Abstract
A casing resisting CO2 corrosion for oil well or gas well is made up of stainless pipe, which contains C (0.08-0.25), Si (0-1), Mn (0.6-1.2), P (0-0.3), S (0-0.020), Ni (0-1), Cr (8.0-25) Cu (0-0.25) and Fe (rest), through smelting steel, host rollling of seamless pipe, quenching and annealing. Its advantages are high strength, toughness, and hardness, and high resistance to CO2 corrosion.
Description
The invention belongs to the anti-corrosion petroleum sleeve pipe, particularly a kind of sleeved petroleum pipe resisting CO 2 corrosion and production method.
Present enhancing along with environmental consciousness, human demand to clear energy sources is more and more, natural gas is exactly a kind of underground clear energy sources that extensively is present in, people tap natural gas in drilling well always for a long time, adopt petroleum casing pipe in exploitation and transport gas, but owing to contain a large amount of CO in many natural gases
2And contain water, this wet CO
2Gas has strong corrosiveness to ordinary casing.
The purpose of this invention is to provide a kind of sleeved petroleum pipe resisting CO 2 corrosion and production method, the common petroleum sleeve pipe that overcomes prior art can be by wet CO
2Gas strong corrosion shortcoming and defect.Contain wet CO to satisfy exploitation
2The needs of the oil and natural gas of gas.
The object of the present invention is achieved like this: sleeved petroleum pipe resisting CO 2 corrosion is to select for use the martensitic stain less steel of low-phosphorous P, sulphur S content as pipe material, and steel grades (weight %) is designed to: C=0.08～0.25 Si≤1.00 Mn=0.6～1.2 P≤0.030 S≤0.020 Ni≤1.0 Cr=8.0～25.0 Cu≤0.25 surplus is the petroleum casing pipe of Fe.Its yield strength scope is: 552～758Mpa, tensile strength 〉=665Mpa, hardness HRC≤28.
The production method of sleeved petroleum pipe resisting CO 2 corrosion is: adopt the high-quality steel scrap to add sponge iron as steelmaking feed, add method of refining steel-making with electric arc furnaces, adding after the refining directly with electric arc furnaces, continuous casting forges into circular pipe blank after becoming circular pipe blank or casting, again circular pipe blank is heated in annular furnace, preheating section temperature: 800 ℃, bringing-up section temperature: 1200～1300 ℃, soaking zone temperature: 1300～1400 ℃, tapping temperature: 1200～1280 ℃, do not allow to stay stove, after the heat centering, use the punch perforation of two roller Man band godets, hollow billet inner surface after the perforation is handled with borax, is rolled into hollow forging through φ 250mm retained mandrel tandem mill again, and hollow forging can directly carry out sizing by sizing or after heating again; Steel pipe after the hot rolling uses reheating furnace to carry out slow cooling, and cooled steel pipe is through sawing, aligning and flaw detection; Its heat treating regime is: 1000～1100 ℃ of+650～750 ℃ of tempering of quenching.
Advantage of the present invention is:
This sleeved petroleum pipe resisting CO 2 corrosion carbon dioxide corrosion-resistant performance is strong, production method easy operating, good process repeatability.Be fit to contain wet CO
2The oil well of gas or the use of gas well.
Sleeved petroleum pipe resisting CO 2 corrosion be a kind of martensitic stain less steel of selecting low-phosphorous P, sulphur S content for use as pipe material, steel grades (weight %) is designed to: C=0.08～0.25 Si≤1.00Mn=0.6～1.2 P≤0.030 S≤0.020 Ni≤1.0 Cr=8.0～25.0 Cu≤0.25 surplus is the petroleum casing pipe of Fe.Carry out service check by API SPEC.5CT (98 editions), its yield strength scope is: 552～758Mpa, tensile strength 〉=665Mpa, hardness HRC≤28.
The production method of sleeved petroleum pipe resisting CO 2 corrosion is: adopt the high-quality steel scrap to add sponge iron as steelmaking feed, adding after the refining directly with electric arc furnaces, continuous casting forges into round base after becoming circle base or casting, through annular furnace heating (preheating section temperature: 800 ℃, bringing-up section temperature: 1200～1300 ℃, soaking zone temperature: 1300～1400 ℃, tapping temperature: 1200～1280 ℃, do not allow to stay stove), after the heat centering, use the punch perforation of two roller Man band godets, when perforation, adopt best punching rate, to reduce in temperature rise prevents, the generation of external defects, and in roll spacing, lead, best of breed is carried out in aspects such as top head front-extending quantity, to guarantee the production direct motion, effectively reduces tool wear.Hollow billet inner surface after the perforation is handled with borax, be rolled into hollow forging through φ 250mm retained mandrel tandem mill again, do not need temperature-compensating, milling train inlet temperature, mill speed, deflection distribution are optimized, guaranteeing sufficiently high outlet temperature, and directly by sizing or carry out sizing after the heating again.Steel pipe after heat is pricked uses reheating furnace to carry out slow cooling, and cooled steel pipe is through sawing, aligning and flaw detection.Again by following heat treating regime heat treatment: 1000～1100 ℃ of+650～750 ℃ of tempering of quenching are to guarantee the performance of sleeve pipe: carry out service check by API SPEC.5CT (98 editions), its yield strength scope is: 552～758Mpa, tensile strength 〉=665Mpa, hardness (HRC)≤28, other performances are pressed API SPEC.5CT (98 editions) correlation formula and are calculated.
