Khoom Description LEANOS
Odex casing system yog ib hom kev drilling tshuab siv nyob rau hauv thaj chaw ntawm geotechnical engineering thiab ntxhia tshawb nrhiav. Nws yog ib tug down-qhov rauj drilling txoj kev uas tso cai rau lub drilling ntawm boreholes nyob rau hauv nyuaj pob zeb formations. Lub kaw lus muaj ib qho kev xyaum tshwj xeeb uas tau tsav mus rau hauv lub pob zeb los ntawm lub pob zeb percussion, thiab lub casing uas yog ib txhij mus rau hauv lub borehole los tiv thaiv lub qhov los ntawm kev sib tsoo.
Odex casing system yog tsim los siv rau hauv qhov nyuaj drilling, xws li pob zeb tawg thiab tsis ruaj khov. Lub kaw lus tso cai rau kev ua haujlwm zoo dua thiab nrawm dua, vim tias nws tshem tawm qhov xav tau ntawm cov dej drilling thiab lwm yam kev txhawb nqa. Nws kuj tseem txo qhov kev pheej hmoo ntawm borehole vau thiab ua rau nws muaj peev xwm muab cov av tsis muaj kev cuam tshuam thiab cov qauv pob zeb rau kev sim.
Cov khoom siv LEANOS
Rau casing drilling nyob rau hauv cov xwm txheej hauv av, Odex Casing System yog qhov kev xaiv zoo tshaj plaws. Lawv tshwj xeeb tshaj yog nyiam los ntawm cov neeg ua haujlwm drilling rau kev ua haujlwm ntiav micro-piling, casing hauv dej thiab dej kub hauv qhov dej, thiab qhov nruab nrab qhov loj me rau cov tsev,
dams, harbor tej yaam num, thiab geothermal qhov dej. Lub ntse reaming tis ua rau nws muaj peev xwm muab tau thiab rov qab siv me ntsis. Odex Casing System yog qhov zoo tshaj plaws rau drilling qhov me me nyob rau hauv cov khaub ncaws overburden vim nws cov txiaj ntsig zoo, xws li nws cov qauv ncaj nraim, kev tswj tau yooj yim, cov khoom siv drilling rov qab tau ntev, kev pab lub neej ntev, thiab zoo. Odex Casing System muaj cov cuab yeej drilling zoo ib yam li cov txheej txheem DTH rauj drilling, xws li:
1. Cuttings raug tshem tawm sai;
2. Kev nkag siab siab, tshwj xeeb tshaj yog nyob rau hauv basalt thiab lwm yam nyuaj pob zeb formations;
3. yooj yim hauv av thiab av qauv thaum drilling;
4. Muaj peev xwm ntsuas qhov kev kwv yees ntawm qhov kev xaiv qhov tob;
5. Txaus siab rau hauv cov txheej txheem uas tsis zoo sib sau ua ke thiab muaj kev pheej hmoo siab ntawm kev tawg (qhov no yog qhov tseem ceeb tshaj plaws).
Odex (Overburden Drilling System nrog Excentric drilling) casing system yog lub tshuab drilling siv nyob rau hauv cov xwm txheej uas muaj xoob overburden lossis tsis ruaj khov hauv av, xws li hauv kev tsuas, kev tsim kho, thiab kev tshawb nrhiav geotechnical.
Kev faib khoom LEANOS
ODEX casing systems feem ntau yog siv rau hauv geotechnical thiab ib puag ncig drilling daim ntawv thov qhov twg lub borehole yuav tsum tau drilled los ntawm unstable los yog nyuaj-rau-drill formations. CovODEX casing system yog tsim los muab kev ruaj ntseg borehole thiab tiv thaiv lub borehole los ntawm kev sib tsoo.
ODEX casing systems yog siv rau hauv kev ua haujlwm drilling los tiv thaiv cov dej poob thiab ruaj khov ntawm qhov dej. Lawv raug cais raws li lawv tus qauv tsim thiab kev ua haujlwm. Nov yog qee qhov kev faib tawm ntawm eccentric casing systems:
Pa Casing System: Qhov system no yog hom yooj yim tshaj plaws ntawmODEX casing system. Nws muaj ib qho eccentric ntab khau thiab ib txoj hlua casing. Cov khau ntab yog nyob rau hauv qab ntawm txoj hlua casing thiab yog tsim los coj lub casing mus rau qhov chaw ntawm lub qhov dej.
Ntau ODEX Casing System: Cov kab ke no muaj ntau yam khau eccentric ntab thiab cov hlua casing. Cov khau ntab yog muab tso rau ntawm qhov sib txawv ntawm cov hlua khi kom tiv thaiv kom tsis txhob muaj dej thiab ua kom lub qhov dej ruaj khov.
Ib Leeg Joint ODEX Casing System: Qhov system no muaj ib qho kev sib koom ua ke ntawm casing nrog ib qho eccentric ntab khau txuas rau nws. Cov khau float yog tsim los coj lub casing mus rau qhov chaw ntawm lub qhov dej.
Multi-Stage ODEX Casing System: Cov txheej txheem no yog siv rau hauv kev ua haujlwm drilling nyuaj uas yuav tsum muaj ntau txoj hlua casing. Nws muaj ntau yam eccentric ntab khau tso rau ntawm qhov sib txawv hauv txhua txoj hlua khi kom tiv thaiv cov dej tsis zoo thiab ua kom lub qhov dej ruaj khov.
Reaming ODEX Casing System: Qhov system no yog siv los ua kom lub qhov dej loj. Nws muaj ib txoj hlua casing nrog cov cuab yeej reaming txuas rau hauv qab. Cov cuab yeej yog tsim los rau ream lub wellbore thiab tsim ib tug eccentric annulus ntawm lub casing thiab lub wellbore phab ntsa.
Rov qab Circulation ODEX Casing System: Qhov system no yog siv rau hauv kev ua haujlwm drilling qhov twg cov kua dej ntau yuav tsum tau nthuav tawm. Nws muaj ib txoj hlua casing nrog cov khau eccentric ntab txuas rau hauv qab. Cov khau ntab yog tsim los tsim kom muaj qhov thim rov qab ntawm cov kua dej tawm ntawm lub annulus, uas yog tom qab ntawd rov qab mus rau hauv cov yeeb nkab laum.
