Hydroxyethylcellulose (HEC) ni polymer idasanzwe, amazi ashonga ya polymer ikomoka kuri selile ikoresheje urukurikirane rw'imiti. Ikoreshwa cyane mu nganda zitandukanye, harimo n’inganda za peteroli na gaze, igira uruhare runini mu gucukura no kurangiza amazi. Ni muri urwo rwego, HEC ikora nk'impinduka ya rheologiya, igenzura imigezi, hamwe na tackifier, ifasha kuzamura imikorere muri rusange no gutsinda kw'ibikorwa bya peteroli.
1.Iriburiro rya Hydroxyethyl Cellulose (HEC)
Hydroxyethylcellulose ikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima. Kwinjiza amatsinda ya hydroxyethyl binyuze mumihindagurikire yimiti byongera imbaraga zamazi, bigatuma iba ibice byinshi bikwiranye nibikorwa bitandukanye. Mu nganda za peteroli na gaze, HEC ihabwa agaciro kubera imiterere ya rheologiya, itajegajega, hamwe n’ibindi byongerwaho bikoreshwa mu gucukura amazi.
2. Imikorere ya HEC ijyanye no gusaba peteroli
2.1. Amazi meza
Amazi meza ya HEC nikintu cyingenzi kiranga peteroli ikoreshwa. Amazi ya polymer yamashanyarazi yoroha kuvanga nibindi bikoresho byo gucukura kandi bikanakwirakwizwa muri sisitemu y'amazi.
2.2. Kugenzura indwara
Imwe mumikorere yibanze ya HEC mumazi ya peteroli ni kugenzura rheologiya. Ihindura ubwiza bwamazi kandi itanga ituze mubihe bitandukanye. Uyu mutungo ningirakamaro kugirango ukomeze ibintu bisabwa biranga amazi yo gucukura mugihe cyose cyo gucukura.
2.3. Kugenzura igihombo cyamazi
HEC ni uburyo bwiza bwo kugenzura amazi. Ifasha gukumira gutakaza amazi yo gucukura mu mikorere ikora inzitizi yo gukingira ku rukuta. Uyu mutungo ningirakamaro kugirango ubeho neza kandi ugabanye ibyangiritse.
2.4. Ubushyuhe bukabije
Ibikorwa bya peteroli bikunze guhura nubushyuhe bunini. HEC ihagaze neza kandi ikomeza gukora neza mugucunga rheologiya no gutakaza amazi nubwo haba hari ubushyuhe bwo hejuru bwagaragaye mugucukura neza.
2.5. Guhuza nibindi byongeweho
HEC ihujwe ninyongeramusaruro zinyuranye zikoreshwa mugucukura amazi, nkumunyu, surfactants nizindi polymers. Uku guhuza kwongerera imbaraga kandi kwemerera sisitemu yo gutobora ibicuruzwa byateguwe hashingiwe kumiterere yihariye.
3. Gukoresha mumazi ya peteroli
3.1. Gutobora amazi
Mugihe cyo gucukura, HEC yongewe kumazi yo gucukura kugirango igere kumiterere myiza ya rheologiya. Ifasha kugenzura ubwiza bwamazi, kwemeza gutwara neza ibice byimyitozo hejuru no gukumira ibibazo bidahungabana neza.
3.2. Amazi yuzuye
HEC irashobora gukoreshwa nkumukozi wo kuyungurura mugutwara amazi akoreshwa mugihe cyo kurangiza neza no gukora. Ikora inzitizi kurukuta rwiriba, ifasha kubungabunga neza urukuta no kwirinda kwangirika kwimiterere.
3.3. Amazi yamenetse
Mu kuvunika hydraulic, HEC irashobora gukoreshwa muguhindura imiterere ya rheologiya yamazi yamenetse. Ifasha muburyo bwo guhagarika no gutwara, bigira uruhare mugutsindira inzira yo gucika no gushiraho urusobe rukomeye.
4. Ibitekerezo
4.1. Wibande
Ubwinshi bwa HEC mumazi yo gucukura nikintu gikomeye. Ugomba gutezimbere hashingiwe kumiterere yihariye ya wellbore, ibisabwa byamazi no kuba hari izindi nyongeramusaruro. Gukabya gukoresha cyane cyangwa kudahuza bishobora kugira ingaruka kumikorere.
4.2. Uburyo bwo kuvanga
Uburyo bwo kuvanga neza nibyingenzi kugirango habeho gukwirakwiza HEC mumazi yo gucukura. Kuvanga bituzuye birashobora kuvamo ibintu bitaringaniye, bigira ingaruka kumikorere rusange yamazi.
4.3. Kugenzura ubuziranenge
Ingamba zo kugenzura ubuziranenge ningirakamaro mu gukora no gukoresha HEC mu bikorwa bya peteroli. Ikizamini gikomeye kigomba gukorwa kugirango hamenyekane imikorere ya polymer no kwemeza imikorere ihamye.
5. Ibitekerezo by’ibidukikije n’umutekano
5.1. Ibinyabuzima
Muri rusange HEC ifatwa nk'ibinyabuzima, ni ikintu gikomeye mu gusuzuma ingaruka z’ibidukikije. Ibinyabuzima bigabanya ingaruka zishobora kubaho igihe kirekire cya HEC ku bidukikije.
5.2. Ubuzima n'umutekano
Mugihe HEC ifatwa nkumutekano kugirango ikoreshwe mubikorwa bya peteroli, hagomba gukurikizwa uburyo bukwiye bwo gukumira kugirango birinde. Urupapuro rwumutekano wibikoresho (MSDS) rutanga amakuru yingenzi kubijyanye no gufata neza no gukoresha HEC.
6. Ibizaza hamwe nudushya
Inganda za peteroli na gaze zikomeje gushakisha udushya kugirango tunoze neza gucukura no kugabanya ingaruka z’ibidukikije. Ubushakashatsi burimo gukorwa bwibanze ku guteza imbere polymers nshya ifite imitunganyirize myiza no gushakisha ubundi buryo burambye bwo kongera amazi gakondo.
7. Umwanzuro
Hydroxyethylcellulose igira uruhare runini mu nganda za peteroli na gaze, cyane cyane mu gucukura no kurangiza amazi. Ikomatanya ryihariye ryo kugenzura imvugo, gukumira igihombo cyamazi no guhuza nibindi byongeweho bituma iba ikintu cyingenzi mugukora neza kandi neza. Uko ikoranabuhanga rigenda ritera imbere, ubushakashatsi n’iterambere birashobora gukomeza gutera imbere muri HEC no gucukura amazi, bityo bigafasha mu bushakashatsi burambye kandi bushinzwe gushakisha umutungo wa peteroli na gaze.
