CMC (sodium carboxymethyl cellulose) iyingxenye ebalulekile ye-polymer polymer edlala izindima ezahlukahlukene ezisemqoka zokumba olwandle, ikakhulukazi ekuhlelweni nasekusebenzeni kokusebenza koketshezi lokumba. Ukushayela okujulile kolwandle kuwukusebenza ngezidingo zobuchwepheshe eziphakeme kakhulu kanye nezimo ezinokhahlo kwezemvelo. Ngokuthuthukiswa kwezinsizakusebenza zika-Offshore uwoyela kanye negesi, isikali nokujula kokumba okujulile kolwandle kuyakhula kancane kancane. Njengesengezo samakhemikhali esisebenza kahle, i-CMC ingathuthukisa ukusebenza kahle, ukuphepha kanye nokuvikelwa kwemvelo kwenqubo yokumba.
1 Iqhaza elibalulekile ku-drive fluid
Ngesikhathi sokumba okujulile kolwandle, uketshezi oludonsa ludlala imisebenzi ebalulekile njengokusekela udonga kahle, ukupholisa i-drill bit, ukususa ama-chip, nokugcina ingcindezi yokwehla. I-CMC i-Regulator esebenzayo ye-Viscosity, i-ejenti ye-Rheological kanye nomkhulu, osetshenziswa kabanzi lapho kulungiswa uketshezi lokumba. Imisebenzi yayo eyinhloko ibonakala kulezi zinto ezilandelayo:
1.1 Ukuqina nokuguqula i-viscosity
Ekuvuthweni kolwandle okujulile, ngenxa yokwanda kokujula kwamanzi nengcindezi, uketshezi lokumba kufanele kube nokubonakala okuthile kokuqinisekisa ukuvela kwalo kanye nokuphatha umthamo. I-CMC ingaqina ngempumelelo uketshezi oludonsa futhi isize ukugcina ukuqina koketshezi lokudonsa ngokujula okuhlukile kanye nezingcindezi. Ngokushintsha okuhlushwa kwe-CMC, ukubonakala koketshezi lokumba kungalungiselelwe ukuqinisekisa ukuthi uketshezi oludonsayo lunezici ezifanele zokugeleza, ukuze ligeleze ngokukhululeka ezindaweni eziyinkimbinkimbi ezijulile futhi zivikele izinkinga ezinjengokwenziwa kahle.
1.2 Ukuthuthukisa Izakhiwo Ze-Rheological
Izakhiwo ze-Rheological zoketshezi lokumba zibalulekile ekuvutheni kolwandle okujulile. I-CMC ingathuthukisa uketshezi lokumba uketshezi, okwenza luphumelele ngokwengeziwe ngaphansi komhlaba, kunciphisa ukungqubuzana phakathi kwe-drill bit kanye nodonga lomthombo, ukunciphisa ukusetshenziswa kwamandla kanye nokwenza impilo yensiza yokumba imishini yokumba. Ngaphezu kwalokho, izakhiwo ezinhle zembongo zingaqinisekisa ukuthi uketshezi oludonsayo lungaphatha ngempumelelo ukusikwa nokuvimbela izinhlayiya eziqinile kuketshezi oluqinile, ngaleyo ndlela lugweme izinkinga ezinjenge-blockage.
2. Ukuqina kokuhle nokuvinjwa kokwakheka kwe-hydrate
Enqubweni yokumba okujulile kolwandle, ukuqina kwe-Wellbore kuyinkinga ebalulekile. Izindawo ezijulile zolwandle zivame ukubhekana nezimo eziyinkimbinkimbi zezwe, njengokucindezela okukhulu, izinga lokushisa eliphakeme, kanye nokubekwa kabusha kwe-sediment, okungaholela ekuwohlokeni komthombo noma ukudonsa uketshezi. I-CMC isiza ukuthuthukisa ukuqina kodonga lwe-Wellbore futhi ivikele ukuwa kahle kahle ngokwenza ngcono ukubonakala nezimbobo zesimbobo soketshezi lokumba.
Ekubizeni okujulile kolwandle, ukwakheka kwama-hydrate (anjenge-gesi yemvelo ama-hydrate) nakho kuyinkinga enganakwa. Ngaphansi kokushisa okuphansi kanye nezimo eziphakeme zokucindezela, ama-hydrate wemvelo akhiwa kalula ngesikhathi senqubo yokumba futhi abangele ukuvalwa koketshezi lokumba. Njenge-ejenti ye-hydration esebenza kahle, i-CMC ingavimbela ngempumelelo ukwakheka kwama-hydrate, gcina uketshezi loketshezi lokumba, futhi uqinisekise inqubekela phambili ebushelelezi yokusebenza.
3. Yehlisa umthelela wezemvelo
Ngezidingo ezivikelekile zemvelo ezisontayo, umthelela emvelweni ngesikhathi sokumba ohlala ulwandle usuthole ukunakwa okwengeziwe. Ukusetshenziswa kwe-CMC ekuvuthweni okujulile kolwandle kunganciphisa ngempumelelo ukuphuma kwezinto eziyingozi ku-drive fluid. Njengezinto zemvelo, i-CMC ine-biodegradadamability enhle kanye nobungane bezemvelo. Ukusetshenziswa kwayo kunganciphisa ubuthi boketshezi lokumba futhi kunciphise ukungcoliswa kwemvelo yasolwandle.
Ngaphezu kwalokho, i-CMC ingathuthukisa futhi isilinganiso sokuvuselelwa koketshezi lokumba. Ngokushintsha ngempumelelo ukusebenza koketshezi lokumba, kunciphisa ukulahlekelwa koketshezi lokumba, futhi kuqinisekiswe ukuthi uketshezi oludonsayo lungasetshenziswa kaninginingi, umthwalo endaweni yasolwandle ngesikhathi senqubo yokumba uyenziwa. Lokhu kubaluleke kakhulu ekuthuthukisweni okuqhubekayo kokumba okujulile kolwandle.
4. Thuthukisa ukusebenza kahle nokuphepha
Ukusetshenziswa kwe-CMC akugcini nje ngokuthuthukisa ukusebenza koketshezi olude olusolwandle, kepha futhi kuthuthukisa ukusebenza kahle kokudla kanye nokuphepha kokusebenza ngezinga elithile. Okokuqala, i-CMC ingenza uketshezi lokumba livumelane nezimo ezahlukahlukene zezwe, yehlisa umkhathi wepayipi elinamathele kanye nokuvinjwa ngesikhathi sokumba, futhi uqinisekise inqubekela phambili ebushelelezi yokusebenza. Okwesibili, ukusebenza okuzinzile okunamandla koketshezi kungathuthukisa ukunemba kokumba futhi kugweme ukwehluleka kokumba okubangelwa odongeni olungazenzile noma ezinye izinto. Ngaphezu kwalokho, i-CMC inganciphisa ngempumelelo ingozi yokushintshashintsha kwengcindezi ye-Domole Tschelbations, yehlisa izimo eziyingozi ezifana nokufafaza kanye nokufafaza kodaka okungenzeka ngesikhathi sokumba, futhi kuqinisekiswe ukuphepha kwemisebenzi.
I-5. Ukusebenza kwezindleko kanye nomnotho
Yize ukusetshenziswa kweCmUzokhuphula izindleko ezithile, lezi zindleko zilawulwa ngokuqhathaniswa ngokuqhathaniswa nokwenza ngcono ekusebenzeni kahle nasekuqiniseni kokuphepha kuletha. I-CMC ingathuthukisa ukuqina koketshezi lokumba futhi inciphise isidingo sezinye izithasiselo zamakhemikhali, ngaleyo ndlela kunciphise izindleko eziphelele zoketshezi lokumba. Ngasikhathi sinye, ukusetshenziswa kwe-CMC kunganciphisa ukulahleka kwemishini kanye nezindleko zokulungisa, ukuthuthukisa ukusebenza kahle kokukhiqiza kokusebenza kokumba, futhi ngaleyo ndlela kuletha izinzuzo zezomnotho eziphakeme.
Njengesengezo esisebenza kahle samakhemikhali, i-CMC idlala indima ebalulekile ekubizeni okujulile kolwandle. Akukwazi ukuthuthukisa ukusebenza koketshezi lokumba futhi kuthuthukise ukuqina komthombo, kepha futhi kuvimbela ngempumelelo ukwakheka kwama-hydrate, ukunciphisa ukungcoliswa kwemvelo, futhi kuthuthukise ukusebenza kahle nokuphepha. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokumba ohlala olwandle kanye nokwenza ngcono okuqhubekayo kwezidingo zokuvikelwa kwemvelo, ukusetshenziswa kwe-CMC kuzokhulisa kakhulu futhi kube ngolunye lwezinto ezibalulekile ezibalulekile ekuvuthweni kolwandle okujulile.
