Description
Technical field
The invention belongs to oil country tubular goods technical field, be specifically related to a kind of for the resistance to CO of hp-ht well
2+ Cl
-the high-strength 15Cr oil pipe of corrosion.
Background technology
Along with growing to hydrocarbon resources demand of the world, impel the exploitation of oil-gas field to develop in depth gradually.It is very common that the Oil/gas Well that some 7600m are even darker becomes, thereby continue to bring out super dark superelevation kill-job.Continuing to bring out of high pressure-temperature, high pressure high temperature well causes exploratory development difficulty to increase gradually, bore completion problem showed increased, the completion problem that it faces has comprised the series of problems such as design, technique, instrument, equipment, well control, reservoir reconstruction, safety and the material selection of oil well, and its core is that the material of completion tubular column is selected problem.Because high pressure-temperature, high pressure high temperature well generally contain CO
2, H
2s and Cl
-, harsh bottom temperature, pressure and corrosion working condition are in the urgent need to using high-intensity anti-corrosion oil country tubular goods.According to corrosive gases component (H in temperature, pressure, flow velocity and air-flow
2s and CO
2), completion tubular column material range of choice can be from carbon steel and low alloy steel to stainless steel and nickel-base alloy etc.The temperature limitation that 13Cr Martensite Stainless Steel and super 13Cr Martensite Stainless Steel use is respectively 150 DEG C and 170 DEG C, and its resistance against sulfide stress cracking (SSC) or stress corrosion crack (SCC) performance extreme difference; Duplex stainless steel, nickel-base alloy tubing are at high pressure-temperature CO
2+ H
2s+Cl
-in environment, there is good anti-uniform corrosion, local corrosion and SCC ability, but because duplex stainless steel and nickel-base alloy tubing mainly improve intensity by cold working (rolling or drawing), under hot conditions, its strength retrogression is comparatively serious, as from room temperature to 200 DEG C, the yield strength of the 22Cr duplex stainless steel of the austenite-ferrite base about 200MPa(room temperature yield strength that declines is 125Ksi grade of steel), be about 2 times of Martensite Stainless Steel.Meanwhile, select duplex stainless steel and nickel-base alloy oil pipe material at high pressure-temperature, high pressure high temperature well, one-time investment is too large, and its cost is about 5 times of Martensite Stainless Steel oil pipe material, shaft building high cost.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of this invention is to provide a kind of for the resistance to CO of hp-ht well
2+ Cl
-the high-strength 15Cr oil pipe of corrosion, for High Temperature High Pressure, high containing CO
2+ Cl
-oil/gas Well uses, to overcome the height existing in existing High Temperature High Pressure oil gas well completion and production process containing CO
2+ Cl
-corrosion, solves the shaft building high cost problem for avoiding tube corrosion must adopt duplex stainless steel or nickel-base alloy oil pipe material to bring.
For achieving the above object, the technical solution used in the present invention is: a kind of for the resistance to CO of hp-ht well
2+ Cl
-the high-strength 15Cr oil pipe of corrosion, includes following component, by weight percentage:
Carbon≤0.03wt%, silicon 0.2～0.5wt%, manganese 0.2～0.6wt%, phosphorus≤0.02wt%, sulphur≤0.005wt%, chromium 14.5～15.3wt%, molybdenum 1.7～2.4wt%, copper 0.6～1.0wt%, nickel 6.1～6.9wt%, tungsten 0.4～0.7wt %, titanium 0.002～0.007wt%, boron 0.001～0.005wt%, niobium: 0.04～0.09wt%, vanadium 0.03～0.07wt%; Nitrogen 0.01～0.1%; Oxygen≤0.001 wt %; Hydrogen≤0.000005wt%, controlled composition is: arsenic≤0.03wt%, tin≤0.03wt%, antimony≤0.03wt%, surplus is iron.
Compared with existing common API 13Cr technology, advantage of the present invention is:
1) adopt Ultra-low carbon design, reduce to the carbide of separating out into chromium about 0.03wt.% with the Cr element in inhibition matrix by carbon content;
2) on the Cr of 15Cr, Ni Composition Design, than common API 13Cr and super 13Cr, consider its intensity and corrosion resisting property, improved the corrosion proof while of 15Cr oil pipe material that (higher Ni content, is of value to the stainless anti-SSC of 15Cr and the SCC ability of improving; The raising of Cr content contributes to improve anti-uniform corrosion and the spot corrosion ability of 15Cr stainless steel in Oxidant), intensity is improved.Therefore, in order to obtain at quenching state taking martensite as main tissue, avoid the appearance of ferritic structure, than the Composition Design of 13Cr and super 13Cr, take the measure (maximum level is no more than 7.5 wt %) of suitable raising Cr equivalent (maximum level is no more than 15.5 wt %) and Ni equivalent, because Cr and ferrite stabilizer content are higher, martensite transformation temperature is lower, so that under conventional quenching processing condition, can not obtain martensitic stucture (high Cr content can make martensite transformation temperature drop to room temperature and sub-zero zero), and the appearance of amount of ferrite tissue can cause the strength of materials significantly to decline.Main alloy element Cr in the present invention, the quenching state tissue that Ni content can be guaranteed high-strength 15Cr in Fig. 1 shown in region.Although due to the raising (while exceeding 15%) of Cr content, in matrix, inevitably there is austenite phase, but its content is no more than 5%, and, austenite appears between martensite bar bundle and (sees Fig. 2 with sheet, austenite structure is body-centered cubic, moulding, toughness is better), be of value to the toughness that improves material.
3), than general martensite stainless steel material, the alloying element W that is no more than 0.7 wt % and the Alloy Elements Mo that is no more than 2.4wt% in the present invention, have been added.The carbide formability of W is stronger, the same with Mo, and the carbide of formation hinders softening in the time of tempering, and W can also improve the hot strength of 15Cr, and its strength retrogression's degree under the hot conditions of 200 DEG C is weakened; And being added with to benefit and improving its pitting corrosion resistant performance in the acid solution of reductibility and alkaline medium of Mo element.But too high W and Mo content will cause the unstable (promoting the formation of ferritic phase) of its crystalline structure;
4) interpolation of Cu element also has certain help to improving the anti-uniform corrosion ability of 15Cr stainless steel in non-oxidizable corrosive environment, at high Cl
-in corrosive environment, the synergy of Cu and Mo element will improve 15Cr stainless steel resistance to corrosion in reductant;
5) adding of the carbide such as Ti, Nb, V, be conducive to form the carbide particle that disperse distributes, suppressing the carbide of Cr separates out at crystal boundary, play precipitation strength effect, form highdensity dislocation knot simultaneously, dislocation is played to pinning effect, reduced the stainless SCC of high-strength 15Cr or SCC susceptibility.
According to Composition Design scheme of the present invention, prepare through vacuum induction furnace (VIM) melting → die casting → forging → hot rolling → thermal treatment the high-strength 15Cr stainless steel materials that thickness is 10mm.The microstructure of high-strength 15Cr Martensite Stainless Steel oil pipe material is tempered martensite's (see figure 3); Table 1～table 3 is the test result of its intensity, hardness and impact property, and tensile strength, hardness and the impelling strength of the high-strength 15Cr of the present invention all meets the performance requriements of listed grade of steel material in relevant emblem mark.
Compared with prior art, advantage of the present invention is as follows: minimum yield strength can reach 925MPa(125ksi grade of steel), critical use temperature is 210 DEG C, CO
2more than dividing potential drop can reach 10MPa, Cl

The present invention can meet bottom temperature higher than 175 DEG C, bottomhole wellbore pressure higher than 100MPa, CO
2dividing potential drop is greater than 5MPa, Cl
-concentration is greater than 100000mg/L and contains micro-H
