Iyini indima ye-hydroxyethyl celtulose (HEC) ekuvuthayo kawoyela?

IHydroxYethylcellulose (HEC) idlala indima ebalulekile embonini yokumba kawoyela, ikakhulukazi ekudleni uketshezi noma udaka. Ukushayela uketshezi kubalulekile kwinqubo yokumba kahle kawoyela, ukuhlinzeka ngemisebenzi eminingi njengokupholisa nokuthambisa ukumba izingcezu, ukuthwala ukusikwa kokumba, nokugcina ukuqina komthombo. I-HEC isengezo esiyisihluthulelo kulamanzi wokumba, ukusiza ukuthuthukisa ukusebenza kwawo okuphelele nokusebenza.

Isingeniso se-Hydroxyethyl celtulose (HEC):

1. Isakhiwo samakhemikhali nezakhiwo:

I-Hydroxyyethyl celtulose iyi-nonional, i-polymer esoluniwe amanzi etholwe ukuguqulwa kwamakhemikhali kwe-cellulose.

Iqembu le-hydroxyethyl esakhiweni salo lisinikeza ukusondela emanzini kanye namafutha, okwenza liguquguquke.

Isisindo sayo samangqamuzana kanye nezinga lokufaka esikhundleni lithonya izakhiwo zalo ze-rhelogical, ezibaluleke kakhulu ekusebenzeni kwalo ku-drive fluid.

Ukuguqulwa kwe-2.Rheological:

I-HEC isetshenziswa njengesiguquli se-Rheology, okuthinta indlela yokugeleza kanye nokuvunywa koketshezi lokumba.

Ukulawulwa Kwezakhiwo Ze-Rheological kubalulekile ukwenza kahle ukusebenza koketshezi lokumba ngaphansi kwezimo ezahlukene zokwehla.

3. Ukulawulwa kokuhlunga:

I-HEC isebenza njenge-ejenti yokulawula i-Filtration, ivimbela ukulahlekelwa koketshezi ngokweqile ekwakhekeni.

I-polymer yakha ikhekhe elincanyana, elingenakufinyeleleka, elingenakufinyeleleka ku-Wellbore, linciphisa ukungenela uketshezi lwe-fluid ekwakhiweni kwamadwala azungezile.

4. Ukuhlanza nokulengiswa:

I-HEC isiza okwesikhashana ukusikwa kokumba, ukubavimbela ekuxazululeni ezansi komthombo.

Lokhu kuqinisekisa ukuhlanza okusebenzayo kwe-Wellbore, kugcina i-Wellbore icacile futhi ivimbela ama-blockages angaphazamisa inqubo yokumba.

I-5. Ukuthambisa nokupholisa:

Izakhiwo zokugcoba zosizo lwe-HEC zinciphisa ukungqubuzana phakathi kwentambo ye-drill kanye ne-Wellbore, ngaleyo ndlela kunciphise ukugqoka nokudabula imishini yokumba.

Kuyasiza futhi ukuqeda ukushisa, ukusiza ekupholiseni kokubika kancane ngesikhathi sokumba.

I-6. Ukuqina kokwakheka:

UHek uthuthukisa ukuqina kahle ngokunciphisa ubungozi bomonakalo wokwakha.

Kuyasiza ukugcina ubuqotho be-Wellbore ngokuvimbela ukuwa noma ukuwa kwefomu lamatshe azungezile.

7. Uketshezi olususelwa kumanzi

I-HEC isetshenziswa kakhulu kumanzi wokumba osuselwa emanzini ukuze udlulisele ukubonakala nokuqina koketshezi lokumba.

Ukuhambisana kwalo ngamanzi kwenza kulungele ukwakhela uketshezi lokumba olunobungane bemvelo.

8. Ukucindezela uketshezi lokushayela:

Kumanzi wokugaya okuvinjelitory, i-HEC idlala indima ekulawuleni i-shale hydration, ukuvikela ukwanda, kanye nokwenza ngcono ukuqina komthombo.

9. Imvelo ephezulu yokushisa:

I-HEC iyazinza kahle futhi ilungele ukusetshenziswa ekusebenzeni kokushisa okushisa kakhulu.

Izakhiwo zalo zibalulekile ekugcineni ukusebenza koketshezi lokumba ngaphansi kwezimo eziphakeme zokushisa.

10. Ukuvumelana okungeziwe:

I-HEC ingasetshenziswa ngokuhlanganiswa nezinye izithasiselo ezibandayo ezifana nama-polymers, ama-surfactants kanye nama-ejenti wokunciphisa ukufezekisa izakhiwo ezifiselekayo ze-fluid.

11. Shear Deckadation:

I-Shear ahlangane ngesikhathi sokumba ingadala ukwehlazeka, okuthinta izakhiwo zayo ze-rhelogical ngokuhamba kwesikhathi.

Ukwakhiwa kwesengezo okufanele nokukhethwa kwemali kunganciphisa izinselelo ezihlobene ne-shear.

12. Umthelela Wezemvelo:

Ngenkathi i-HEC icatshangelwa ngokuvamile imvelo, umthelela wezemvelo ophelele wokushayela uketshezi, kubandakanya ne-HEC, yisihloko sokukhathazeka okuqhubekayo nocwaningo.

13. Ukucatshangelwa Kwezindleko:

Ukusebenza kwezindleko zokusebenzisa i-HEC ku-dring fluids kucatshangelwa, ngabasebenza enesisindo sezinzuzo zesengezo ngokumelene nezindleko.

Ekuphetheni:

Ngamafuphi, i-Hydroxyyethyl celtulose iyisengezo esibalulekile embonini yokumba kawoyela, ifaka isandla empumelelweni ephelele kanye nokusebenza kahle kokusebenza kwemisebenzi. Imisebenzi yayo eminingi, kufaka phakathi ukuguqulwa kwe-Rheology, ukulawulwa kwe-Filtration, ukuhlanza umgodi nokuthambisa, kwenze kube yingxenye ehlanganisiwe yoketshezi lokumba. Njengoba ukudlala imisebenzi iyaqhubeka nokuvela futhi imboni ibhekene nezinselelo ezintsha kanye nokucatshangelwa kwemvelo, i-hec iyaqhubeka nokudlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kanye nokusimama kwemisebenzi yokumba kawoyela. Ukucwaninga okuqhubekayo kanye nentuthuko ku-polymer chemistry kanye ne-drive fluid Technology kungasiza ekuthuthukisweni nasekuthuthukisweni ekusebenziseni i-hydroxyethyl cellulose embonini kawoyela negesi.
