Iyini i-CMC kuDrilling Mud

I-Carboxymethyl cellulose (CMC) iyisengezo esivamile esisetshenziselwa ukumba ukwakhiwa kodaka embonini kawoyela negesi. Ukumba udaka, okwaziwa nangokuthi uketshezi lokumba, lwenza imisebenzi eminingana ebalulekile phakathi nenqubo yokumba, okuhlanganisa ukupholisa nokugcoba i-drill bit, ukuthwala ukusikwa kokubhoboza phezulu, ukugcina ukuzinza kwe-wellbore, nokuvimbela ukuqhunyiswa. I-CMC idlala indima ebalulekile ekufezeni lezi zinhloso ngezakhiwo nemisebenzi yayo ehlukahlukene ngaphakathi kodaka lokumba:

1. Ukulawulwa Kwe-Viscosity: I-CMC isebenza njengesilungisi se-rheology ekubholeni udaka ngokukhulisa i-viscosity yayo. Lokhu kusiza ukugcina izici zokugeleza ezifiselekayo zodaka, kuqinisekiswe ukuthi lithwala ngempumelelo i-drill cuttings phezulu futhi inikeza ukusekelwa okwanele ezindongeni zemithombo. Ukulawula i-viscosity kubalulekile ekuvimbeleni izinkinga ezinjengokulahlekelwa uketshezi, ukungazinzi kwe-wellbore, kanye nokunamathela okuhlukile.
2. Ukulawula Ukulahleka Kwe-Fluid: I-CMC yenza ikhekhe lesihlungi elincanyana, elingangeneki odongeni lomthombo, elisiza ukunciphisa ukulahlekelwa koketshezi ekubunjweni. Lokhu kubaluleke kakhulu ekuvimbeleni ukulimala kokwakheka, ukugcina ubuqotho bomthombo, kanye nokunciphisa ingozi yokulahleka kokujikeleza kwegazi, lapho udaka lokumba lubalekela ezindaweni ezikwazi ukungena kalula.
3. Ukumiswa Kwezinsimbi Zokubhoboza: I-CMC isiza ekumisweni kokusikwa kokubhola ngaphakathi kodaka lokumba, ivimbele ukuthi zingazinzi phansi phansi komthombo. Lokhu kuqinisekisa ukususwa okuphumelelayo kokusikwa okuvela emthonjeni futhi kusiza ukugcina ukusebenza kahle nokukhiqiza.
4. Ukuhlanza Imigodi: Ngokwandisa i-viscosity yodaka lokumba, i-CMC ithuthukisa umthamo wayo wokuthwala kanye nekhono lokuhlanza imigodi. Lokhu kusiza ekuqinisekiseni ukuthi ama-drill cuttings ahanjiswa ngempumelelo phezulu, avimbele ukuthi aqongelele phansi emgodini futhi avimbele ukuqhubeka kokumba.
5. Ukugcotshwa: I-CMC ingasebenza njengesithambisi ekumbiweni kodaka, inciphise ukungqubuzana phakathi kwentambo yokubhoboza nezindonga zomthombo. Lokhu kusiza ukunciphisa i-torque nokudonsa, ukuthuthukisa ukusebenza kahle kokumba, nokwelula impilo yemishini yokumba.
6. Ukuqina Kwezinga Lokushisa: I-CMC ikhombisa ukuzinza okuhle kwezinga lokushisa, igcina i-viscosity yayo nokusebenza ezinhlobonhlobo zezimo ze-downhole. Lokhu kuyenza ifanelekele ukusetshenziswa kokubili kokumba okuvamile kanye nezinga lokushisa eliphezulu.

I-CMC iyisengezo esishintshashintshashintshashintshayo esidlala indima ebalulekile ekwakhiweni kodaka lokumba, esiza ekwandiseni ukusebenza kokumba, ukugcina ukuqina kwe-wellbore, kanye nokuqinisekisa ukuphepha nokusebenza kahle kwemisebenzi yokumba embonini kawoyela negesi.
