IHydroxyethyl Cellulose (HEC) iyi-polymer encibilika emanzini esetshenziswa kabanzi enqubweni yokumba uwoyela. Izakhiwo zayo eziyingqayizivele zomzimba namakhemikhali ziyinika izinzuzo eziningi kulo mkhakha.
1. Ukuthuthukiswa kwezakhiwo ze-rheological
I-Hydroxyethyl cellulose inezici ezinhle zokujiya futhi ingakhuphula kakhulu i-viscosity yoketshezi lokumba. Lesi sakhiwo sibaluleke kakhulu ngesikhathi sokumba, njengoba uketshezi lokumba olune-viscosity ephezulu lukwazi ukumisa kangcono ukusika ama-drill futhi luvimbele ukuthi lungafakwa ngaphansi komthombo noma odongeni lwamapayipi, ngaleyo ndlela kuthuthukiswe ukusebenza kahle nokuvikeleka kokubhola. Ukuziphatha kwe-pseudoplastic kwezixazululo ze-HEC kubangela i-viscosity ephansi emazingeni aphezulu okugunda (njengaseduze ne-drill bit), okunciphisa ukungqubuzana namandla okupompa, kanye ne-viscosity ephakeme ngamanani aphansi okugunda (njengaseduze kodonga lomthombo), okusiza Ukuthwala nokumisa ama-drill cuttings.
2. Izakhiwo zokufaka amanzi kanye nokugcinwa kwamanzi
I-Hydroxyethyl cellulose inezinto ezinhle kakhulu zokufaka amanzi futhi ingancibilika ngokushesha emanzini futhi yakhe isisombululo esifanayo. Lokhu kusebenza kusiza ukulungiselela ngokushesha kanye nokulungiswa kokwakheka koketshezi lokumba esizeni, okwandisa ukuguquguquka kokusebenza. Ngaphezu kwalokho, i-HEC iphinde ibe nezindawo eziqinile zokugcina amanzi, ezinganciphisa ukuhwamuka nokulahlekelwa kwamanzi emanzini okumba futhi igcine ukuzinza nokusebenza kahle koketshezi lokumba. Ikakhulukazi ekushiseni okuphezulu nasezindaweni ezicindezelayo, izindawo zayo zokugcina amanzi zibaluleke kakhulu.
3. Ukulawula isihlungi
Phakathi nenqubo yokumba, ukulahlekelwa kwamanzi oketshezi lokumba kuyipharamitha ebalulekile. Ukulahlekelwa kokuhlunga ngokweqile kuzoholela ekwandeni kokuqina kwekhekhe lodaka, okuzoholela ezinkingeni ezifana nokungaqini kahle kodonga kanye nokuvuza komthombo. I-Hydroxyethyl cellulose inganciphisa ngempumelelo uketshezi oluphumayo lokumba uketshezi, yakhe ikhekhe lokuhlunga eliminyene, inciphise ingozi yokuvuza nokuwa kodonga lomthombo, futhi ithuthukise ukuzinza kodonga lomthombo. Ngaphezu kwalokho, i-HEC ingagcina ukusebenza okuzinzile ngaphansi kwamanani e-pH ahlukene kanye nezimo zokuhlushwa kwe-electrolyte futhi ivumelane nezimo ezihlukahlukene ze-geological eziyinkimbinkimbi.
4. Eco-friendly
Njengoba imithetho yezemvelo iya ngokuya iqina, nesidingo sokumba izinto eziwuketshezi ezivikela imvelo siyakhula. Njengento ephuma ku-cellulose yemvelo, i-hydroxyethyl cellulose inokubola okuhle kwe-biodegradability futhi inomthelela omncane emvelweni. Uma kuqhathaniswa namanye ama-polymers okwenziwa, ukusetshenziswa kwe-HEC kunciphisa ukukhishwa okuyingozi futhi kusiza ukufeza imigomo yokumba eluhlaza. Ngaphezu kwalokho, imvelo engeyona enobuthi nengenabungozi ye-HEC iphinde yehlise izingozi ezingaba khona empilweni yabasebenzisi.
5. Ezomnotho
Nakuba intengo ye-hydroxyethyl cellulose iphezulu uma kuqhathaniswa, ukusebenza kwayo okuhle kakhulu ngesikhathi sokusetshenziswa kunganciphisa kakhulu izindleko zizonke phakathi nenqubo yokumba. Okokuqala, ukujiya okuphumelelayo kwe-HEC nokugcina amanzi kunciphisa inani loketshezi lokumba kanye nezindleko zempahla. Okwesibili, ukuzinza nokuthembeka kwe-HEC kunciphisa ingozi yokwehluleka okungaphansi komhlaba kanye nokuvalwa okungahleliwe, ukunciphisa izindleko zokulungisa nokulungisa. Okokugcina, izakhiwo ze-HEC ezihambisana nemvelo zinciphisa izindleko zokulahlwa kwemfucuza kanye nokuhambisana nemvelo.
6. Ukuvumelana kanye Nokuhlukahluka
I-Hydroxyethyl cellulose inokusimama okuhle kwamakhemikhali nokuhambisana okubanzi, futhi ingahambisana nezinhlobonhlobo zezithasiselo kanye nezinhlelo zoketshezi zokumba ukuze zakhe uhlelo oluyinhlanganisela olunemisebenzi ethile. Isibonelo, i-HEC ingasetshenziswa kanye nama-anti-collapse agents, ama-anti-leak agents kanye nezinto zokugcoba ukuze kuthuthukiswe ukusebenza okuphelele koketshezi lokumba kanye nokuhlangabezana nezimo ze-geological ezehlukene kanye nezidingo zokumba. Ukwengeza, i-HEC ingasetshenziswa nakwamanye amakhemikhali e-oilfield afana noketshezi lokuqeda kanye noketshezi oluqhekekayo, okubonisa ukuguquguquka kwayo.
I-Hydroxyethyl cellulose inezinzuzo eziphawulekayo ekumbaleni uwoyela, ikakhulukazi kuboniswa ekuthuthukiseni izakhiwo ze-rheological, ukwandisa umthamo we-hydration nokugcinwa kwamanzi, ukulawula ngokuphumelelayo umthamo wokuhlunga, ukuba nobungane bemvelo, ukonga nokusebenza okuningi. Lezi zinzuzo zenza i-HEC ibe isithasiselo esibalulekile nesibalulekile enqubweni yokumba uwoyela, esiza ukufeza imisebenzi yokumba ephumelelayo, ephephile futhi ehambisana nemvelo. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokujula kokusetshenziswa, amathuba okusetshenziswa kwe-hydroxyethyl cellulose ekumbaleni uwoyela azoba banzi.
