Raw Material Xaiv:
Kev xaiv cov khoom nyoos yog ib kauj ruam yooj yim mus rau qhovtus menyuam devsib koommanufacturing txheej txheem rau downhole drilling. Cov qib steel zoo nrog cov cuab yeej siv tau zoo thiab cov khoom tsim hluav taws xob tau txiav txim siab kom ua tau raws li qhov xav tau ua ntej ntawm qhov chaw drilling.
Alloy steels: High-strength, low-alloy (HSLA) steels muaj qhov sib npaug ntawm lub zog, toughness, thiab weldability, ua rau lawv haum rau ntau yam drilling.
Stainless hlau: Corrosion-resistant stainless hlau, xws li austenitic lossis martensitic qib, yog siv nyob rau hauv ib puag ncig uas muaj peev xwm corrosion siab los yog hnyav kev pab cuam.
Nickel-raws li alloys: Cov nickel alloys uas muaj zog corrosion-resistant, xws li Inconel lossis Hastelloy, yog qhov nyiam rau qhov chaw huab cua uas muaj qhov kub thiab txias, siab, thiab corrosive gases.
Forging thiab Forging:
Tom qab xaiv cov qib steel kom zoo, cov khoom siv ntuj tsim los ntawm kev tsim thiab framing cycles ua kom zoo tagnrho cov duab thiab cov yam ntxwv ntawm kev sib koom ua ke. Cov voj voog no suav nrog kev ua kom sov cov hlau kom kub siab, taug qab los ntawm kev tswj kev sib tw los ntawm cov txheej txheem, piv txwv li, qhib ncaws lub thoob fashioning, kaw tom cov plua plav tsim, lossis yob framing.
Thaum lub sij hawm fashioning, warmed steel yog raug rau compressive powers, uas reshape cov khoom rau hauv zoo tagnrho cov duab. Qhov kev sib cuam tshuam no hloov kho cov khoom siv hluav taws xob ntawm cov hlau los ntawm kev ua kom zoo dua cov qauv nplej thiab ntxiv kev txhim kho lub zog thiab ruaj khov.
Kev kho cua sov:
Kev kho cua sov plays lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom siv kho tshuab thiab kav ntevpup sib. Ntau yam txheej txheem kho cua sov yog ua haujlwm, nyob ntawm qib steel thiab cov yam ntxwv ua tau zoo.
Cov txheej txheem kev kho cua sov:
quenching thiab tempering: Cov txheej txheem no yuav tsum tau ua kom txias (quenching) cov hlau los ntawm qhov kub thiab txias kom ua tiav ib qho nyuaj martensitic microstructure, ua raws li kev tswj xyuas reheating (tempering) kom toughness thiab txo cov kev ntxhov siab sab hauv.
Normalization: Normalization muaj cua sov cov hlau saum toj no qhov tseem ceeb kub thiab tom qab ntawd cua-txias, uas ua rau ib tug ntau yam microstructure thiab txhim kho mechanical zog.
Annealing: Annealing muaj cua sov thiab tswj cov cua txias ntawm cov hlau los txo cov kev ntxhov siab sab hauv, txhim kho machinability, thiab txhim kho ductility.
Machining thiab Finishing:
Tom qab forging thiab kev kho cua sov,pup pob qij txha rau downhole drillingundergo ntau yam machining thiab tiav cov txheej txheem kom ua tiav qhov ntev, qhov chaw tiav, thiab kev kam rau siab xav tau rau kev siv downhole.
Common machining txheej txheem:
Tig: Tig yog siv los tsim cov duab cylindrical thiab cov kab uas hla ntawm qhov sib koom ua ke, kom ntseeg tau tias muaj qhov sib luag thiab concentric nto.
Milling: Kev ua haujlwm milling yog siv los tsim cov yam ntxwv tshwj xeeb, xws li grooves, flats, lossis slots, ntawm qhov sib koom ua ke.
Kev Sib Tsoo: Sib tsoo yog siv los ua kom muaj kev sib haum xeeb thiab ua kom zoo nkauj, tshwj xeeb tshaj yog rau cov chaw tseem ceeb xws li cov xov sib txuas lossis cov khoom sib khi.
Xov xov:
Threaded kev sib txuas yog qhov tseem ceeb raupup sib, tso cai rau lawv kom ruaj ntseg txuas nrog rau lwm yam downhole Cheebtsam. Ntau cov txheej txheem threading yog ua haujlwm los tsim kom muaj kev sib raug zoo, ruaj threaded kev sib txuas.
Kev kho deg:
Cov txheej txheem kho deg feem ntau yog siv rau cov pob qij txha txhawm rau txhim kho lawv cov kev ua tau zoo thiab ua haujlwm ntev hauv kev xav tau ntawm qhov chaw ib puag ncig.
Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb:
Kev tswj xyuas zoo thiab cov txheej txheem tshuaj xyuas yog ib qho tseem ceeb rau kev tsim khoom ntawmpup pob qij txha rau downhole drillingkom ua tau raws li cov qauv kev lag luam thiab cov neeg siv khoom tshwj xeeb.
Nondestructive testing (NDT): NDT txoj kev, xws li kev ntsuam xyuas ultrasonic, kev soj ntsuam cov khoom sib nqus, los yog kev ntsuam xyuas cov tshuaj dye penetrant, yog siv los xyuas qhov tsis xws luag sab hauv thiab saum npoo yam tsis muaj kev puas tsuaj rau cov khoom.
Kev tshuaj xyuas qhov ntev: Kev ntsuas qhov ntev yog ua los ntawm kev siv lub tshuab ntsuas kev sib koom tes (CMMs) lossis lwm yam khoom siv ntsuas ntsuas los txheeb xyuas qhov ua tau raws li qhov kev cia siab thiab cov duab geometry.
Kev ntsuas kev ua tau zoo: Kev ntsuas kev ua tau zoo, xws li kev ntsuas siab, ntsuas kev qaug zog, lossis kev kuaj corrosion, yog ua los ntsuas qhov ntsuas.pup sib's muaj peev xwm tiv taus qhov kev cia siab downhole tej yam kev mob thiab ua kom ntseeg tau kev ua haujlwm.
Kev ntsuam xyuas cov khoom siv: Kev tshuaj ntsuam xyuas cov khoom siv tshuaj lom neeg thiab cov khoom siv kho tshuab, xws li tensile, cuam tshuam, thiab hardness tests, yog ua los xyuas cov khoom ua raws li cov kev cai.
