Oldfield Cementing yog qhov ua haujlwm tseem ceeb hauv kev tsim cov khoom noj kom zoo nkauj thiab cov khoom siv tsis zoo, txhawb nqa cov khoom siv uas ua kom muaj roj thiab tiv thaiv roj thiab roj txau {. cementing plays lub luag haujlwm ntawm lub qhov dej siab ntev, thiab tiv thaiv ib puag ncig.
Cov Cheebtsam ntawm Cementing
Maas Slurry System
Lub hauv paus Maas:Feem ntau, cov ntaub ntawv Portland uas tau raws li cov qauv siv hluav taws xob Asmeskas (API) xws li kub thiab txias, thiab tsim cov yam ntxwv ....
Maas Cos ntxiv:
Cov kua dej ntxiv:Cov yeeb yaj kiab ntxiv no yog cov yeeb yaj kiab tiv thaiv ntawm Caas hais los tswj cov dej poob hauv kev tsim, tiv thaiv cov pob zeb polymer thiab cellulose {{3}
Tus sawv cev:Cov no ncua lub sijhawm teeb tsa lub sij hawm ntawm cov cement slurry, uas yog qhov tshwj xeeb tshaj yog rau kev ua ntej ntxov los yog cov accoxycarboxylic actarders .
Accelerators:Cov kev ua tau zoo li cov kev teeb tsa thiab kev txhim kho lub zog pub rau kev tso cai sai sai. Cov Ciaj Tshuaj Calcium suav nrog cov calcium chloride thiab triethanolamine.
Kev sib txhuam Reducers:Cov no txo cov kev tso tawm thaum lub cev ntas qis dua, txo cov twj tso tawm dua thiab txhim kho kev ua haujlwm ntawm cov slurry.
Qhov hnyav thiab cov neeg sawv cev me me:Cov neeg sawv cev nyhav (e {{{0} g {}}, hollow iav kev ceev kom tsis txhob poob siab nyob rau hauv qis-siab formations.
Casing thiab downhole cov cuab yeej
:Steel yeeb nkab qauv tso rau hauv qhov chaw zov me nyuam muab cov qauv kev txhawb nqa thiab tsim kev ntws rau cov roj thiab roj thaum ua kom huv si hauv qhov chaw .
Cov ntsiab lus:Cov khoom siv uas khaws lub teeb rau hauv qhov chaw nyab xeeb, tso cai txawm tias kev faib ua kom xis nyob kom ua tiav thiab ua kom muaj kev tsim kom tiav ntawm sheath {}}
Lub luag haujlwm thiab cov khoom siv ntawm cov chaw soj nasing
Cementing labs ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo nkauj ua kom zoo thiab nce qib {{}} Cov khoom tseem ceeb suav nrog:
Kev kub siab-siab-siab fetometer:Simulates downhole kev mob los sim thickening lub sij hawm thiab rheology ntawm Maas slurry, tshuaj xyuas tus cwj pwm thiab kev teeb tsa tus cwj pwm .
Kho Chamber:Cov xwm txheej cement txoj kev ntsuas nyob rau hauv kev tswj kub thiab siab rau mimic downhole ib puag ncig, tso cai rau kev ntsuas kev sim .
Dag Zog Kuaj Tshuab:Kev ntsuas kev sib xyaw ua ke thiab flexural lub zog ntawm cov tshuaj xis ua kom ntseeg tau tias yog cov ntxhib hluav taws xob ntawm cov xasas sheath .
Permeberility Tester:Ntsuas lub peev xwm ntawm kev teeb tsa MAAs kom raug kaw cov kua dej, kom meej meej zonal cais .
Particle loj tsom kwm:Ntsuas cov particle loj faib cov cement thiab cov ntxiv kom nkag siab zoo dua lawv cov khoom thiab ua kom zoo rau .
TOV KHOOM:Kev ua kom meej yooj yim xis mas, dej, thiab ntxiv los npaj homogeneous xiss me ntsis kev kuaj mob .
Hom thiab cov nyom ntawm kev ua yeeb yam
Hom cementing
Qaum Teb:Thawj cov txheej txheem ntawm kev nqus cov cement rau hauv qhov chaw nyab xeeb kom tawm tsam thiab txhawb nqa casing casing .
Ntsej Muag Alement "Siv rau kev ua haujlwm kom rov kho xws li kev kho teeb meem los ntawm txoj hauj lwm Maas (e}} g}}
Cov kev sib tw hauv kev ua yeeb yam
Nyuaj geology:Kev kub siab / cov kev tsim kev kub siab, cov ntsev uas yuav tsum tau ua kom haum Maas cov peev txheej thiab cov kev kawm ua kom tiav cement.
Kev Pheej Liaj Ua Haujlwm:Cov teeb meem xws li teeb tsa ua ntej ntxov, ploj ntawm kev ncig, lossis slurry thaiv tuaj yeem ua rau cov cement tsis txaus thiab poob nyiaj tseem ceeb .
Oilfield Caement Ua cov ntaub ntawv Scients, kev tsim kho cov tshuab thiab kev sim ua haujlwm ntawm cov roj thiab roj kev pabcuam kom zoo ntawm cov roj thiab roj kev pab cuam.
