Tig rau ntawm Drilling Rig hloov cov kua dej rau hauv txoj hlua khawb
Lub Drilling Swivel yog cov khoom siv tseem ceeb rau kev sib hloov ntawm cov haujlwm hauv av. Nws yog qhov kev sib txuas ntawm lub kaw lus hoisting thiab lub cuab yeej drilling, thiab qhov kev sib txuas ntawm lub kaw lus ncig thiab lub kaw lus tig. Sab saud ntawm Swivel yog dai rau ntawm lub hookblock los ntawm qhov txuas elevator, thiab txuas nrog lub raj gooseneck rau lub raj drilling. Sab qis yog txuas nrog lub raj drilling thiab lub cuab yeej downhole drilling, thiab tag nrho tuaj yeem khiav mus rau saum thiab nqis nrog lub thaiv kev mus ncig.
Ua ntej, qhov yuav tsum tau ua ntawm kev khawb cov kais dej rau kev ua haujlwm hauv av
1. Lub luag haujlwm ntawm kev khawb cov kais dej
(1) Cov cuab yeej tho qhov kom raug kom tiv taus qhov hnyav tag nrho ntawm cov cuab yeej tho qhov downhole.
(2) Xyuas kom tseeb tias lub laum qis dua yog dawb tig thiab qhov sib koom ua ke sab saud ntawm kelly tsis buckle.
(3) Txuas nrog lub qhov dej drilling kom twj cov kua siab siab rau hauv cov yeeb nkab laum tig kom paub txog kev drilling ncig.
Nws tuaj yeem pom tias lub qhov dej drilling tuaj yeem paub txog peb lub luag haujlwm ntawm kev tsa, kev tig thiab kev ncig, thiab yog ib qho tseem ceeb ntawm kev tig.
2. Cov kev cai rau kev khawb cov kais dej hauv kev ua haujlwm downhole
(1) Cov khoom tseem ceeb ntawm cov kais dej drilling, xws li lub nplhaib nqa, lub yeeb nkab nruab nrab, lub nra hnyav, thiab lwm yam, yuav tsum muaj lub zog txaus.
(2) Lub kaw lus sib dhos ua ke yuav tsum muaj lub zog siab, hnav-resistant thiab corrosion-resistant, thiab nws yooj yim los hloov cov khoom puas tsuaj.
(3) Lub kaw lus roj qis-siab yuav tsum tau kaw zoo, tiv taus corrosion thiab muaj lub neej ua haujlwm ntev.
(4) Cov duab thiab cov qauv ntawm lub qhov dej drilling yuav tsum du thiab angular, thiab lub kaum sab xis ntawm lub nplhaib nqa yuav tsum yooj yim rau dai hooks.
Cov Nta Kev Txawj:
• Nrog ob lub pin alloy steel sub xaiv tau.
• Cov kav dej ntxuav thiab cov khoom ntim khoom yog cov qauv sib xyaw ua ke thiab yooj yim hloov.
• Lub gooseneck thiab lub raj xa dej rotary txuas nrog los ntawm kev sib koom ua ke lossis API 4LP.
