Hauv cov roj thiab roj siv zoo,Cementing Projectyog ib txheej txheem tseem ceeb tau siv kom ruaj ntseg qhov chaw zoo, cais tawm kev tsim, thiab ua kom muaj kev sib tham ntev ntawm lub qhov dej. sib txawvHom cementingcov haujlwm tau siv nyob ntawm cov qauv tsim tau zoo, kev tsim cov ntsiab lus, thiab cov hom kev ua haujlwm tshaj plaws hauv cov roj av . thiab covKev Ua Yeeb Yam Ntxiv Ntxiv thiab cementing kuaj cov twj yog qhov tseem ceeb rau txhua hom ntawm cov kev ua haujlwm cement .

{1. cementing

Cementing thawjyog thawj zaug thiab tseem ceeb tshaj plaws ua haujlwm rau kev ua haujlwm ua haujlwm} Tom qab lub ntsej muag yog tso rau hauv qhov chaw nyob nruab nrab ntawm lub casing thiab}} ib zaug teeb, cov cement:

Muab cov qauv kev txhawb nqa rau lub casing

Ntsaws Nplig tawm cov kua dej

Tiv thaiv cov casing los ntawm corrosion

Txoj kev ua haujlwm no ua kom zonal kev cais tawm thiab yog lub hauv paus ntawm kev ua tiav zoo .

🔧 2. Kev cem Cementing

Kuj hu uaKho Kho Kom Yooj Yim, Kho Kom Zam Tximyog siv thaum thawj cov cement tsis ua tiav kom ua tiav lub zonal kev sib cais {{}} nws suav nrog:

Nyem cementing: Yuam kom xis mas nyob rau hauv siab mus rau hauv cov kua qaub, raws, lossis puas yog aones rau kaw lawv

Ntsaws Plemasing: Xa cov Maas ntsaws rau ntawm ib qho tob rau cais ib cheeb tsam lossis kaw ib ntus kaw hauv cov dej

Kho kom rov qab kho kom zoo rov qab txoj kev ntseeg siab thiab tiv thaiv cov kua dej tsiv teb tsaws chaw .

🔁 3.} theem cementing

Theem Cementingyog siv thaum ib feem-txoj hauj lwm cement tsis txaus, feem ntau yog ib puag ncig ntawm cov cuab yeej siv cov cuab yeej tshwj xeeb hu ua theem tshwj xeeb. qhov no:

Txo qhov siab ntawm cov qauv tsis muaj zog

Tso cai rau kev xaiv ntawm cov cement

Txhim Kho Kev Sib Raug Zoo thiab Zonal Kev Ruaj Ntseg

{{{0} }log cement (plug-)

Ntsaws Plemasingyuav muab tso rau aMAAs PlugNyob rau hauv qhov chaw nyob zoo . Nws siv rau:

Abandoning ib tug zoo

Teeb tsa lub hauv paus rau yav tom ntej drilling

Cais ib cheeb tsam rau kev sim lossis perforation

Nws yog qhov yooj yim tab sis tseem ceeb ua haujlwm rau kev tswj tau zoo thiab hloov tau .

5. rov qab los ntawm kev ua paj yeeb

HauvNrig ncig ua yeeb ncig, Maas slurry yog twj tso tawm ntawm cov annuldus thiab ntws rov qab lub casing . nws feem ntau siv nyob rau hauv:

Cov dej ntiav

Tsawg-siab tsim

Cov xwm txheej uas cov txheej txheem uas muaj kev phom sij txaus ntshai

Cov qauv no txo ​​qhov sib npaug sib npaug ntawm cov ntom ntom ntom (ECD) thiab pab kom tsis txhob ploj kev ncig {}}

{6. foamed cementing

Hauvfoamed cementing, roj (feem ntau nitrogen) yog tov nrog xis mas slurry kom txo nws ntom ntom {}} nws siv nyob rau hauv:

Tsawg-siab los yog depleted reservoirs

Zones siv cov kua dej ploj

Cov dej uas yuav tsum tau ua rau lub teeb, kev nthuav dav loj

Foisted xis mas muab cov rwb thaiv tsev zoo thiab elastic khoom .

{7. liner cementing

Liner cementingyog ua thaum tus nqi luv luv ntawm casing (liner) tau nruab dua es khiav puv-ntev casing {}} nws:

Saves cov nqi ntawm cov ntaub ntawv

Tso cai rau kev tiv thaiv kev tiv thaiv zoo

Txo casing diam thiab qhov hnyav

Cov xis mas muab tso rau ib ncig ntawm lub liner kom ntseeg tau tias kev tsim kom zoo nrog kev tsim .

✅ Qhov xaus

Txhua hom cementing plays lub luag hauj lwm tseem ceeb nyob rau hauv cov kev tsim kho zoo thiab ntau lawm}
