high tempering, form tiny, uniform tempered martensite, 8 grades of grain fineness numbers or more tiny.
3) joint adopts the integral joint of no-welding type, eliminates the disadvantageous effect of commissure to corrosion resistance.
Advantage of the present invention is: 1) performance of anti-H 2 S stress corrosion is good.Compared with prior art, this technology has adopted new steel grades design, has adopted more rational heat treatment technology simultaneously, thereby has had better hydrogen sulfide corrosion resistance energy; 2) overcome the defective of commissure corrosion resistance weakness, made the whole drilling rod that comprises joint all have good hydrogen sulfide corrosion resistance energy, can be used for making the various drilling rods of X95-S125.
