I-CMC (Carboxymethyl Cellulose) iyisengezo samakhemikhali esisetshenziswa kakhulu embonini yokumba uwoyela, ikakhulukazi njenge-thickener ne-stabilizer yokumba uketshezi. Umthelela wawo ekusebenzeni kahle kokumba unezici eziningi futhi kungaxoxwa ngakho ngemibono yokuthuthukisa ukusebenza koketshezi lokumba, ukunciphisa izinkinga phakathi nenqubo yokumba, kanye nokwenza kahle inqubo yokumba.
1. Imisebenzi eyisisekelo ye-CMC
ukuqina umphumela
I-CMC ingakhuphula kakhulu i-viscosity yoketshezi lokumba. Lesi sakhiwo sibalulekile ekusebenzeni kokumba ngoba uketshezi lokumba olujiyile lunganikeza umthamo ongcono wokuthwala namandla okuthutha, lusize ukukhipha okusikiwe emthonjeni futhi kuvimbele ukubekwa kwazo. Ngesikhathi esifanayo, i-viscosity ephakeme isiza ukugcina ukumiswa okuhle ekwakhekeni okuyinkimbinkimbi futhi ivimbele ukusikwa ekuvaleni umthombo.
ukuzinza kwe-liquid
I-CMC inokuncibilika okuqinile kwamanzi kanye nezinga lokushisa elihle nokumelana nosawoti, okuyivumela ukuthi isebenze ngokuzinza ngaphansi kwezimo ezihlukene zokuma komhlaba. Ukuqina kwayo kwamakhemikhali okuhle kakhulu kanye nezakhiwo zokugcoba kunciphisa izinkinga ezihlukahlukene ezibangelwa ukungazinzi koketshezi lokumba ngesikhathi sokumba, njengemvula yodaka, ukuphunyuka kwegesi, njll.
Yehlisa ukulahlekelwa uketshezi lodaka olusekelwe emanzini
Ngokusebenzisana nezinye izakhi, i-CMC inganciphisa ngempumelelo ukulahleka kwesihlungi soketshezi lokumba, ngaleyo ndlela ivimbele amanzi ukuthi angangeni ungqimba olungaphansi komhlaba, inciphise umonakalo ekwakhekeni kwamadwala azungezile, ivikele udonga lomthombo, futhi ngaleyo ndlela ithuthukise ukusebenza kahle kokumba.
2. Umthelela othize we-CMC ekusebenzeni kahle kokumba
Thuthukisa ukusebenza kokuhlanza koketshezi lokumba
Phakathi nenqubo yokumba, ukungqubuzana phakathi kwe-drill bit kanye nokwakheka kuzokhiqiza inani elikhulu lokusika. Uma zingakwazi ukususwa ngesikhathi, kuzodala ukuphazamiseka ekusebenzeni kokumba. I-CMC ithuthukisa ukumiswa kanye namandla okuthwala uketshezi lokumba, olungakhipha lezi zicucu ngaphandle kwesihloko somthombo ukuze kuqinisekiswe ukuhlanzeka komthombo. Lo msebenzi ubaluleke kakhulu ezinhlotsheni zemithombo eyinkimbinkimbi njengemithombo ejulile, imithombo ejulile kakhulu, nemithombo evundlile. Ingagwema ngempumelelo izinkinga ezifana nokuvala kahle kwe-wellbore kanye nokunamathela kancane, ngaleyo ndlela kukhuphule isivinini sokumba.
Yehlisa ingozi yokuwa kweshaft
Kwezinye izinhlobo zamatshe athambile noma axegayo, omunye wemisebenzi eyinhloko yoketshezi lokumba ukugcina ukuzinza kodonga lomthombo. Njengokuqina, i-CMC ingenza ngcono ukunamathela koketshezi lokumba, ivumele uketshezi lokumba ukuthi lwenze ifilimu evikelayo odongeni lomthombo ukuze kuvinjwe udonga lomthombo ukuthi lungabhidliki noma udaka lungangeni ematsheni azungezile. Lokhu akugcini nje ukuthuthukisa ukuphepha kokusebenza kokumba, kodwa futhi kunciphisa isikhathi sokuphumula esibangelwa ukungazinzi kodonga lomthombo, ngaleyo ndlela kuthuthukisa ukusebenza kahle kokumba.
Yehlisa ukulahleka koketshezi lokumba
Phakathi nenqubo yokumba, uketshezi lokumba lungangena endaweni engaphansi komhlaba, ikakhulukazi ezindaweni lapho idwala line-porosity ephezulu noma ukuphuka. I-CMC ingalawula ngempumelelo ukulahlekelwa uketshezi loketshezi lokumba futhi inciphise ukulahlekelwa uketshezi lokumba kuma-pores kanye nokuphuka. Lokhu akusizi nje kuphela ukonga izindleko zoketshezi lokumba, kodwa futhi kuvimbela uketshezi lokumba ukuba lungalahleki ngokushesha futhi luthinte imisebenzi, ukuqinisekisa ukuthi uketshezi lokumba luyaqhubeka nokwenza imisebenzi yalo ngempumelelo.
Thuthukisa ukusebenza kahle kokumba futhi unciphise umjikelezo wokumba
Ngenxa yokuthi i-CMC ithuthukisa ukusebenza koketshezi lokumba, yenza kangcono ekuhlanzeni umthombo, ukusimamisa udonga lomthombo, nokuthwala izinqamuleli, ngaleyo ndlela inciphise izinkinga ezihlukahlukene okuhlangatshezwane nazo phakathi nenqubo yokumba futhi iqinisekise ukuthi umsebenzi wokumba ungashelela. nokwenza kahle. Ukuzinza nokuhlanza ukusebenza koketshezi lokumba kuthinta ngqo inqubekelaphambili yokumba. Ukusetshenziswa kwe-CMC kukhulisa isivinini sokumba, ngaleyo ndlela kufinyeze umjikelezo wokumba futhi kunciphisa izindleko zokusebenza zizonke.
3. Izibonelo zohlelo lokusebenza kanye nemiphumela esebenzayo ye-CMC
ukumba umthombo ojulile
Emgodini ojulile, njengoba ukujula kokumba kukhuphuka futhi ingcindezi ye-wellhead ikhula, ukuzinza nokumiswa koketshezi lokumba kubaluleke kakhulu. Ngokungeza i-CMC, i-viscosity yoketshezi lokumba ingathuthukiswa, amandla okuthwala ama-cuttings angathuthukiswa, futhi ukujikeleza okubushelelezi koketshezi lokumba kungaqinisekiswa. Ngaphezu kwalokho, i-CMC inganciphisa ngempumelelo ukumosha isikhathi okubangelwa ukubhidlika kodonga nokuvuza komthombo, ithuthukise ukusebenza kahle kokumba umthombo ojulile.
Ukushisa okuphezulu nokwakhiwa komfutho ophezulu wokumba
Ekwakhekeni okunamazinga okushisa aphezulu kanye nokucindezela okuphezulu, uketshezi lokumba ludinga ukuzinza okuphezulu kokushisa nokumelana nokucindezela. I-CMC ayikwazi nje ukwenza umphumela wokujiya ekushiseni okujwayelekile, kodwa futhi igcine ukuzinza okuhle ezindaweni zokushisa okuphezulu ukuze igweme ukucekelwa phansi kokusebenza koketshezi lokumba. Ekusetshenzisweni okungokoqobo, i-CMC inciphisa ukulahleka koketshezi lokumba ngesikhathi sokumba ngezindlela ezinjalo futhi inciphisa isikhathi sokuphumula esibangelwa izinkinga zoketshezi lokumba.
ukubhola ovundlile
Ngesikhathi sokumba imithombo evundlile, njengoba ukuzinza kodonga lomthombo kanye nokususwa kokusikwa kuyinkimbinkimbi ikakhulukazi, ukusetshenziswaI-CMC njenge-thickener inemiphumela ebalulekile. I-CMC ingathuthukisa ngempumelelo i-rheology yoketshezi lokumba, isize uketshezi lokumba lugcine ukumiswa okuhle namandla okuhamba, ukuze ukusikwa kukhishwe ngesikhathi, kugweme izinkinga ezinjengokubhajwa nokuvinjwa, kanye nokwenza ngcono ukusebenza kahle kokumba umthombo ovundlile.
Njengesengezo esisebenzayo sokumba uketshezi, ukusetshenziswa kwe-CMC ohlelweni lokumba kuthuthukisa kakhulu ukusebenza kahle kokumba. Ngokuthuthukisa i-viscosity, ukuzinza kanye nezakhiwo ze-rheological zoketshezi lokumba, i-CMC idlala indima ebalulekile ekuhlanzeni i-wellbore, ekwehliseni ukubhidlika kodonga lomthombo, ukulawula ukulahleka koketshezi, nokwandisa isivinini sokumba. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokumba, i-CMC inamathuba abanzi okusebenza ezindaweni ezihlukahlukene eziyinkimbinkimbi futhi izoqhubeka nokubamba iqhaza elibalulekile emisebenzini yokumba yesikhathi esizayo.
