Umxube wokuxuba i-bentonite ekubhobhozeni udaka unokuhluka ngokuxhomekeka kwiimfuno ezithile zokusebenza kokugaya kunye nohlobo lodaka olusetyenziswayo. I-Bentonite iyona nxalenye ephambili yodaka lokugaya, kwaye injongo yayo ephambili kukuphucula i-viscosity kunye ne-lubrication properties zodaka. Umlinganiselo ofanelekileyo wokuxuba ubalulekile ekufezekiseni ukusebenza kakuhle kodaka lokomba.
Ngokuqhelekileyo, i-bentonite ixutywe namanzi ukuze yenze i-slurry, kwaye i-mix ratio ibonakaliswe njengomlinganiselo we-bentonite (ngobunzima) bongezwa kumthamo othile wamanzi. Iimpawu ezinqwenelekayo zodaka lokugaya, ezifana ne-viscosity, amandla e-gel, kunye nokulawulwa kokucoca, kuchaphazela ukhetho lomxube wokuxuba.
Izinto ezininzi zichaphazela ukuzimisela komxube wokuxuba, kubandakanywa uhlobo lwe-bentonite esetyenzisiweyo (i-bentonite ye-sodium okanye i-calcium bentonite), iimeko zokugaya, kunye neemfuno ezithile zomsebenzi wokugaya. Ezi zinto kufuneka ziqwalaselwe ukuba zilungelelanise udaka lokomba kwiimpawu zejoloji zokubunjwa okugrunjwayo.
I-sodium bentonite luhlobo lwe-bentonite olusetyenziswa ngokuqhelekileyo ekuqhubeni ukwakhiwa kodaka. Umxube oqhelekileyo wokuxuba udongwe lwe-sodium bentonite yi-20 ukuya kwi-35 yeepounds zodongwe lwe-bentonite ngamalitha angama-100 amanzi. Nangona kunjalo, lo mlinganiselo unokuhlengahlengiswa ngokusekelwe kwiimfuno ezithile kunye neemeko zokomba.
I-calcium bentonite, ngakolunye uhlangothi, inokufuna umxube ohlukeneyo wokuxuba xa kuthelekiswa ne-sodium bentonite. Ukhetho phakathi kwe-sodium bentonite kunye ne-calcium bentonite kuxhomekeke kwizinto ezifana neempawu ezifunwayo zamanzi, i-salinity ye-drilling fluid, kunye neempawu ze-geological zokubunjwa.
Ukongeza kumlinganiselo womxube osisiseko, ukwakhiwa kodaka kunokuqulatha ezinye izongezo zokuphucula ukusebenza. Ezi zongezo zinokubandakanya iipolymers, ii-viscosifiers, ii-agent zokulawula ulwelo, kunye nee-agent zokulinganisa. Ukusebenzisana phakathi kwe-bentonite kunye nezi zongezo ziqwalaselwa ngokucokisekileyo ukufezekisa iipropati ezifunwayo ze-rheological kunye neempawu zodaka zokugaya.
Kubalulekile ukuba iingcali zokomba ziqhube uvavanyo zelabhoratri kunye nolingo lwasendle ukuze kunyuswe ulungelelwaniso lomxube kwimisebenzi ethile yokomba. Injongo yayikukudala udaka lokomba oluza kuthwala ngokufanelekileyo i-drill cuttings ukuya phezulu, ukubonelela ngozinzo kumngxuma wokutsala, kunye nokuhlangabezana neemfuno zokusingqongileyo kunye nolawulo lwesiza sokomba.
Umlinganiselo wokuxuba we-bentonite ekubhobhozeni udaka yiparameter ebalulekileyo eyahluka ngokusekelwe kwizinto ezifana nohlobo lwe-bentonite, iimeko zokugaya kunye neepropati ezifunekayo zodaka. Iingcali zoshishino lokwemba zivavanya ngononophelo ezi zinto ukuze zigqibe ngomlinganiselo ofanelekileyo wokuxuba womsebenzi othile wokomba, ukuqinisekisa ukuba iziphumo zokomba ezisebenzayo nezinempumelelo.
