Hauv cov lus yooj yim, qhovLSAWCov txheej txheem tsim khoom suav nrog kev khoov cov phaj hlau ua ib lub raj thiab tom qab ntawd siv kev vuam submerged arc los vuam cov npoo ntawm cov phaj hlau ua ke los ua ib lub yeeb nkab hlau.
Tom ntej no, peb yuav coj koj mus rau cov kauj ruam tseem ceeb hauv kev tsim cov kav hlau LSAW, muab rau koj nkag siab meej txog cov txheej txheem.
1. Kev tshuaj xyuas thiab txiav phajNyob ntawm cov qauv kev siv yeeb nkab hlau thiab qhov loj me uas xav tau, cov phaj tsim nyog yuav raug txiav ua qhov loj me uas tsim nyog.
2. Kev txiav ntugUa kom ntug ntawm cov yeeb nkab hlau zoo li tus V. Kauj ruam no tseem ceeb heev rau qhov zoo ntawm qhov vuam.
3. TsimPeb lub tuam txhab siv cov txheej txheem tsim JCOE, uas cov hlau phaj raug tsim los ua cov qauv tubular txuas ntxiv los ntawm cov menyuam thiab lub tshuab nias.
4.Kev vuamHauv qhov ntev ntawm cov qauv tubular, kev vuam submerged arc yog ua los ntawm kev sib txuas cov npoo ntawm cov phaj hlau los ua cov yeeb nkab hlau. Qhov no yog kauj ruam tseem ceeb tshaj plaws hauv tag nrho cov txheej txheem.
5. Kev Tshuaj Xyuas: Muaj ntau qhov kev tshuaj xyuas, suav nrog 100% kev sim tsis puas tsuaj thiab kev sim hydrostatic leak ntawm cov kav dej hlau, xyuas kom meej tias cov khoom tiav lawm ua tau raws li cov qauv.
Hauv cov txheej txheem tsim cov kav hlau LSAW tiag tiag, ntxiv rau cov txheej txheem tseem ceeb uas tau hais los saum toj no, muaj ntau lwm cov kauj ruam zoo thiab nyuaj. Cov kauj ruam no xav tau kev tswj hwm kom meej thiab kev saib xyuas zoo kom ntseeg tau tias kev tsim cov kav hlau LSAW zoo uas ua tau raws li cov qauv.
1. Hloov tau yooj yim heevCov kav hlau LSAW feem ntau siv rau hauv qhov chaw ua haujlwm kub thiab siab. Nrog rau cov txheej txheem tsim nyog, cov kav dej no tuaj yeem ua haujlwm tau zoo txawm tias nyob rau hauv huab cua hnyav thiab cov xwm txheej geological nyuaj.
2. Kev vuam zooHauv kev tsim cov LSAW, covOb Sab Submerged Arc Vuam (DSAW)siv cov txheej txheem no. Cov txheej txheem no ua kom ntseeg tau tias qhov vuam tau nkag mus tag nrho, yog li ua tiav cov qauv siab ntawm kev vuam zoo. Qhov vuam yog sib xws thiab sib xws, ntxiv txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm cov yeeb nkab hlau.
3. Cov yeeb nkab hlau loj uas muaj phab ntsa tuab:
| Cov lus luv luv | Lub Npe | Txoj kab uas hla sab nraud | Phab ntsa tuab |
| SSAW (HSAW, SAWH) | Kev Sib Txuas Arc Sib Txuas | 200 - 3500 hli | 5 - 25 hli |
| LSAW (SAWL) | Kev Vuam Arc Ntev Ntev | 350 - 1500 hli | 8 - 80 hli |
| ERW | Hluav Taws Xob Tiv Thaiv Welded | 20 - 660 hli | 2 - 20 hli |
| SMLS | Tsis muaj qhov sib txuas | 13.1 - 660 hli | 2 - 100 hli |
Raws li pom tau los ntawm kev sib piv qhov loj me ntawm cov khoom saum toj no, LSAW cov kav hlau muaj qhov zoo pom tseeb hauv kev tsim cov kav hlau loj uas muaj phab ntsa tuab, ua tau raws li qhov xav tau ntawm cov haujlwm loj thiab cov ntawv thov kev lag luam.
4. Siv dav: Cov kav hlau LSAW siv dav hauv kev xa roj thiab roj, kev tsim kho vaj tse, kev tsim kho choj, thiab lwm yam uas xav tau cov kav hlau muaj zog vim lawv lub zog siab thiab kev ua tau zoo heev.
