Hydroxyethyl Cellulose (HEC) ni polymer yamazi ashonga cyane ikoreshwa mugikorwa cyo gucukura amavuta. Imiterere yihariye yumubiri na chimique itanga ibyiza byinshi muriki gice.
1. Kunoza imiterere ya rheologiya
Hydroxyethyl selile ifite imiterere myiza yo kubyimba kandi irashobora kongera cyane ububobere bwamazi yo gucukura. Uyu mutungo ni ingenzi cyane mugihe cyo gucukura, kubera ko amazi yo gucukura cyane afite ubwiza bwinshi ashobora guhagarika gutema imyanda no kubarinda gushira munsi yiziba cyangwa kurukuta rwumuyoboro, bityo bikazamura imikorere yumutekano numutekano. Imyitwarire ya pseudoplastique yibisubizo bya HEC itera ubukonje buke ku gipimo cyo hejuru cyogosha (nko hafi ya drill bit), bigabanya ubukana no kuvoma imbaraga, hamwe nubukonje bwinshi ku gipimo gito (nko hafi y'urukuta rw'iriba), bifasha Kubitwara no guhagarika gukata imyitozo.
2. Ibikoresho byo gufata amazi no kubika amazi
Hydroxyethyl selulose ifite hydrata nziza kandi irashobora gushonga vuba mumazi igakora igisubizo kimwe. Iyi mikorere yorohereza imyiteguro yihuse no guhindura ibimera byamazi kurubuga, byongera imikorere. Byongeye kandi, HEC ifite kandi imbaraga zikomeye zo gufata amazi, zishobora kugabanya guhumeka no gutakaza amazi mumazi yo gucukura no gukomeza gutuza no gukora neza mumazi yo gucukura. Cyane cyane mubushyuhe bwinshi nibidukikije byumuvuduko mwinshi, uburyo bwo kubika amazi burahambaye.
3. Kugenzura
Mugihe cyo gucukura, gutakaza amazi yo gutobora ni ikintu cyingenzi. Gutakaza cyane kuyungurura bizatuma ubwiyongere bwa cake yicyondo, bizatera ibibazo nko kudahungabana kwurukuta no kumeneka neza. Hydroxyethyl selulose irashobora kugabanya neza gutakaza amazi yo gucukura, gukora cake yuzuye ya filteri, kugabanya ibyago byo kumeneka no gusenyuka kurukuta rwiriba, kandi bigateza imbere urukuta rwiriba. Byongeye kandi, HEC irashobora gukomeza imikorere ihamye mubihe bitandukanye bya pH hamwe nubushakashatsi bwa electrolyte kandi bigahuza nubuzima butandukanye bwa geologiya.
4. Ibidukikije byangiza ibidukikije
Mugihe amabwiriza y’ibidukikije agenda arushaho gukomera, icyifuzo cy’ibidukikije byangiza ibidukikije nacyo kiriyongera. Nkibisanzwe bya selile, hydroxyethyl selulose ifite biodegradabilite nziza kandi ntigira ingaruka nke kubidukikije. Ugereranije na polimeri zimwe na zimwe, gukoresha HEC bigabanya ibyuka bihumanya kandi bigafasha kugera ku ntego zo gucukura icyatsi. Byongeye kandi, imiterere idafite uburozi kandi itagira ingaruka ya HEC nayo igabanya ingaruka zishobora kubaho kubuzima bwabakozi.
5. Ubukungu
Nubwo igiciro cya hydroxyethyl selulose kiri hejuru, imikorere yacyo mugihe cyo kuyikoresha irashobora kugabanya cyane igiciro rusange mugihe cyo gucukura. Ubwa mbere, HEC ikora neza kandi igumana amazi igabanya ubwinshi bwamazi yo gucukura nibiciro. Icya kabiri, gutuza no kwizerwa bya HEC bigabanya ibyago byo kunanirwa munsi yubutaka no guhagarara bidateganijwe, kugabanya amafaranga yo kubungabunga no gusana. Hanyuma, umutungo wa HEC utangiza ibidukikije ugabanya amafaranga yakoreshejwe mu guta imyanda no kubahiriza ibidukikije.
6. Guhuza no Guhindagurika
Hydroxyethyl selulose ifite imiti ihamye kandi ihuza byinshi, kandi irashobora guhuzwa ninyongeramusaruro zitandukanye hamwe na sisitemu yo gutobora amazi kugirango ikore sisitemu igizwe nibikorwa byihariye. Kurugero, HEC irashobora gukoreshwa hamwe nuburyo bwo kurwanya gusenyuka, imiti igabanya ubukana hamwe n’amavuta kugira ngo tunoze imikorere yuzuye y’amazi yo gucukura kandi yujuje imiterere ya geologiya hamwe n’ibikenewe. Byongeye kandi, HEC irashobora kandi gukoreshwa mubindi bikoresho bya peteroli nko mumazi yo kurangiza no kuvunika amazi, bikerekana byinshi.
Hydroxyethyl selulose ifite ibyiza byingenzi mu gucukura peteroli, bigaragarira cyane cyane mu kunoza imiterere ya rheologiya, kongera amazi no gufata neza amazi, kugenzura neza ingano yo kuyungurura, kuba bitangiza ibidukikije, ubukungu ndetse n’imikorere myinshi. Izi nyungu zituma HEC iba ingenzi kandi yingirakamaro mubikorwa byo gucukura peteroli, bifasha kugera kubikorwa byo gucukura neza, umutekano kandi bitangiza ibidukikije. Hamwe nogukomeza gutera imbere kwikoranabuhanga no kurushaho gushira mubikorwa, ibyifuzo byo gukoresha hydroxyethyl selulose mugucukura peteroli bizaba binini.
