Cov qauv hluav taws xob tseem ceeb ntawm tho yeeb nkab
Raws li ib tug tseem ceeb tivthaiv hauv kev ua haujlwm drilling, cov qauv tsim ntawm tho kav hlau ncaj qha cuam tshuam drilling efficiency, kev nyab xeeb, thiab kev pabcuam lub neej. Hauv qab no yog cov lus qhia ntxaws ntxaws ntawm cov qauv tseem ceeb thiab lawv cov haujlwm:
I. Cov txheej txheem tseem ceeb
Tho kav hlau feem ntau muaj ob qhov chaw loj: tusYeeb Nkab Lub CevThiab tusCuab Yeej Siv.
Yeeb Nkab Lub Cev (Lub Cev)
Khoom: Seamless alloy steel kav (piv txwv li, api - txheem qib kawm e75, X 905, S135, S135, S135, S135, S135).
Yam ua hauj lwm:
Torque kis: Xa cov zog sib hloov los ntawm cov kav hlau laum kom tsav lub laum me me rau pob zeb tawg.
Drilling Flue Conveyance: Hollow sab hauv comia channel charg kom txias me ntsis thiab nqa cuttings rov qab mus rau saum npoo.
Load cov kabmob: respressions nro, compression, khoov, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co, thiab kev co.
Tsim nta:
Phab ntsa tuab: Feem ntau 9-11 hli; Thicker rau cov hmoov sib sib zog nqus dej lossis siab- siab tsim.
Ntev: Tus Qauv Ntev ntawm 27-30 ft (8.23-9.14 m) lossis 38-45 ft (11.58-13.72 m).
Kev kho deg: tooj plating, siab - zaus} zaus quenching, thiab lwm yam, kom txhim kho kev hnav thiab corrosion tsis kam.
Cuab Yeej Siv
Rooj mov: Txuas cov kav kav hlau ib sab thiab cov transmits torque / axial loads.
Lub tsev:
Tus pin (txiv neej): xov threadly sab nraud kawg tau tso rau hauv lub thawv.
Box (Poj Niam): Sab Hauv Sab Hauv Kawg Txais Tus PIN.
Tsim nta:
Upsetting: Cov phab ntsa sib koom ua kom tuab dua cov yeeb nkab lub cev (sab hauv, sab nraud, lossis ob qho tib si) rau lub zog.
Xov Hom:
Sab hauv flush (yog): uniform inner / sab nraud diameters; Kev ywj ntws tsis kam rau cov dej ntiav.
Tag nrho lub qhov (fh): cov uas hla me me ntawm cov taub nyob sab hauv; Nruab nrab ntws tsis kam.
Tsis tu ncua (REG): Qhov ntau ntawm cov uas hla nrog tuab sab hauv phab ntsa; Siab zog tab sis ntau dua ntws tawm tsam.
Numbered sib txuas (NC): ntxhib {{i}} xov txheem qauv (piv txwv li, NC50) rau qhov siab siab.
Ii. Ntu Cov Qauv
Hnav band
Qhov chaw: sab nraud ntawm qhov sib koom ua ke.
Muaj nuj nqi: txo kev txhuam tawm tsam cov kab ke / tej teeb meem, nce kev sib koom tes kav.
Cov khoom siv: nyuaj alloy lossis tungsten carbide txheej.
Cov Tshuab Sealing
Hlau - rau - Cov Ntsaws Ruaj Ruaj: ntawm threaded sib txuas los tiv thaiv av xau.
Roj Hmab O {- rings: ntxiv ntawm cov hauv paus cag rau kev sib khi sib khi.
Cim & Txheej Txheem
Cim Cim: Sau nrog qib hlau, cov lus qhia tshwj xeeb, thiab cov ntsiab lus.
Txheej txheem: anti {- corrosion (piv txwv li, epoxy) lossis hnav} tiv taus (piv txwv li, Nickel Alloy).
III. Cov Qauv Tsim Qauv
Qeeb zog tsis kam
Lub vojvoog hloov pauv: Cov kab txiav loj ntawm lub cev -} Kev sib txuas lus los txo kev ntxhov siab.
Kev kho cua sov: quenching thiab tempering kom txhim kho kev qaug zog ua tau zoo.
Corrosion Kuj
Cov Khoom Siv Khoom Siv: Chromium / Molybdenum / Nickel alloys rau h₂s tsis kam.
Kev kho cov npoo: zinc / chrome plating lossis anti - corrosion txheej.
Lub Hnav Txom Nyem
Siab - muaj zog hlau: thinner phab ntsa yam tsis muaj lub zog txeem.
Hollow pob qij txha: qhov hnyav txo ntawm hollow sib koom ua ke tsim.
