Raws li tus kws tshaj lij hauv kev lag luam roj thiab roj, kev nkag siabAPI laum yeeb nkabspecifications yog ib qho tseem ceeb rau kev ua kom muaj kev nyab xeeb, kev cia siab, thiab kev ua haujlwm ntawm kev ua haujlwm drilling. Hauv tsab xov xwm no, peb yuav txheeb xyuas qhov tshwj xeeb ntawm cov khoom siv qib, cov khoom siv kho tshuab, thiab hom kev sib txuas raws li tau teev tseg los ntawm American Petroleum Institute (API) cov qauv.
① Cov khoom siv thiab cov qauv tsim khoom
Kev tsim kho ntawm cov kav dej laum yog txheej txheem txheej txheem uas yuav tsum tau ua raws li cov khoom siv nruj thiab cov qauv tsim.
Qib ntawm Steel:API laum yeeb nkabs yog tsim los siv ntau qib ntawm cov hlau, txhua tus xaiv rau nws cov cuab yeej tshwj xeeb thiab cov ntawv thov. Piv txwv li, qib xws li H-40, J-55, K-55, N-80, thiab P-110 raug xaiv raws li qhov dej qhov tob, siab , thiab kub tej yam kev mob.
Cov txheej txheem tsim khoom: Cov txheej txheem tsim khoom rau cov kav dej laum suav nrog kev ua kom zoo tshaj plaws ua raws li kev kho cua sov zoo. Cov txheej txheem no ua kom cov kav dej laum tuaj yeem tiv taus cov xwm txheej hnyav uas tau ntsib thaum lub sijhawm drilling. Cov txheej txheem forging txhim kho cov yeeb nkab cov dej ntws, uas yog qhov tseem ceeb rau nws txoj kev ncaj ncees. Kev kho cua sov, ntawm qhov tod tes, kho cov khoom siv ntawm cov hlau, muab qhov tsim nyog hardness thiab tensile lub zog.
② Mechanical Properties thiab Tolerances
Mechanical Properties ntawm ibAPI laum yeeb nkabNws yog ib qho tseem ceeb rau nws cov kev ua tau zoo raws li qhov xav tau ntawm drilling.
Tensile Strength: Qhov tsawg kawg nkaus tensile lub zog yuav tsum tau rau txhua qib ntawm laum yeeb nkab yog teev los xyuas kom meej tias cov yeeb nkab muaj peev xwm lis lub axial loads thaum lub sij hawm drilling tsis tawg. Lub zog tensile yog qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus thaum raug ncab ua ntej tsis ua hauj lwm, uas yog qhov tseem ceeb rau kev tiv thaiv lub siab rub thiab lub zog torque.
Yield Point: Qhov no yog theem kev ntxhov siab ntawm cov hlau hloov ntawm elastic mus rau yas deformation. Qhov taw tes tawm los yog qhov tseem ceeb vim nws qhia tias qhov pib ntawm qhov deformation mus tas li hauv cov khoom siv yeeb nkab. API cov lus qhia tshwj xeeb rau qhov taw tes tawm los xyuas kom meej tias cov kav dej tho tuaj yeem deform elastically nyob rau hauv kev ntxhov siab yam tsis muaj kev puas tsuaj mus tas li, tswj xyuas lawv cov qauv kev ncaj ncees.
③ Hom xov thiab kev sib txuas
Cov xov thiab kev sib txuas hom ntawm ibAPI laum yeeb nkabyog tsim los muab kev ruaj ntseg thiab txhim khu kev qha nyob rau hauv txoj hlua xyaum.
API Xov: Muaj ntau ntau hom API threads, xws li API Regulative Thread (ART) thiab API Buttress Thread, txhua qhov tshwj xeeb qhov ntev thiab kam rau ua. Cov xov no yog tsim los muab kev sib txuas zoo ib yam thiab ruaj ntseg ntawm cov tho yeeb nkab.
Kev sib txuas lus sib txuas: Cov kev sib txuas sib txuas ntawm cov kav dej tho yog tsim los rau kev sib raug zoo hauv cov hlua tho kev sib dhos. Kev tsim ntawm cov kev sib txuas no ua kom ntseeg tau tias cov kav dej laum tuaj yeem koom tau yooj yim thiab txiav tawm, ua kom yooj yim rau kev ua haujlwm rig. Cov kev sib tshuam kuj suav nrog cov yam ntxwv los tiv thaiv kev hla txoj xov thiab muab lub foob tiv thaiv cov dej xau.
API laum yeeb nkabcov lus qhia tshwj xeeb yog cov txheej txheem dav dav uas ua kom zoo, kev nyab xeeb, thiab kev ua haujlwm ntawm cov kav dej tho siv hauv kev lag luam roj thiab roj. Los ntawm kev ua raws li cov lus qhia tshwj xeeb no, cov tuam txhab drilling tuaj yeem ua haujlwm nrog kev ntseeg siab, paub tias lawv cov cuab yeej ua tau raws li cov qauv kev lag luam siab tshaj plaws.
