Carboxymethyl cellulose CMCngumgubo omhlophe weflocculent osebenza ngokuzinzileyo kwaye unyibilika ngokulula emanzini. Isisombululo silulwelo lwe-viscous olungathathi hlangothi okanye lwe-alkaline, oluhambelana nezinye iiglues kunye ne-resins ezinyibilikayo emanzini. Imveliso ingasetyenziselwa i-adhesive , thickener, suspending agent, emulsifier, dispersant, stabilizer, sing agent, njl. I-Carboxymethyl cellulose isetyenziswa kwi-petroleum kunye negesi yendalo yokwemba, ukumba kakuhle kunye nezinye iiprojekthi.
Indima ye-carboxymethyl cellulose CMC: 1. Udaka oluqulethe i-CMC lunokwenza udonga lomthombo lube yikhekhe lokucoca olubhityileyo kunye noluqinileyo kunye nokungena okuphantsi, ukunciphisa ukulahlekelwa kwamanzi. 2. Emva kokongeza i-CMC eludakeni, i-drilling rig inokufumana amandla okucheba aphantsi okuqala, ukwenzela ukuba udaka lukwazi ukukhulula lula igesi ehlanganiswe kuyo, kwaye kwangaxeshanye, i-debris ingalahlwa ngokukhawuleza emgodini wodaka. 3. Ukugrumba udaka, njengezinye izinto zokuxhoma kunye nokusabalalisa, kunobomi beshelufu. Ukongeza i-CMC ingayenza izinze kwaye yandise ubomi beshelufu. 4. Udaka oluqukethe i-CMC alufane luchaphazeleke ngumbumba, ngoko akuyomfuneko ukugcina ixabiso eliphezulu le-pH kunye nokusebenzisa izilondolozo. 5. Iqulethe i-CMC njenge-arhente yonyango yokwemba ulwelo lokugungxulwa ngodaka, olunokuxhathisa ukungcoliseka kweetyuwa ezahlukeneyo ezinyibilikayo. 6. Udaka oluqulathe i-CMC lunozinzo oluhle kwaye lunokunciphisa ilahleko yamanzi nokuba ubushushu bungaphezu kwe-150°C. I-CMC ene-viscosity ephezulu kunye neqondo eliphezulu lokutshintshela ilungele udaka olunoxinano oluphantsi, kunye ne-CMC ene-viscosity ephantsi kunye neqondo eliphezulu lokutshintshela lilungele udaka olunoxinano oluphezulu. Ukhetho lweCMC kufuneka lumiselwe ngokweemeko ezahlukeneyo ezifana nodidi lodaka, indawo, kunye nobunzulu bequla.
Ukusetyenziswa kwe-CMC kuLwalulo lokuNyonjwa
1. Ukusebenza okuphuculweyo kwelahleko yesihluzi kunye nomgangatho wekeyiki yodaka, ukuphuculwa kobuchule bokuchasana nokubanjwa.
I-CMC sisinciphisi esilungileyo sokulahleka kolwelo. Ukuyongeza edakeni kuya kwandisa i-viscosity yesigaba se-liquid, ngaloo ndlela kwandisa ukuchasana kwe-seapage ye-filtrate, ngoko ukulahlekelwa kwamanzi kuya kuncitshiswa.
Ukongezwa kwe-CMC kwenza ukuba ikeyiki yodaka ixinene, iqine kwaye igudiswe, ngaloo ndlela inciphisa into eyenzeka kwi-jamming yoxinzelelo oluhlukeneyo kunye nesixhobo sokugaya intshukumo ekude, ukunciphisa umzuzu wokuxhathisa kwintonga ye-aluminiyam ejikelezayo kunye nokunciphisa into yokufunxa equleni.
Ngokubanzi udaka, inani lemveliso ye-CMC ephakathi kwe-viscous yi-0.2-0.3%, kwaye i-API yokulahlekelwa kwamanzi iyancipha kakhulu.
2. Ukuphuculwa kwesiphumo sokuthwala amatye kunye nokwanda kozinzo lodaka.
Ngenxa yokuba i-CMC inekhono elihle lokujiya, kwimeko yesiqulatho sokususa umhlaba ophantsi, ukongeza inani elifanelekileyo le-CMC kwanele ukugcina i-viscosity efunekayo ukuthwala ukusika kunye nokumisa i-barite, kunye nokuphucula ukuzinza kodaka.
3. Ukuxhathisa ukusasazwa kodongwe kwaye uncede ukuthintela ukuwa
Ilahleko yamanzi ye-CMC yokunciphisa ukusebenza icothisa izinga lokugalela kodaka lwe-shale eludongeni lwequla, kunye nesiphumo sokugquma seCMC amatyathanga amade kwilitye lodonga lomthombo womeleza ulwakhiwo lwamatye kwaye lwenza kube nzima ukuxobula nokudilika.
4. I-CMC yiarhente yonyango lodaka ehambelanayo
I-CMC ingasetyenziswa ngokudibeneyo kunye neearhente zonyango ezahlukeneyo eludakeni lweenkqubo ezahlukeneyo, kwaye ifumana iziphumo ezilungileyo.
5. Ukusetyenziswa kwe-CMC kulwelo lwesamente kwi-spacer
Ulwakhiwo oluqhelekileyo lokufakwa kwesamente kunye nesitofu sesamente yinxalenye ebalulekileyo yokuqinisekisa umgangatho wesamente. I-spacer fluid elungiselelwe yi-CMC ineenzuzo zokunciphisa ukuchasana nokuhamba kunye nokwakhiwa okufanelekileyo.
6. Ukusetyenziswa kwe-CMC kulwelo lomsebenzi
Ekuvavanyeni ioli kunye nokusebenza komsebenzi, ukuba udaka oluphezulu lusetyenziswa, luya kubangela ukungcola okunzulu kwi-oyile, kwaye kuya kuba nzima ukuphelisa olu ngcoliseko. Ukuba amanzi acocekileyo okanye i-brine isetyenziswa nje njengolwelo olusebenzayo, kuya kwenzeka ungcoliseko olukhulu. Ukuvuza kunye nelahleko yokuhluzwa kwamanzi kumaleko e-oyile kuya kubangela ukuba kutshixeke amanzi, okanye kubangele ukuba indawo enodaka kumandlalo we-oyile yande, iphazamise ukunyanzeliswa komgangatho we-oyile, kwaye izise uthotho lobunzima emsebenzini.
I-CMC isetyenziswa kulwelo olusebenzayo, olunokusombulula ngempumelelo ezi ngxaki zingasentla. Kwimithombo yoxinzelelo oluphantsi okanye amaqula oxinzelelo oluphezulu, ifomula inokukhethwa ngokwemeko yokuvuza:
Uluhlu loxinzelelo oluphantsi: ukuvuza okuncinci: amanzi acocekileyo + 0.5-0.7% CMC; ukuvuza ngokubanzi: amanzi acocekileyo + 1.09-1.2% CMC; ukuvuza okunzulu: amanzi acocekileyo + 1.5% CMC.
