I-Carboxymethyl cellulose (CMC) iyi-polymer ephezulu yamangqamuzana esetshenziswa kabanzi ekubholeni uketshezi olunezici ezinhle ze-rheological nokuzinza. I-cellulose eguquliwe, ikakhulukazi eyakhiwe ngokusabela kwe-cellulose nge-chloroacetic acid. Ngenxa yokusebenza kwayo okuhle kakhulu, i-CMC isetshenziswe kabanzi emikhakheni eminingi efana nokumba uwoyela, izimayini, ukwakhiwa kanye nemboni yokudla.
1. Izakhiwo ze-CMC
I-Carboxymethyl cellulose iyimpushana emhlophe kuya kokuphuzi ekhanyayo eyenza isixazululo se-colloidal esisobala lapho sincibilika emanzini. Isakhiwo sayo samakhemikhali siqukethe amaqembu e-carboxymethyl, okwenza ibe ne-hydrophilicity enhle kanye nokuthambisa. Ngaphezu kwalokho, i-viscosity ye-CMC ingalawulwa ngokulungisa isisindo sayo samangqamuzana nokugxilisa ingqondo, okwenza ukusetshenziswa kwayo kumanzi okumba kuguquguquke kakhulu.
2. Iqhaza ekubhojweni okusamanzi
Ngesikhathi sokumba, ukusebenza koketshezi lokumba kubalulekile. I-CMC idlala izindima ezibalulekile ezilandelayo ekubhojweni okusamanzi:
I-Thickener: I-CMC ingakhuphula i-viscosity yoketshezi lokumba, ngaleyo ndlela ithuthukise umthamo wazo wokuthwala, igcine izinhlayiya eziqinile ezimisiwe, futhi ivimbele ukubola.
I-Rheology modifier: Ngokulungisa izici ze-rheological zoketshezi lokumba, i-CMC ingathuthukisa ukugeleza kwayo ukuze isakwazi ukugcina uketshezi oluhle ngaphansi kwezinga lokushisa eliphezulu nezimo zengcindezi ephezulu.
I-ejenti yokuxhuma: Izinhlayiya ze-CMC zingagcwalisa ukuqhekeka kwamadwala, zinciphise ngempumelelo ukulahlekelwa uketshezi futhi zithuthukise ukusebenza kahle kokumba.
I-Lubricant: Ukwengezwa kwe-CMC kunganciphisa ukungqubuzana phakathi kwe-drill bit nodonga lomthombo, kunciphise ukuguga futhi kukhuphule isivinini sokumba.
3. Izinzuzo ze-CMC
Ukusebenzisa i-carboxymethyl cellulose njengesengezo soketshezi lokumba kunezinzuzo ezilandelayo:
Ihambisana nemvelo: I-CMC iyimpahla ye-polymer yemvelo enokubola okuhle kanye nomthelela omncane emvelweni.
Ukusebenza kahle kwezindleko: Uma kuqhathaniswa namanye ama-polymer okwenziwa, i-CMC inezindleko eziphansi, ukusebenza okuhle kakhulu kanye nokusebenza kahle kwezindleko eziphezulu.
Izinga lokushisa nosawoti ovumelana nezimo: I-CMC isengagcina ukusebenza okuzinzile endaweni yokushisa ephezulu kanye nasezindaweni ezinosawoti ophakeme futhi ivumelane nezimo ezihlukahlukene zokuma komhlaba.
4. Izibonelo zohlelo lokusebenza
Ekusetshenzisweni kwangempela, izinkampani eziningi zikawoyela zisebenzise ngempumelelo i-CMC kumaphrojekthi ahlukene okumba. Isibonelo, kwezinye izinga lokushisa eliphezulu kanye nemithombo yokucindezela okuphezulu, ukwengeza inani elifanele le-CMC kungalawula ngokuphumelelayo i-rheology yodaka futhi kuqinisekise ukubhola okubushelelezi. Ngaphezu kwalokho, kwezinye izimo eziyinkimbinkimbi, ukusebenzisa i-CMC njenge-ejenti yokuxhuma kunganciphisa kakhulu ukulahlekelwa uketshezi futhi kuthuthukise ukusebenza kahle kokumba.
5. Izinyathelo zokuphepha
Yize i-CMC inezinzuzo eziningi, amaphuzu alandelayo kufanele aqashelwe ngesikhathi sokusetshenziswa:
Isilinganiso: Lungisa inani le-CMC elingezwe ngokwemibandela yangempela. Ukusebenzisa ngokweqile kungase kuholele ekuncipheni koketshezi.
Izimo zesitoreji: Kufanele igcinwe endaweni eyomile futhi epholile ukugwema umswakama ophazamisa ukusebenza.
Ukuxuba ngokulinganayo: Lapho ulungiselela uketshezi lokumba, qinisekisa ukuthi i-CMC incibilike ngokuphelele ukugwema ukuhlangana kwezinhlayiyana.
Ukusetshenziswa kwe-carboxymethyl cellulose oketshezini lokumba akuthuthukisi nje kuphela ukusebenza kahle kokumba futhi kunciphisa izindleko, kodwa futhi kuthuthukisa ukuthuthukiswa kobuchwepheshe bokuvikela imvelo ngezinga elithile. Ngokuthuthuka kwesayensi nobuchwepheshe, ububanzi bokufaka izicelo be-CMC buzonwetshwa futhi, futhi sibheke ngabomvu ukudlala indima enkulu kumaphrojekthi wokumba wesikhathi esizayo.
