Lub tshuab nqus dej twj tso kua mis yog cov cuab yeej tseem ceeb hauv dej hiav txwv uas txuas rau lub qhov dej hauv qab dej hiav txwv thiab lub tshuab hluav taws xob (BOP) mus rau qhov chaw drilling los yog chav tsev. Tsis zoo li cov yeeb nkab conductor, uas yog lub hauv paus ruaj khov, qhov drilling riser ua haujlwm raws li cov kav dej ib ntus uas muaj lub siab thaum lub sijhawm ua haujlwm drilling. Nws lub luag haujlwm tseem ceeb yog muab txoj hauv kev txuas mus ntxiv rau cov kua dej drilling, txiav thiab tswj lub siab ntawm lub seabed thiab lub platform.
Drilling risers yog qhov tseem ceeb rau kev tshawb nrhiav dej tob thiab ultra-deepwater, qhov twg dej tob feem ntau tshaj 2,000 meters. Nyob rau hauv cov cheeb tsam no, kev nkag ncaj qha mus rau subsea wellheads yog tsis muaj peev xwm tsis muaj ib tug conduit system muaj peev xwm tuav dynamic marine motions, hydrostatic pressures, thiab kua rov qab. Nruab nrog tensioning systems thiab advanced sealing technologies, cov drilling risers kom muaj kev ruaj ntseg zoo tswj thiab ua tau zoo drilling kev ua tau zoo nyob rau hauv ib co ntawm cov feem ntau xav tau offshore tej yam kev mob.
Drilling Riser Specifications thiab Functions
Qhov drilling riser feem ntau tau piav qhia tias yog txoj hlua khi ntawm qhov chaw drilling nto thiab lub qhov dej hauv dej hiav txwv. Nws cov dej num mus dhau qhov muab cov kav dej yooj yim; plays lub luag haujlwm ntau yam hauv kev ua kom muaj kev nyab xeeb, kev ua haujlwm zoo thiab kev tswj xyuas kev ua haujlwm ntawm ntug dej hiav txwv:Drilling kua ncig
Lub riser muab txoj hauv kev txuas mus ntxiv rau cov dej ntws los ntawm cov dej hauv qab dej rov qab mus rau lub platform.
Tso cai tshem tawm ntawm cuttings, txias ntawm me ntsis thiab stabilization ntawm lub qhov dej.
Nyob rau hauv cov dej tob, qhov kev ua haujlwm no yog qhov tseem ceeb vim tias cov av nkos yuav tsum sib npaug ntawm kev tsim cov kev ntxhov siab thaum tswj kev ruaj khov ntawm qhov ntev ntsug.
Kev tswj siab thiab kev ncaj ncees zoo
- Lub riser txuas lub subsea blowout inhibiter (BOP) los ua ke rau lub platform lub zoo tswj system, cia cov neeg ua hauj lwm nto kaw nyob rau hauv lub qhov dej yog hais tias txawv txav tej yam kev mob tshwm sim.
- Los ntawm vaj tse choke thiab tua kab raws nws sab nrauv, tus riser kuj tso cai rau cov neeg ua haujlwm saib xyuas cov kev ua haujlwm zoo, ncig ncaws pob, thiab txhaj cov kua dej ncaj qha rau hauv lub qhov dej thaum tsim nyog.
- Qhov kev tswj lub siab no ua rau cov riser yog lub hauv paus hauv kev tiv thaiv kev ncaj ncees ntawm qhov dej.
Dynamic yoog raws thiab kev them nyiaj ua haujlwm
- Offshore platforms raug rau ib puag ncig kev txav los ntawm nthwv dej, cua thiab dej ntws.
- Lub riser yog tsim los nrog tensioning systems, hloov tau cov pob qij txha thiab buoyancy modules kom haum rau ntsug suab thiab lateral deviations.
- Cov khoom no tuav lub verticality ntawm lub riser thiab tiv thaiv lub subsea wellhead los ntawm ntau flexing los yog qaug zog.
Ib ntus tab sis reusable infrastructure
- Tsis zoo li cov hlua txuas mus tas li, qhov drilling riser tau zoo dua tom qab drilling qhov dej.
- Nrog rau kev tshuaj xyuas kom zoo, rov kho dua thiab rov ua dua tshiab, cov pob qij txha riser tuaj yeem rov qab siv tau rau hauv ntau qhov dej, ua rau nws muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo nyob sab nraud.
