I-Polyanionic Cellulose oildrilling

I-Polyanionic cellulose (PAC) iyisengezo esibalulekile oketshezini lokumba uwoyela, esebenza imisebenzi ehlukahlukene ukuze kuthuthukiswe imisebenzi yokumba.Nansi indlela i-PAC enikela ngayo oketshezini lokumba uwoyela:

1. I-Viscosity Control: I-PAC isiza ukulawula i-viscosity yoketshezi lokumba, iqinisekise ukuthi inogqinsi oludingekayo ukuze ithwale kahle ama-cuttings abhoboziwe phezulu.Lokhu kubalulekile ukuze kugcinwe ukuzinza kwe-wellbore kanye nokuvimbela izinkinga ezinjengokugoqeka kwemigodi.
2. Ukuvimbela Ukulahleka Kwe-Fluid: I-PAC yenza ikhekhe lesihlungi elincanyana, elingangeneki odongeni lwe-borehole, linciphisa ukulahlekelwa uketshezi endaweni ezungezile.Ngokunciphisa ukulahlekelwa uketshezi, i-PAC isiza ukugcina ingcindezi ye-hydrostatic, ivimbele ukulimala kokwakheka, futhi ithuthukise ukukhiqiza kahle.
3. Ukuguqulwa Kwe-Rheology: I-PAC ithonya ukuziphatha kokugeleza kanye nezakhiwo ze-rheological zoketshezi lokumba, ithuthukisa ukumiswa kwezinto eziqinile futhi inciphise ukuzinza.Lokhu kuqinisekisa ukusebenza okungaguquguquki koketshezi lokumba ngaphansi kwezimo ezihlukene zemigodi.
4. Ukugcotshwa Nokuncishiswa Kwefriction: I-PAC inikeza ukuthambisa phakathi kwentambo yokubhoboza nodonga lomthombo, inciphisa ukungqubuzana futhi inciphise ukuhudula.Lokhu kusiza ukuthuthukisa ukusebenza kahle kokubhola, ukunciphisa ukuguga emishinini yokumba, nokwelula impilo yemishini.
5. Ukuhlanzeka Kwemigodi Okuthuthukisiwe: Ngokwandisa i-viscosity namandla okuthwala oketshezi lokumba, i-PAC isiza ukususwa kwezinsalela ezibhoboziwe kanye nemfucumfucu emthonjeni, ukuthuthukisa ukusebenza kahle kokuhlanza imigodi nokunciphisa ingozi yamapayipi abhajwe.
6. Izinga Lokushisa Nokuqina Kosawoti: I-PAC ibonisa ukubekezelela ukushisa okuphezulu nosawoti, igcina i-viscosity yayo nezici zokusebenza phezu kwebanga elibanzi lamazinga okushisa kanye nosawoti otholwa emisebenzini yokumba.
7. Inobungani Nemvelo: I-PAC isuselwa emithonjeni evuselelekayo esekwe ezitshalweni futhi iyakwazi ukubola, okuyenza ivumelane nemvelo futhi ifanelekele ukusetshenziswa ezindaweni zokumba ezizwelayo emvelweni.

Kafushane, i-polyanionic cellulose iyingxenye ebalulekile yoketshezi lokumba uwoyela, ihlinzeka nge-viscosification, ukulawulwa kokulahlekelwa uketshezi, ukuguqulwa kwe-rheology, nezinye izakhiwo ezibalulekile ukuze kuqinisekiswe ukusebenza kahle nokuphumelelayo kokumba embonini kawoyela negesi.Ukuthembeka kwayo, ukusebenza, nokuhambisana kwemvelo kuyenza ibe yinketho ekhethwayo yokuthuthukisa ukusebenza koketshezi lokumba kanye nokuzinza kwe-wellbore.
