Ithini indima ye-hydroxyethyl cellulose (HEC) ekwembeni ioyile?

IHydroxyethylcellulose (HEC) idlala indima ebalulekileyo kwishishini lokomba ioyile, 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 kubalulekile 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 ukukhupha 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 kukuqwalaselwa, 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.
