Selulose ya hydroxyethyl yo mu rwego rwa peteroli (HEC), nk'ikintu cy'ingenzi gishongesha polymer mu mazi, uburyo bwo guhindura rheology, n'uburyo bwo gushimangira, byarushijeho kugira agaciro mu bijyanye no gucukura peteroli na gaze mu myaka ya vuba aha. Bitewe no kwaguka guhoraho kw'amariba maremare, amariba maremare cyane, no gushakisha peteroli na gaze mu buryo budasanzwe, hakenewe cyane imikorere y'amariba yo gucukura, amariba yo gucika, n'amariba yo kurangiza. HEC, ifite ubushobozi bwo gushonga neza, ubushobozi bwo gushonga neza, n'ubushobozi bwo gukuba, yabaye inyongeramusaruro ikomeye mu kunoza imikorere y'amariba na gaze.
HEC yo mu rwego rwa peteroli igaragaza ubushobozi bwiza bwo gushonga no gukurura amazi, bigatuma habaho uburyo bumwe bwo gucukura amazi, yongera ubukana bw'amazi, bityo bigatuma ubushobozi bwo gutwara amazi burushaho kuba bwiza. Mu gihe cyo gucukura, ibice biri hasi y'icyobo bigomba gukurwaho neza mu gihe cy'ubushyuhe bwinshi, umuvuduko mwinshi, no mu gihe cyo gutembera vuba. Amazi yo gucukura afite ubukana bwa HEC yongera ubushobozi bwo guhagarika no gutwara, itwara vuba ibice ku mutwe w'icyobo kandi ikirinda ibyago byo gupfunyika imiyoboro bitewe n'ibice byirundanyije hasi y'icyobo. Byongeye kandi, HEC ihura neza n'amazi y'amazi n'amazi yo mu nyanja, ikomeza gukora neza ndetse no mu bidukikije bifite umunyu mwinshi, bigatuma ikoreshwa neza cyane mu kurema ahantu hatandukanye mu nyanja no mu bikorwa bigoye byo kubaka.
HEC kandi igira uruhare runini mu kurangiza no gushimangira sisitemu z'amazi. Inoza imyitwarire y'amazi mu mitsi, igakomeza gutakaza amazi make kandi ikongera ubwiza bwa keke y'urufunguzo. Keke y'urufunguzo nziza, yoroheje kandi ikomeye itandukanya neza amazi yo mu ikorwa, ikagabanya kwangirika kw'ikigega kandi ikarinda ko umusaruro ukomeza. Byongeye kandi, HEC yongera cyane ubushobozi bwo gusunika amazi no gufunga amazi yo mu ikorwa, bigatuma imikorere yayo igenda neza kandi mu mutekano.
Mu ikoranabuhanga ryo gushwanyagurika, HEC yo mu rwego rwa peteroli ni igice cy'ingenzi cy'amazi yo gushwanyagurika akora neza. Ubushobozi bwayo bwo gukuba butuma amazi yo gushwanyagurika ashobora gutwara igice kinini cy'amazi mu mvune zimbitse, bigatuma ikigega gihinduka neza. Mu gihe cyo gushwanyagurika, ubushyuhe n'imbaraga zo gukata biba biri hejuru cyane, nyamara HEC igumana imiterere myiza ya viscoelastic, igabanya umucanga uhagarara kandi ikongera imbaraga zo gushwanyagurika. Ku rundi ruhande, HEC ifite imiterere yo kwangirika ishobora kugenzurwa; nyuma yo kubakwa, ishobora kwangirika mu bihe bikwiye, ikareka imvune, ikagabanya ubudahangarwa bw'amazi, ikarinda urujya n'uruza rw'amazi, bityo ikongera umusaruro. Mu bijyanye no kurinda ibidukikije n'umutekano, HEC ntabwo ari uburozi, irabora, kandi ntitera umujinya, bigatuma iba inyongeramusaruro y'ibinyabutabire bihumanya ibidukikije kandi birengera ibidukikije. Mu gihe isi yose yibanda ku ngufu zihumanya ibidukikije n'iterambere rirambye, HEC ntiyujuje gusa ibisabwa ku bidukikije ku binyabutabire byo mu bikomoka kuri peteroli ahubwo inafasha amasosiyete kunoza urwego rwayo rwo gucunga ibidukikije. Ugereranyije na polymer zisanzwe zikoze mu byuma, HEC ifite uburyo bwiza bwo kubungabunga ibidukikije no kubika no gutwara, bigatuma habaho gahunda yo kugabanya karuboni kandi itekanye mu iterambere rya peteroli na gaze.
Ikoreshwa ry'urwego rwa peteroliHECYanagutse mu nzego nyinshi, harimo kongera ubwiyongere bw'amavuta, kurinda ikigega cy'amazi, no kunoza imikorere y'uburyo bwo gucukura amazi. Ikorana neza n'uburyo butandukanye bwo gucukura amazi rituma rikorana n'ibintu bitandukanye bikoresha surfactants, umunyu, n'ibindi bihuza kugira ngo bikore uburyo bwinshi bwo gucukura amavuta. Urugero, mu gucukura amavuta menshi, HEC ishobora kunoza imikorere y'uburyo bwo gucukura no kongera imikorere myiza y'uburyo bwo gucukura; mu mikorere y'amariba ya gaze, uburyo bwo gukurura HEC bushobora gutwara no gusohora amazi neza, bigatuma umusaruro w'amariba ya gaze urushaho kwiyongera.
Kubera ko ifite ubushobozi bwo gukuba neza, guhagarika, imiterere yayo myiza yo guhuza imikorere y’amaraso, hamwe n’imiterere myiza y’ibidukikije, HEC yo mu rwego rwa peteroli yabaye igikoresho cy’ingenzi mu gucukura peteroli na gaze mu buryo bugezweho. Haba mu gucukura, gusimbuza sima, gushwanyagurika, cyangwa kurangiza ibikorwa, HEC ishobora kunoza cyane imikorere myiza n’umutekano w’imikorere, igatanga umusanzu mu iterambere ryiza no gukoresha neza umutungo wa peteroli na gaze mu buryo burambye.
