Nyob rau hauv cov roj thiab roj kev loj hlob, cementing yog kev ua haujlwm tseem ceeb uas ua kom muaj kev ruaj khov muaj zog thiab cais cov cheeb tsam hydrocarbon. Qhov zoo ntawm cementing ncaj qha seb qhov zoo tuaj yeem ua haujlwm nyab xeeb thiab muaj txiaj ntsig zoo rau lub sijhawm ntev. Txhawm rau lav qhov zoo, kev kuaj sim yog qhov tseem ceeb. Niaj hnub no, cia saib cov khoom siv tseem ceeb uas siv hauv kev ua haujlwm hauv chaw soj nstas, thiab seb lawv safeard muaj kev ncaj ncees nyob tom qab cov scenes.
Vim li cas peb thiaj li xav tau lub chaw kuaj ua kom xis nyob?
Cov Maas Slurry siv hauv kev ua kom zoo nkauj yuav tsum ua kom tiav cov cai nruj rauRheology, thickening lub sij hawm, lub zog compressive, thiab kua -}} poob ua tauCov. Txhua qhov kev sib txawv ntawm cov tsis muaj peev xwm ua rau cienting tsis ua tiav, ua rau muaj teeb meem xws li ploj kev ncig, nuj nqis, lossis txawm tias tag nrho cov kev tso tseg zoo.
Lub caventing Laboratory, nruab nrog cov khoom siv tshwj xeeb, tso cai rau cov engineers rausimulate, saib xyuas, thiab ua kom zoocement slurry formulations. Qhov no muab kev txhawb nqa rau kev txhawb nqa rau cov haujlwm, txo qis, thiab ua kom muaj kev kub siab.
Cov Khoom Siv Hauv Lub Chaw Haujlwm Ntseeg Cementing
1. Qhov kev tov khoom ceev tas li
Cov tov khoom yog cov khoom siv yooj yim tshaj plaws, siv los npaj cov cement cov qauv ntawm cov qauv raws cov txheej txheem txheem. Nws ua kom muaj kev sib xyaw ua ke, tiv thaiv clumps lossis kev sib cais, thiab muab cov qauv sib xws, rov ua dua tshiab rau kev sim tom ntej.
2. Atmospherric Metometer
Cov cuab yeej no yog siv los kho thiab kuaj cov khoom sib xws ntawm cov cement slurry ntawm qhov kub cua sov thiab siab. Txawm hais tias nws tsis tuaj yeem hloov kho qhov xwm txheej huab cua sov, nws ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb ua ntej thiab kev tshawb fawb sib piv.
3. Rheameter - rheology kev sim
Cov khoom siv RHE RHE txaus nrog cov khoom xws li viscosity, tawm tsam kev ntxhov siab, thiab cov viscosity yas. Cov kev txwv no txiav txim siab seb cov slurry slurry tuaj yeem tso tau yooj yim rau hauv qhov chaw nkaum. Nws tseem ntsuasgel lub zog, uas ntsuas cov qauv tsim tsim nyob rau lub sijhawm zoo li qub, tiv thaiv kom tsis txhob sib txuas thiab ua kom xis nyob kom xis mas.
4. Cov kua dej zoo li qub -} tsis txawj tester
Qhov ntsuas no ntsuas qhov ntau ntawm kev poob ntawm cov slurry nyob rau hauv cov xwm txheej zoo li qub. Kev ua kua dej ntau dhau tuaj yeem ua rau ua kom ntxov ua kom huv thiab lim}}} Ncuav mog qab zib zoo, thaum kawg hloov khoom qab zib. Kev xeem yuav pab cov kws tshaj lij ua kom zoo slurry tsim rau kev txhim kho cov kua {}}} tsis tswj.
5.HKT METSTOMETAL
Ib qho ntawm cov twj tseem ceeb tshaj plaws nyob rau hauv ib qho kev kawm cementing, tusSiab - siab high - kub (HPHT) MeterometerSimulates cov chaw nyob ze rau ib puag ncig los txiav txim slurry thickening sijhawm. Qhov no ua kom muaj cov slurry tseem muab zais tsis pub dhau lubKev Nyab Xeeb Kev Nyab Xeeb Qhov rai, txo cov kev pheej hmoo ntawm kev ua ntej ntxov lossis ncua chaw.
6. Pauv thaiv cov tshuab kho
HPHT kho Chamber: Siv los ntxuav cov cave kuaj hauv qab high - qhov kub thiab txias, ua kom cov pob zeb ua kom haum.
Cov Tshuaj Tiv Thaiv ATMOSPRICCER: Siv rau kev kho tau raws li qhov chaw nkaum ntawm huab cua siab, haum rau cov kev tshawb fawb yooj yim thiab kev sib piv.
Cov hau kev no muab cov qauv txhim khu kev qha rau kev kuaj lub zog tom ntej thiab kev ntsuas permeability.
7.Cov Tuag Zog Analyer
Cov ntsuas no ntsuas ntsuas lub thawv thauj khoom - Cov kabmob muaj peev xwm ntawm kev coement. Nws pab ntsuas seb cov xis mas tuaj yeem tiv thaiv qis qis, tiv thaiv kev sib tsoo, thiab tswj hwm txoj kev ncaj ncees.
8.ulrasonic zoo li qub gel / zog analyzer
Siv cov thev naus laus zis ultrasonic, cov cuab yeej no tsis tu ncua thiab tsis -}} kev hloov pauv ntawm slurry kom teeb tsa. Nws generates tiag - lub sij hawm} lub sijhawm ua kom muaj zog kev nkhaus, ua rau nws muaj txiaj ntsig tshwj xeeb tshaj plaws rau kev kawmThaum Ntxov Muaj Zog TauthiabKev coj tus cwj pwm zoo li qub, muab ntau qhov kev pom tseeb ntxiv rau hauv cov kev ua tiav.
Tus nqi ntawm cov chaw soj ntsuam kev ua haujlwm
Nrog cov cuab yeej siab tshaj plaws, engineers tuaj yeem:
Txhim kho Mement Slurry Formulationskom haum ntau qhov kev ua haujlwm geological.
Kwv yees cov kev pheej hmoo cementing ua ntej, txo qhov ntxim nyiam ntawm downhole kev huam yuaj.
Tau txais cov qauv ntaub ntawv xeem, Muab kev tshawb fawb txog kev ua haujlwm.
Cementing lub chaw soj ntsuam tsis yog tsuas yog tseem ceeb ntawm kev tshawb fawb cov chaw tshawb fawb tab sis kuj xaiv cov khoom muaj peev xwm rau cov neeg ua haujlwm Oilfield los txhim kho kev ua kom zoo thiab ua kom muaj kev tsim kev nyab xeeb.
