I-Hydroxyethyl cellulose (HEC) i-polymer engeyona i-ionic emanzini enokujiya okuhle kakhulu, ukugcinwa kwamanzi, ukuzinza kanye nezakhiwo zokugcoba. Emaphrojekthini okumba uwoyela, ukusebenza koketshezi lokumba, uketshezi lokuphothula kanye noketshezi oluqhekekayo kudlala indima ebalulekile ekusebenzeni kahle kokubhola kanye nokuzinza kodonga lwemithombo. Njengesengezo esibalulekile sokumba uketshezi, i-HEC isetshenziswe kabanzi emkhakheni wokumba uwoyela.
Izici eziyisisekelo ze-hydroxyethyl cellulose
1. Ukuncibilika kwamanzi okuhle: I-HEC ingancibilika ngokushesha emanzini abandayo noma ashisayo ukuze yakhe isisombululo se-viscous esisobala, esilungele ukwakhiwa kwendawo.
2. Ikhono lokuguqula ukuqina kanye ne-rheological: I-HEC ingakhuphula ngokuphawulekayo i-viscosity kanye ne-thixotropy yoketshezi lokumba, ithuthukise umthamo othwala idwala loketshezi lokumba, isize ukuthwala ama-drill cuttings, futhi ithuthukise ukusebenza kahle kokumba.
3. Ukuzinza okuhle kakhulu kokuncibilika kukasawoti: I-HEC isengagcina ukunyibilika okuhle nokuzinza ngaphansi kwezimo eziphakeme zamaminerali, futhi ifanele ukubhola olwandle kanye nokwakheka kukasawoti omningi.
I-lubricity enhle: I-HEC inganciphisa i-coefficient yokungqubuzana koketshezi lokumba, inciphise ukuguga kwe-drill bit nodonga lomthombo, futhi yandise impilo yesevisi yemishini.
4. Ukumelana nezinga lokushisa nokugunda: I-HEC isengakwazi ukugcina i-viscosity ezinzile ngaphansi kwezimo eziphakeme zokushisa nezimo eziphakeme zokugunda, futhi ifanelekela indawo ejulile yomthombo kanye ne-ultra-deep well drilling.
Ukusetshenziswa kwe-hydroxyethyl cellulose ekubholeni uwoyela
1. I-drilling fluid thickener
Ngesikhathi sokumba, uketshezi lokumba lusetshenziselwa ukupholisa i-drill bit, ukugcoba ipayipi lokubhoboza, ukuthwala okusikiwe nokusimamisa udonga lomthombo. Umphumela wokujiya we-HEC ungakhuphula i-viscosity namandla okuthwala uketshezi lokumba, ukuze lukwazi ukumisa okwesikhashana futhi luthuthe izingcezu ezisikiwe, zivimbele ukuba zifakwe ngaphansi komthombo noma epayipini, futhi kuthinte ukusebenza kahle kokumba. Ukwengeza, ukusebenza kokuqina kwe-HEC nakho kungathuthukisa izici zokunciphisa i-shear yoketshezi lokumba futhi kuthuthukise ikhono lokuhlanza umthombo.
2. Uketshezi lokuphothula izithasiselo eziwuketshezi nokufaka usimende
Uketshezi lokuphothula lusetshenziselwa ukuvikela kanye nokusimamisa udonga lomthombo ukuze kuqinisekiswe inqubekelaphambili eshelelayo yokukhiqizwa kwamafutha negesi okulandelayo. I-HEC ingasetshenziswa njenge-thickener yokugcwalisa uketshezi ukuze inikeze i-viscosity efanele, ithuthukise ikhono lokumiswa, futhi ivimbele ukuwohloka kodonga oluhle. Ngesikhathi senqubo yokufaka usimende, ukunamathela okuhle kwe-HEC kusiza ukusabalalisa ngokulinganayo udaka lukasimende, ukuthuthukisa ikhwalithi kasimende, kuthuthukise ukuzinza kwezingqimba zikasimende, nokunciphisa ukuvuza koketshezi.
3. Isilungisi se-fracturing fluid
I-Hydraulic fracturing iyisilinganiso esivamile sokwandisa ukukhiqizwa nokujova. I-Fracturing fluid isetshenziselwa ukudala ukuphuka okwenziwe futhi kwandiswe ukungeneka kwemithombo kawoyela negesi. Njenge-thickener ye-fracturing fluid, i-HEC ingathuthukisa izakhiwo ze-rheological, ikhulise i-ductility kanye namandla okuthwala isihlabathi sokuphuka, futhi iqinisekise umphumela wokuphuka. Ukwengeza, ukuncibilika kwamanzi okuhle kwe-HEC kwenza kube lula ukuwohloka kalula enqubweni yokuphulwa kwejeli yakamuva ngaphandle kokudala umonakalo wokwakheka, okusiza ekuthuthukiseni umthamo wokukhiqiza wemithombo kawoyela negesi.
4. Isinciphisi sokulahlekelwa uketshezi
Ngesikhathi sokumba, ukulawulwa kokulahlekelwa uketshezi kubalulekile ukuze kuvinjwe ukungazinzi kwe-wellbore kanye nokwakheka kwamakhekhe odaka. I-HEC inganciphisa ngokuphumelelayo inani lokulahlekelwa uketshezi lokumba, inciphise ukungena koketshezi ekubunjweni, ivimbele ukuwa kwe-wellbore, futhi ithuthukise ukuphepha nokuzinza kwemisebenzi yokumba. Ikakhulukazi ekwakhekeni okuphezulu kokungena, umphumela wokulawula ukulahlekelwa uketshezi lwe-HEC ubaluleke kakhulu, osiza ekugcineni ubuqotho be-wellbore.
5. Ukufaka isicelo ekubhobozeni ogwini nasezindaweni ezinosawoti omningi
Ngesikhathi sokumba ogwini kanye nokubumba usawoti omningi, uketshezi lokumba ludinga ukukwazi ukumelana nosawoti kanye ne-calcium. I-HEC isengagcina ukuncibilika okuhle nokuzinza endaweni ene-mineralization ephezulu, engathuthukisa ngokuphumelelayo ukumelana nosawoti oketshezini lokumba futhi kuvimbele ukuhluleka koketshezi lokumba. Ngaphezu kwalokho, i-biodegradability ye-HEC iphinde iyenze ibe isithasiselo esikhethwayo soketshezi lokumba oluhambisana nemvelo.
I-Hydroxyethyl cellulose idlala indima ebalulekile emkhakheni wokumba uwoyela ngenxa yokuqina kwawo okuhle kakhulu, ukuncishiswa kokuhlunga, ukuthambisa kanye nokuzinza. Njengesengezo esiyinhloko soketshezi lokumba, uketshezi lokuqeda kanye noketshezi oluqhekekayo, i-HEC ingathuthukisa izakhiwo ze-rheological zoketshezi lokumba, inciphise ukuhlunga, ithuthukise amandla okuthwala amadwala, futhi ivumelane nezimo eziyinkimbinkimbi ezifana nosawoti ophezulu, izinga lokushisa eliphezulu kanye ne-shear ephezulu. Ekuthuthukisweni kwesikhathi esizayo kobuchwepheshe bokumba uwoyela, amathemba okufaka isicelo e-HEC azoba banzi, ikakhulukazi ocwaningweni nasekusetshenzisweni koketshezi lokumba oluluhlaza nolwemvelo, i-HEC kulindeleke ukuthi ibe yinto ebaluleke kakhulu yokusebenza.
