Lo lus "crossover sub" yog siv los piav qhia txog cov khoom siv kho tshuab nrog cov xov sib txuas. Nws yog siv los txuas cov khoom sib txawv nrog ntau qhov sib txawv los yog xov hom.
Crossover subs feem ntau pom nyob rau hauv lub laum yeeb nkab ntawm lub laum yeeb nkab thiab laum dab tshos, nrog rau lwm qhov chaw thoob plaws hauv lub laum txoj hlua. Cov khoom no cia lub driller hloov kev teeb tsa raws li lawv qhov chaw nyob.
Crossover subs feem ntau muab kev sib txuas ntawm cov kav dej thiab cov dab tshos. Lawv tau tsim nrog lub thawv thiab cov xov.
Thaum ob threaded Cheebtsam tau koom nrog, ib kawg ntawm crossover sub yog tsim kom phim cov xov qauv ntawm ib tug ntawm cov Cheebtsam yuav tsum tau koom, thiab lwm kawg yog tsim kom phim cov xov qauv ntawm lub thib ob tivthaiv. Laum rigs feem ntau suav nrog ntau yam ntawm crossover subs thiab cov neeg ua haujlwm siv lawv raws li xav tau los koom nrog qhov sib txawv.
Subs 'threaded kev sib txuas yog tiv thaiv los ntawm ib txheej ntawm phosphate-coated cov ntaub ntawv uas tiv thaiv galling thaum lub sij hawm thawj make-up. Subs yog tsim raws li cov lus qhia tshwj xeeb uas tau muab los ntawm American Petroleum Institute API.
Crossover subs yog ib feem tseem ceeb ntawm kev ua haujlwm drilling
Crossover subs yog ib qho tseem ceeb ntawm txhua qhov kev ua haujlwm drilling raws li lawv muab qhov yooj yim los hloov txoj hlua tho rau qhov tshwj xeeb ntawm kev ua haujlwm zoo. Lawv kuj tau siv los kho qhov puas ntawm cov hlua laum thiab txuas qhov sib txawv ntawm cov hlua tho. Crossover subs ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua tiav ntawm kev ua haujlwm drilling.
Crossover subs feem ntau yog cov cuab yeej xav tau rau cov roj rig laum hlua
Raws li qhov xav tau ntawm cov neeg siv khoom lossis cov haujlwm tshwj xeeb hauv nqe lus nug, ntau lub tuam txhab muab lossis tsim cov crossover circulating subs. Subs yog nruab nrog ib sab chaw nres nkoj los yog ib qho chaw nres nkoj inline los pab hauv cov dej ntws. Feem ntau ntawm cov kev sib txuas raug txiav kom ua tau raws li kev nyab xeeb thiab kev xav tau hauv av. Lawv tau ua los ntawm cov hlau kub-kho kom muaj zog dua thiab kav ntev.
Crossover Subs feem ntau yog siv rau ntau lub hom phiaj
Crossover subs yog siv los hloov los ntawm ib qho kev sib txuas mus rau lwm qhov. Cov khoom siv no kuj tseem siv tau los txuas ntxiv lub neej ntawm cov khoom siv laum kim dua. Crossover subs muaj nyob rau hauv peb hom sib txawv. Hauv hom kev teeb tsa hauv qab no, kev sib txuas ntawm cov subs muaj nyob rau hauv peb qhov kev hloov pauv:
Vigor Drilling muab cov X-Over Pin (Txiv neej) x Box (poj niam), Pin (txiv neej) x Pin (Txiv neej), thiab Box (poj niam) x Box (poj niam) rau Drilling hlua crossover sub.
Vigor's Crossover Sub (X-Over) yog siv rau kev hla dhau los ntawm qhov loj ntawm ib qho kev sib txuas mus rau lwm qhov. Kuj tseem siv tau rau kev ncua lub neej kev sib txuas ntawm cov khoom siv kim dua drilling.
Crossover Thiab Subs yog tsim los ntawm 4145H. Cov kev sib txuas yog tiv thaiv los ntawm phosphate nto txheej uas txo cov galling thaum thawj zaug ua-up tshwm sim. Sub yog tsim raws li API 7-1 Specification.Vigor tuaj yeem muab ntau qhov ntau thiab tsawg ntawm kev thov.Yog tias koj txaus siab rau Vigor's Crossover Sub, thov tsis txhob yig tiv tauj peb kom tau txais cov khoom zoo tshaj plaws thiab cov khoom zoo tshaj plaws. kev txhawb nqa.
