IHydroxyethylcellulose (HEC) idlala indima ebalulekileyo kwishishini lokomba i-oyile, ngakumbi kulwelo lokomba okanye udaka. Ulwelo lokwemba lubalulekile kwinkqubo yokomba we-oyile, lubonelela ngemisebenzi emininzi efana nokupholisa kunye nokuthambisa amasuntswana e-drill, ukuthwala ukusika ukugrumba phezulu, kunye nokugcina uzinzo kwiqula. I-HEC yongezelela ephambili kule mibhobho yokomba, inceda ekuphuculeni ukusebenza kwabo ngokubanzi kunye nokusebenza.
Intshayelelo ngeHydroxyethyl Cellulose (HEC):
1. Ubume bekhemikhali kunye neempawu:
I-Hydroxyethyl cellulose i-nonionic, i-polymer e-soluble yamanzi efunyenwe ngokuguqulwa kweekhemikhali ze-cellulose.
Iqela le-hydroxyethyl kwisakhiwo salo linika ukunyibilika emanzini kunye ne-oyile, okwenza kube yinto eguquguqukayo.
Ubunzima bayo bemolekyuli kunye neqondo lokutshintshwa kunempembelelo kwiimpawu zayo ze-rheological, ezibaluleke kakhulu ekusebenzeni kwayo kumanzi okomba.
2.Ukuguqulwa kweRheological:
I-HEC isetyenziswe njenge-rheology modifier, echaphazela ukuziphatha kokuhamba kunye ne-viscosity ye-drilling fluids.
Ukulawulwa kweempawu ze-rheological kubaluleke kakhulu ekuphuculeni ukusebenza kwe-drilling fluids phantsi kweemeko ezahlukeneyo ze-downhole.
3. Ulawulo lwesihluzi:
I-HEC isebenza njenge-ejenti yokulawula ukuhluza, ukukhusela ukulahlekelwa kwamanzi amaninzi ekubunjweni.
Ipolima yenza ikeyiki ecekethekileyo, engangenekiyo yokucoca emthonjeni, inciphisa ukungena kolwelo lokugrumba kulwakhiwo olujikelezileyo.
4. Ukucoca kunye nokuxhoma:
I-HEC inceda ukumisa i-drill cuttings, ithintele ukuba ihlale phantsi kwequla.
Oku kuqinisekisa ukucocwa kwequla elisebenzayo, kugcina umthombo ucacile kwaye kuthintele imiqobo enokuthintela inkqubo yokomba.
5. Ukuthambisa kunye nokupholisa:
Iipropathi zokuthambisa ze-HEC zinceda ekunciphiseni ukungqubana phakathi komtya wokugrumba kunye ne-wellbore, ngaloo ndlela kuncitshiswa ukuguga kunye nokukrazula kwizixhobo zokomba.
Kwakhona kunceda ukutshabalalisa ubushushu, ukuncedisa ekupholiseni i-drill bit ngexesha lemisebenzi yokomba.
6. Uzinzo lokuqulunqa:
I-HEC iphucula uzinzo lwe-wellbore ngokunciphisa umngcipheko womonakalo wokwakheka.
Inceda ukugcina imfezeko yequla ngokunqanda ukuwa okanye ukudilika kokwakheka kwamatye ajikelezileyo.
7. Ulwelo lokomba olusekelwe emanzini:
I-HEC isetyenziswa ngokuqhelekileyo kwi-drilling fluids esekelwe emanzini ukunika i-viscosity kunye nokuzinza kwi-drilling fluid.
Ukuhambelana kwayo namanzi kuyenza ilungele ukuqulunqa ulwelo lokomba oluhambelana nokusingqongileyo.
8. Cindezela ulwelo lokomba:
Kwi-inhibitory drilling fluids, i-HEC idlala indima ekulawuleni i-shale hydration, ukuthintela ukwanda, kunye nokuphucula ukuzinza kwe-wellbore.
9. Indawo yobushushu obuphezulu:
I-HEC izinzile ngokwe-thermal kwaye ifanelekile ukuba isetyenziswe kwimisebenzi yokomba yobushushu obuphezulu.
Iimpawu zayo zibaluleke kakhulu ekugcineni ukusebenza kakuhle kwe-drilling fluids phantsi kweemeko eziphezulu zokushisa.
10. Ukuhambelana okongeziweyo:
I-HEC ingasetyenziswa ngokudityaniswa nezinye izongezo zolwelo zokomba ezifana neepolima, ii-surfactants kunye nee-agent zokulinganisa ukuphumeza iipropathi ezinqwenelekayo zolwelo.
11. Ukuchetywa kwesidima:
I-Shear edibene nayo ngexesha lokugaya inokubangela ukuba i-HEC ithobe, ichaphazela iimpawu zayo ze-rheological ngokuhamba kwexesha.
Ukuqulunqwa okufanelekileyo okongeziweyo kunye nokukhetha kunokunciphisa imingeni enxulumene nokucheba.
12. Impembelelo yokusingqongileyo:
Nangona i-HEC ngokuqhelekileyo ithathwa njengobungane bendalo, impembelelo yendalo yonke ye-drilling fluids, kubandakanywa ne-HEC, sisihloko senkxalabo eqhubekayo kunye nophando.
13. Ukuqwalaselwa kweendleko:
Ukusebenza kweendleko zokusebenzisa i-HEC kwi-drilling fluids kuqwalaselwa, kunye nabaqhubi abalinganisa iinzuzo zesongezo ngokuchasene neendleko.
ukuququmbela:
Isishwankathelo, i-hydroxyethyl cellulose yongezelelo oluxabisekileyo kwishishini le-oyile yokomba, igalelo kwimpumelelo yonke kunye nokusebenza kakuhle kokomba. Imisebenzi yayo emininzi, kubandakanywa ukuguqulwa kwe-rheology, ukulawulwa kokucoca, ukucocwa komngxuma kunye nokuthambisa, kuyenza ibe yinxalenye ebalulekileyo ye-drilling fluids. Njengoko imisebenzi yokumba iqhubeka nokuguquka kwaye ishishini lijongene nemingeni emitsha kunye nokuqwalaselwa kokusingqongileyo, i-HEC iyaqhubeka idlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kunye nokuzinza kwemisebenzi yokugaya ioli. Uphando oluqhubekayo kunye nophuhliso kwi-polymer chemistry kunye neteknoloji yokwemba ulwelo lunokuba negalelo kwinkqubela phambili kunye nokuphuculwa kokusetyenziswa kwe-hydroxyethyl cellulose kwishishini leoli negesi.
