Description
Technical field
The present invention relates to tubing and casing, be specifically related to a kind of anti-H 2 S stress corrosion rimose tubing and casing and method of manufacture thereof, that under hydrogen-sulfide environmental, uses has a good resistance H 2 S stress corrosion.
Background technology
Oil production much contains corrosive mediums such as hydrogen sulfide with the employed environment of tubing and casing; Not only can carry out uniform corrosion to the body surface, can also generate hydrogen with the iron and steel effect, it is inner to get into steel substrate; Make sleeve pipe generation stress corrosion fracture; In the extremely short time, lost efficacy, thereby brought great financial loss and potential safety hazard to oil field production, annual because of CO
2And H
2The accident that the S corrosion is produced brings financial loss up to more than hundred million yuan to the oil field.
The seamless tubing and casing technical process of producing hydrogen sulfide corrosion resistant is: pipe is smelted, is cast into to steel grade, rolling for carrying out the modified thermal treatment of homogeneous tube behind the seamless tube, processes the tubing and casing of anti-H 2 S stress corrosion at last through mechanical workout.
The tubing and casing that hydrogen sulfide corrosion resistant tubing and casing and general oil production are used is difference to some extent on selection and production technique, mainly is steel grade design and thermal treatment process.
In the steel grade design; Generally be to add the alloying element that improves hardening capacity and temper resistance; In the hope of in quenching process, obtaining more martensitic stucture and higher hardness; Guarantee the homogeneity of tissue,, simultaneously impurity elements such as P, S, O are carried out strictness control such as C, Mn, Cr, Mo, V etc.The main high temperature quenching-and-tempering process that adopts obtains average tempering sorbite tissue on thermal treatment process, and the tempered sorbite tissue has best anti-H 2 S stress corrosion performance in the various tissues of low alloy steel.
Like Chinese patent CN00136666.1, CN200510029218.0; CN200580019466.5 etc.; All adopt the steel grade of one or more alloying elements such as adding Cr, Mo, V, Ni, Cu, Nb and heat-treat the tubing and casing of producing anti-H 2 S stress corrosion; But along with alloying element price in recent years skyrockets, more and more stronger for the tubing and casing demand of anti-H 2 S stress corrosion cheaply, existing at present tubing and casing can not satisfy the requirement of user to product up-gradation.
Chemical ingredients, the product grade of steel of the existing hydrogen sulfide corrosion resistant oil bushing steel of table 1
Summary of the invention
The objective of the invention is to design a kind of anti-H 2 S stress corrosion rimose tubing and casing and method of manufacture thereof; It is a kind of 80ksi steel grade sulfur resistant hydrogen-type corrosion tubing and casing of carbon manganese steel composition system; Performance index: press the API5CT standard; Rt0.5 (ys): 552-655MPa; Tensile strength: greater than 655MPa, unit elongation: greater than 15%, the hydrogen sulfide corrosion resistance ability: sulfur resistance adopts A method sample under the load that loads nominal ys more than 85% not ftracture through 720 hours according to the NACE0177-2005 standard; Have low-cost and good anti-H 2 S stress corrosion cracking performance, satisfy the needs of oilfield prospecting developing with anti-H 2 S stress corrosion requirement.
For reaching above-mentioned density, technical scheme of the present invention is:
The present invention adopts carbon manganese steel composition system and adds a small amount of B, does not add alloying elements such as Cr, Mo, Ni, V, Ni, Cu, controls the tubing and casing of lower inclusion content and anti-ization of the thermal treatment process production hydrogen stress corrosion of adopting high temperature, short time.In the composition design, optimize the content of C, Mn and do not add the higher alloying element of price, have advantage cheaply; Add B, utilize its strengthening effect, the crystal boundary free energy is reduced, hinder the formation of the hydrogenate that makes embrittlement of grain boundaries crystal boundary; The effect that utilize to improve hardening capacity has remedied the insufficient problem of hardening capacity of not adding alloying element and being brought, the content of the back martensitic stucture that guaranteed to quench; Because composition system of the present invention is a carbon manganese steel, does not add alloying elements such as Cr, Mo, anti-temper resistance is relatively poor; If adopt about two hours tempering heat treatment process of the anti-sulphur pipe of general alloy, mechanical property can not reach standard-required, and carbide particle can be thicker; Be unfavorable for anti-ization hydrogen stress corrosion performance, therefore adopt the prompt tempering thermal treatment process of high temperature, short time, the tempering heat treatment temperature of more general anti-sulphur pipe improves 10-20 ℃; Tempering time shortens over half; Guarantee to obtain tiny equally distributed carbide and change sufficient tempered sorbite tissue, improved anti-ization hydrogen stress corrosion performance, satisfy mechanical property requirements simultaneously; And can improve production efficiency greatly owing to shortened heat treatment time, reduce production cost.
Particularly; Anti-H 2 S stress corrosion rimose tubing and casing of the present invention; Its composition quality per-cent is: C:0.2 ~ 0.3%, Si:0.1 ~ 0.5%, Mn:0.3 ~ 0.6%, P≤0.012%, S≤0.002%, Ti:0.01 ~ 0.05%, Al:0.01 ~ 0.08%, Ca:0.0005 ~ 0.005%, B:0.001 ~ 0.003%, all the other are Fe and unavoidable impurities.
In composition design of the present invention:
C:0.2 ~ 0.3%, C are carbide forming element, can improve the intensity of steel, and DeGrain when too low can the remarkable anti-ization hydrogen stress corrosion performance that reduces steel when too high.
To improve the ys of steel, unsuitable too high, too high meeting worsens processing and toughness, is lower than 0.1% DeGrain in ferritic for Si:0.1 ~ 0.5%, Si solid solution.
Mn:0.3 ~ 0.6%, Mn are austenite former, can improve the hardening capacity of steel, and content is not obvious less than effect in 0.3 o'clock, and content with the microstructure segregation that significantly increases in the steel, influenced the homogeneity and the anti-ization hydrogen stress corrosion performance of hot rolling microstructure greater than 0.6% o'clock.
Ti:0.01 ~ 0.05%, Ti are strong carbonitride forming elements, remarkable refine austenite crystal grain, owing to added B, Ti can form TiN with N, and can prevent to form BN and the effect that influences B,, if content is too high, be prone to form thick TiN, reduce material property.
B:0.001 ~ 0.003; B can increase hardening capacity, can effectively strengthen crystal boundary, makes along the precipitate of crystal boundary to reduce; Can postpone the crackle forming process on the crystal boundary; Improve resisting sulfide stress corrosion crack performance, content is not obvious less than effect in 0.001% o'clock, and the too high then steel-making of content is difficult to accurate control.
Al:0.01 ~ 0.08%, Al have played the effect of desoxydatoin and crystal grain thinning in steel, also improved the stability and the solidity to corrosion of superficial film in addition.When add-on is lower than 0.01%, DeGrain, add-on surpasses 0.08%, the mechanical property variation.
Ca:0.0005 ~ 0.005%, Ca plays the effect of deoxidization desulfuration at steel grade, makes impurity S and Ca form the CaS of nodularization, prevents that S and Mn from generating the MnS of anti-H 2 S stress corrosion poor-performing, and add-on is above 0.005%, and the steel grade oxide impurity increases.
P: S≤0.012% :≤0.002%, P and S are the detrimental impurity elements in the steel, too high levels can worsen the toughness of resisting sulfide stress corrosion performance and steel, therefore should reduce phosphorus, the sulphur content in the steel as far as possible.
The method of manufacture of anti-H 2 S stress corrosion rimose tubing and casing of the present invention comprises the steps:
1) smelts, casts
