I-Hydroxyethyl Cellulose (HEC) yipolymer enyibilikayo emanzini esetyenziswa ngokubanzi kwinkqubo yokomba yeoli. Iimpawu zayo ezikhethekileyo zomzimba kunye neekhemikhali zinika iingenelo ezininzi kulo mmandla.
1. Ukuphuculwa kweempawu ze-rheological
Iselulosi yeHydroxyethyl ineempawu ezintle zokujiya kwaye inokunyusa kakhulu i-viscosity yolwelo lokomba. Le propati ibaluleke kakhulu ngexesha lokugaya, njengoko i-high-viscosity drilling fluids inokumisa ngcono ukusika i-drill cuttings kwaye ithintele ukuba ifakwe phantsi kwequla okanye kudonga lombhobho, ngaloo ndlela iphucula ukusebenza kakuhle kunye nokhuseleko. Ukuziphatha kwe-pseudoplastic yezisombululo ze-HEC kubangela ukuba i-viscosity ephantsi kwizinga eliphezulu lokucheba (ezifana kufuphi ne-drill bit), okunciphisa ukukhuhla kunye namandla okupompa, kunye ne-viscosity ephezulu kumazinga aphantsi okucheba (njengakukufutshane nodonga lwe-wellbore), enceda Ukuthwala kunye nokumisa i-drill cuttings.
2. Iipropati zokufakelwa kwamanzi kunye nokugcinwa kwamanzi
I-Hydroxyethyl cellulose ineempawu ezibalaseleyo ze-hydration kwaye inokunyibilika ngokukhawuleza emanzini kwaye yenze isisombululo esifanayo. Lo msebenzi uququzelela ukulungiswa okukhawulezayo kunye nokulungelelaniswa kokwenziwa kolwelo lokomba kwisiza, ukwandisa ukuguquguquka kokusebenza. Ukongeza, i-HEC nayo ineempawu ezinamandla zokugcina amanzi, ezinokuthi zinciphise ukukhuphuka kwamanzi kunye nokulahlekelwa kwamanzi kwi-drilling fluids kunye nokugcina uzinzo kunye nokusebenza kakuhle kwe-drilling fluids. Ngokukodwa kwiqondo lokushisa eliphezulu kunye neendawo zoxinzelelo oluphezulu, iimpawu zayo zokugcina amanzi zibaluleke kakhulu.
3. Ulawulo lwesihluzi
Ngethuba lenkqubo yokugaya, ukulahlekelwa kwamanzi ombane wokubhobhoza kuyipharamitha ebalulekileyo. Ukulahleka kokucoca okugqithisileyo kuya kukhokelela ekwandeni kobunzima bekeyiki yodaka, okuya kukhokelela kwiingxaki ezifana nokungazinzi kodonga kunye nokuvuza kakuhle. Iselulosi yeHydroxyethyl inokunciphisa ngokufanelekileyo ilahleko yolwelo lokugrumba, yenze ikeyiki eshinyeneyo yokucoca, inciphise umngcipheko wokuvuza kunye nokuwa kodonga lwequla, kwaye iphucule uzinzo lodonga lwequla. Ukongeza, i-HEC inokugcina ukusebenza okuzinzileyo phantsi kwamaxabiso ahlukeneyo e-pH kunye neemeko zoxinaniso lwe-electrolyte kwaye iqhelane neemeko ezahlukeneyo zejoloji.
4. Eco-friendly
Njengoko imimiselo yokusingqongileyo iya isiba ngqongqo, imfuno yolwelo lokomba olulungele ukusingqongileyo nayo iyanda. Njengento ephuma kwiselulosi yendalo, i-hydroxyethyl cellulose inokonakala okuhle kwe-biodegradability kwaye inempembelelo encinci kokusingqongileyo. Xa kuthelekiswa nezinye iipolymers zokwenziwa, ukusetyenziswa kwe-HEC kunciphisa ukukhutshwa okuyingozi kwaye kunceda ukufezekisa iinjongo zokwemba okuluhlaza. Ukongeza, ubume obungeyotyhefu kunye nobungenabungozi be-HEC bukwanciphisa imingcipheko enokubakho kwimpilo yomsebenzisi.
5. Ezoqoqosho
Nangona ixabiso le-hydroxyethyl cellulose liphezulu kakhulu, ukusebenza kwayo okugqwesileyo ngexesha lokusetyenziswa kunokunciphisa kakhulu ixabiso elipheleleyo ngexesha lenkqubo yokomba. Okokuqala, ukuqina okusebenzayo kwe-HEC kunye nokugcinwa kwamanzi kwiipropathi zinciphisa ubungakanani bexabiso lokwemba kunye neendleko zempahla. Okwesibini, ukuzinza kunye nokuthembeka kwe-HEC kunciphisa umngcipheko wokungaphumeleli komhlaba kunye nokuvalwa okungacwangciswanga, ukunciphisa iindleko zokugcina nokulungiswa. Okokugqibela, iipropathi zeHEC ezihambelana nokusingqongileyo zinciphisa inkcitho yokulahlwa kwenkunkuma kunye nokuthotyelwa kokusingqongileyo.
6. Ukuhambelana kunye noKuguquguquka
I-Hydroxyethyl cellulose inozinzo oluhle lweekhemikhali kunye nokuhambelana okubanzi, kwaye inokuhambelana neentlobo ezahlukeneyo zezongezo kunye neenkqubo zokugaya ulwelo ukwenza inkqubo edibeneyo kunye nemisebenzi ethile. Ngokomzekelo, i-HEC ingasetyenziswa kunye ne-anti-collapse agents, i-anti-leak agents kunye ne-lubricant ukuphucula ukusebenza okubanzi kolwelo lokomba kunye nokuhlangabezana neemeko ezahlukeneyo zejoloji kunye neemfuno zokomba. Ukongeza, i-HEC ingasetyenziselwa kwezinye iikhemikhali ze-oilfield ezifana nokugqitywa kwamanzi kunye ne-fracturing fluids, ebonisa ukuguquguquka kwayo.
I-cellulose ye-Hydroxyethyl ineenzuzo eziphawulekayo kwi-oyile yokugaya, ibonakaliswe ngokukodwa ekuphuculeni iimpawu ze-rheological, ukwandisa i-hydration kunye nokugcinwa kwamanzi amandla, ukulawula ngokufanelekileyo umthamo wokucoca, ukuba nobuhlobo bendalo, uqoqosho kunye nemisebenzi emininzi. Ezi zibonelelo zenza i-HEC ibe yinto eyimfuneko kunye neyongezelelweyo ebalulekileyo kwinkqubo yokomba yeoli, inceda ukufezekisa imisebenzi yokwemba esebenzayo, ekhuselekileyo kunye nokusingqongileyo. Ngokuqhubela phambili okuqhubekayo kweteknoloji kunye nokujula kokusetyenziswa, amathuba okusetyenziswa kwe-hydroxyethyl cellulose kwi-oyile drilling iya kuba banzi.
