Hydroxyethyl Cellulose (HEC) igira uruhare runini mubikorwa bya peteroli na gaze. Nkibikoresho byinshi bya polymer, bikoreshwa cyane mugucukura amazi, kurangiza amazi, kuvunika amazi nindi mirima. Gukoresha no gukoresha bigaragarira cyane cyane mubice bikurikira:
1. Gukoresha amazi yo gucukura
a. Thickener
Ikoreshwa cyane rya HEC mugucukura amazi ni nkibyimbye. Amazi yo gucukura (icyondo) agomba kuba afite ubwiza runaka kugirango harebwe ko ibice byimyitozo bitwarwa hejuru mugihe cyo gucukura kugirango birinde gufunga iriba. HEC irashobora kongera cyane ubwiza bwamazi yo gucukura, ikayaha guhagarikwa neza no gutwara ubushobozi.
b. Umukozi wo kubaka urukuta
Mugihe cyo gucukura, guhagarara kurukuta ni ngombwa. HEC irashobora kunoza imikorere yo gucomeka amazi yo gucukura no gukora igipande cyinshi cya cake yicyondo kurukuta rwiriba kugirango irinde urukuta gusenyuka cyangwa gutemba neza. Izi ngaruka zo kubaka urukuta ntizitezimbere gusa kurukuta rwiriba, ahubwo runagabanya igihombo cyamazi yo gucukura, bityo bizamura imikorere yo gucukura.
c. Guhindura imvugo
HEC ifite imiterere myiza ya rheologiya kandi irashobora guhindura imiterere ya rheologiya ya dring fluid. Muguhindura ubunini bwa HEC, agaciro k'umusaruro hamwe n'ubukonje bwamazi yo gucukura birashobora kugenzurwa, bikaba ingenzi mubikorwa byo gucukura neza.
2. Gukoresha amazi yuzuye
a. Nibyiza kugenzura urukuta
Amazi yuzuye ni amazi akoreshwa mugusoza ibikorwa byo gucukura no gutegura umusaruro. Nkibice byingenzi mumazi yuzuye, HEC irashobora kugenzura neza ituze ryurukuta. Umubyimba wa HEC ubifasha gukora imiterere ihamye yo mumazi yuzuye, bityo igatanga inkunga nziza.
b. Igenzura ryemewe
Mugihe cyo kurangiza neza iriba, HEC irashobora gukora cake yuzuye ibyondo irinda amazi kwinjira. Iyi mikorere ni ingenzi cyane kugirango wirinde kwangirika kwangirika no kumeneka neza, kandi itume iterambere ryimbere ryibikorwa birangira.
c. Kugenzura igihombo
Mugukora cake nziza, HEC irashobora kugabanya gutakaza amazi kandi ikanakoresha neza amazi yuzuye. Ibi bifasha kugabanya ibiciro byo gukora kandi bikubaka neza.
3. Gukoresha amazi yamenetse
a. Thickener
Mubikorwa byo kuvunika hydraulic, amazi yamenetse akenera gutwara proppant (nkumucanga) mumeneka yimiterere kugirango ashyigikire imvune kandi imiyoboro ya peteroli na gaze ikingure. Nkibyimbye, HEC irashobora kongera ubwiza bwamazi yamenetse kandi ikongerera ubushobozi bwo gutwara umucanga, bityo bikagira ingaruka kumeneka.
b. Umukozi uhuza
HEC irashobora kandi gukoreshwa nkumukozi uhuza ibice kugirango habeho sisitemu ya gel ifite ubukonje bwinshi nimbaraga zinyuze mubitekerezo hamwe nindi miti. Sisitemu ya gel irashobora kunoza ubushobozi bwo gutwara umucanga bwamazi yamenetse kandi igakomeza guhagarara neza mubushyuhe bwinshi.
c. Umukozi ushinzwe kugenzura impamyabumenyi
Igikorwa cyo kuvunika kirangiye, ibisigara mumazi yamenetse bigomba kuvaho kugirango bigarure uburyo busanzwe bwo gushingwa. HEC irashobora kugenzura inzira yo kwangirika kugirango igabanye amazi yamenetse mumazi make-viscosity mugihe runaka kugirango ikurweho byoroshye.
4. Kurengera ibidukikije no kuramba
Nkibikoresho byamazi ya polymer yamashanyarazi, HEC ifite ibinyabuzima byiza kandi bihuza ibidukikije. Ugereranije n’ibikomoka kuri peteroli gakondo, HEC ntigira ingaruka nke ku bidukikije kandi ijyanye n’ibidukikije ndetse n’ibisabwa birambye by’ibikorwa bya peteroli na gaze bigezweho.
Ikoreshwa ryinshi rya hydroxyethyl selulose mubikorwa bya peteroli na gaze biterwa ahanini no kubyimba kwiza, kubaka urukuta, guhindura imvugo nibindi bikorwa. Ntabwo itezimbere gusa imikorere yo gucukura no kurangiza, inagira uruhare runini mukuvunika amazi, kunoza imikorere numutekano. Hamwe nogutezimbere ibisabwa byo kurengera ibidukikije, HEC, nkibikoresho byangiza ibidukikije, ifite ibyifuzo byinshi byo gusaba.
