Iyini indima ye-CMC njengoketshezi lokulahleka koketshezi kumanzi okumba?

I-Carboxymethyl Cellulose (CMC) yi-ejenti yokulahlekelwa uketshezi esetshenziswa kakhulu kumanzi okumba. Njengesengezo esibalulekile samakhemikhali, indima enkulu ye-CMC ku-Drilling Fluids ukulawula ukulahleka koketshezi, ithuthukise ukusebenza koketshezi lokumba, ukuvikela izindonga ezinhle, futhi kugcinwe ukuqina nokuphepha kokumba.

1. Lawula ukulahleka kokuhlunga
Ukulahleka kwama-fluid kubhekisele enanini le-drive fluid egcwele ekwakhekeni. Ukulahlekelwa ngokweqile kwe-fluid kungaholela ekwakhekeni kokungalingani, okungaholela ekuweni kahle odongeni kanye nezinye izinkinga. Njengokwehliswa koketshezi, i-CMC yakha isendlalelo esivikelayo esibonakalayo ku-fluid evuthayo, okunciphisa ngempumelelo inani lamanzi ofuziswe uketshezi olungena ngaphakathi, ngaleyo ndlela elawula ukulahleka koketshezi. Losendlalelo ovikelayo ungakha ikhekhe eliminyene lokuhlunga ngaphezulu kokwakheka ukuvikela amanzi oketshezi oludonsayo kusuka ekungeneni ekwakhiweni.

2. Khulisa ukubonakala koketshezi lokumba
I-CMC ingakhulisa kakhulu i-viscosity yohlobo lokumba futhi ithuthukise amandla ayo okuphatha izithombo zokusika nezinhlayiya eziqinile. Lokhu kubalulekile ukuze ususe imfucumfucu kusuka phansi komthombo futhi ugcine umthombo u-Wellbore uhlanzekile. I-viscosity efanele futhi ingavimba ukuwa kahle kahle futhi iqinisekise ukusebenza okubushelelezi.

3. Vikela odongeni kahle
Ngesikhathi senqubo yokumba, ukuqina kodonga kahle kubaluleke kakhulu. I-CMC ivikela ngempumelelo udonga kahle ngokwakha ifilimu evikelayo endaweni ephezulu yodonga ukuze kuncishiswe ukuguguleka nokuguguleka kodonga kahle ngokudonsa uketshezi. Lokhu kusiza ukugwema izingozi ezifana nokuwa odongeni kanye nokusakazwa, futhi kuqinisekisa ukuphepha nokuqhubeka kokusebenza kokusebenza.

4. Thuthukisa i-Rheology yoketshezi lokumba
I-CMC inamanzi amahle we-solubility kanye nezindawo ezimbongini ze-rheological, ezingalungisa i-rheology yoketshezi lokumba ukuze ikwazi ukugcina ukusebenza okuzinzile ngaphansi kwezinga lokushisa eliphakeme kanye nezimo eziphakeme zokucindezela. I-Rheology enhle ayizuzi nje ekusakazweni koketshezi lokumba kanye nokuthwalwa kwama-cuttings, kepha futhi kuvimbela uketshezi lokudonsa kusuka ekushisweni nasekuvuselelekeni kwezindawo eziphakeme kakhulu.

5. Hlela ngezimo ezihlukile zokumba
Njengengxenye ye-polymer ezinzile, i-CMC ingazivumelanisa nezindlela ezahlukene zezindawo zokumba. Noma ngabe kungamanzi amasha, amanzi anosawoti, noma uketshezi lokushayela kwe-polymer, i-CMC ingasebenzisa umphumela omuhle wokulahlekelwa kokulahlekelwa kokulahleka. Lokhu kwenza i-CMC i-Fluid yokushayela eguquguqukayo kakhulu futhi isetshenziswa kabanzi kuzo zonke izinhlobo zemisebenzi yokumba.

6. Ukuvikelwa Kwezemvelo
I-CMC iyi-cellulose yemvelo etholwa nge-biodegradeality enhle nokuvikelwa kwemvelo. Uma kuqhathaniswa nothile olwenziwe ngamakhemikhali wamakhemikhali olahlekelwe yi-agents, i-CMC ibangela ukungcoliswa okuncane kwezemvelo futhi kuhambisana nezidingo zokuvikelwa kwemvelo zemisebenzi yesimanje yokumba.

7. Komnotho
Izindleko zokukhiqiza ze-CMC ziphansi, umphumela wokusebenzisa ubalulekile, futhi ukusebenza kwezindleko kuphezulu. Ngakho-ke, i-CMC ingukhetho lwezomnotho futhi olusebenzayo phakathi kokumba uketshezi lwe-fluid futhi luthandwa kabanzi imboni yokumba kawoyela.

I-Carboxymethyl Cellulose (CMC) isetshenziswa njengokulahlekelwa koketshezi okunciphisa uketshezi lokulawula ukulahlekelwa uketshezi, kuthuthukiswe ukubonwa koketshezi, kuvikeleke izindonga zomthombo, futhi kungokwemvelo. idlala indima ebalulekile. Ukusebenza kwalo okuphakeme kwenza kube yilungu elibalulekile lokumba izithasiselo uketshezi, ukuhlinzeka ngesiqinisekiso esinamandla sentuthuko ebushelelezi yokusebenza kokushayela kanye nokuqina kodonga kahle.
