Ukusetyenziswa kwe-CMC kuLwalulo lokuNyonjwa

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 lokutyebisa, kwimeko yomxholo ophantsi wokususwa komhlaba, 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 kwamanzi kwi-shale yodaka eludongeni lwequla, kunye nesiphumo sokugquma se-CMC samatyathanga 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 into yokutshixa kwamanzi, okanye kubangele ukuba indawo enodaka kumaleko we-oyile yande, iphazamise ukungeneka 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.
