Hydroxyethyl selulose (HEC) ni polymer yingenzi iboneka mumazi igira uruhare runini mugucukura peteroli. Nkibikomoka kuri selile bifite imiterere yihariye yumubiri nubumashini, HEC ikoreshwa cyane mubikorwa byo gucukura peteroli no mumushinga utanga amavuta.
1. Ibintu shingiro bya hydroxyethyl selulose (HEC)
Hydroxyethyl selulose (HEC) ni ionic water-soluble polymer compound iboneka muguhindura imiti ya selile naturel. Mu kwinjiza amatsinda ya hydroxyethyl mumiterere ya selile ya selile, HEC ifite hydrophilicity ikomeye, kuburyo ishobora gushonga mumazi kugirango ibe igisubizo cya colloidal hamwe nubwiza runaka. HEC ifite imiterere ihamye ya molekuline, irwanya ubushyuhe bukomeye, ugereranije nubushakashatsi bwimiti, kandi ntabwo ari uburozi, impumuro nziza, kandi ifite ibinyabuzima byiza. Ibi biranga bituma HEC yongerera imiti neza mu gucukura peteroli.
2. Uburyo bwa HEC mu gucukura peteroli
2.1 Kugenga ibishishwa byamazi
Mugihe cyo gucukura amavuta, gucukura amazi (bizwi kandi no gucukura ibyondo) ni amazi yingirakamaro cyane, akoreshwa cyane mugukonjesha no gusiga amavuta ya biti, gutwara ibiti, gutuza urukuta rwiriba, no kwirinda guturika. HEC, nkumuhinduzi wibyimbye na rheologiya, irashobora kunoza imikorere yayo muguhindura ubwiza bwimiterere nibisobanuro byamazi yo gucukura. HEC imaze gushonga mumazi yo gucukura, ikora imiterere yibice bitatu byurusobe, bigatezimbere cyane ubwiza bwamazi yo gucukura, bityo bikazamura ubushobozi bwo gutwara umucanga bwamazi yo gucukura, bigatuma ibice bishobora gusohoka neza bivuye kuri munsi y'iriba, no gukumira kuziba neza.
2.2 Nibyiza kurukuta no gukumira gusenyuka neza
Nibyiza kurukuta nikibazo gikomeye mubucukuzi. Bitewe nuburyo bugoye bwimiterere yubutaka hamwe nikinyuranyo cyumuvuduko ukomoka mugihe cyo gucukura, urukuta rwiriba akenshi rushobora gusenyuka cyangwa guhungabana. Imikoreshereze ya HEC mu gucukura amazi irashobora kunoza neza ubushobozi bwo kugenzura iyungurura ryamazi yo gucukura, kugabanya igihombo cyo kuyungurura amazi yo gucukura kugirango ikorwe, hanyuma ikore cake yuzuye ibyondo, ucomeke neza uduce duto duto twa rukuta rwiriba, kandi wirinde neza urukuta rudahinduka. Ingaruka ningirakamaro cyane mugukomeza ubusugire bwurukuta rwiriba no kwirinda gusenyuka neza, cyane cyane mubice bifite ubwikorezi bukomeye.
2.3 Sisitemu yo hasi yicyiciro cyiza nibidukikije
Umubare munini wibice bikomeye byongerwaho muburyo bwa gakondo bwo gucukura kugirango urusheho gukomera no gutuza kwamazi. Nyamara, ibice nkibi bikunda kwambara kubikoresho byo gucukura kandi bishobora gutera umwanda wibigega mumasoko ya peteroli akurikira. Nukubyimbye neza, HEC irashobora kugumana ubwiza bwimiterere nubwiza bwa rheologiya byamazi yo gucukura mugihe ibintu bitarimo ibintu bike, kugabanya kwambara kubikoresho, no kugabanya ibyangiritse kubigega. Byongeye kandi, HEC ifite ibinyabuzima byiza kandi ntibizatera umwanda urambye ibidukikije. Kubwibyo, hamwe nibisabwa cyane kurengera ibidukikije muri iki gihe, ibyiza byo gukoresha HEC biragaragara cyane.
3. Ibyiza bya HEC mu gucukura peteroli
3.1 Amazi meza yo gukomera hamwe ningaruka zo kubyimba
HEC, nkibikoresho byamazi ya polymer iboneka, ifite ibisubizo byiza mubihe bitandukanye byamazi meza (nkamazi meza, amazi yumunyu, nibindi). Ibi bifasha HEC gukoreshwa muburyo butandukanye bwibidukikije bya geologiya, cyane cyane mubidukikije bwumunyu mwinshi, kandi birashobora gukomeza gukora neza. Ingaruka yacyo yibyingenzi irahambaye, irashobora kunoza neza imiterere ya rheologiya yamazi yo gucukura, kugabanya ikibazo cyo gutema ibiti, no kunoza imikorere.
3.2 Ubushyuhe buhebuje no kurwanya umunyu
Mubucukuzi bwimbitse na ultra-deep, gucukura ubushyuhe nigitutu kiri hejuru, kandi amazi yo gucukura yibasirwa byoroshye nubushyuhe bwo hejuru hamwe numuvuduko mwinshi kandi bigatakaza imikorere yambere. HEC ifite imiterere ihamye ya molekuline kandi irashobora kugumana ubwiza bwayo hamwe na rheologiya mubushyuhe bwinshi hamwe nigitutu. Byongeye kandi, ahantu hashyizwemo imyunyu myinshi, HEC irashobora gukomeza kugira ingaruka nziza yo kubyimba kugirango irinde amazi yo gucukura kutanyeganyega cyangwa guhungabana bitewe no kwivanga kwa ion. Niyo mpamvu, HEC ifite ubushyuhe buhebuje hamwe n’umunyu mwinshi mubihe bigoye bya geologiya kandi ikoreshwa cyane mumariba maremare hamwe nimishinga itoroshye yo gucukura.
3.3 Gukora neza
Ibibazo byo guterana mugihe cyo gucukura nabyo ni ikintu cyingenzi kigira ingaruka kumikorere. Nka kimwe mu bisiga amavuta yo gucukura, HEC irashobora kugabanya cyane coeffisiyoneri yo guterana hagati yibikoresho byo gucukura ninkuta nziza, kugabanya kwambara ibikoresho, no kongera igihe cyibikorwa byo gucukura. Iyi mikorere iragaragara cyane mumariba atambitse, amariba yegeranye nubundi bwoko bwiriba, bifasha kugabanya ibibaho kunanirwa kumanuka no kunoza imikorere muri rusange.
4. Gushyira mu bikorwa no kwirinda HEC
4.1 Uburyo bwo gufata no kugenzura ibitekerezo
Uburyo bwo gufata imiti ya HEC bugira ingaruka ku buryo butaziguye no gusesa mu gucukura amazi. Mubisanzwe, HEC igomba kongerwaho buhoro buhoro mumazi yo gucukura mugihe gikurura kugirango irebe ko ishobora gushonga kandi ikirinda guhuriza hamwe. Muri icyo gihe, imikoreshereze y’imikoreshereze ya HEC igomba kugenzurwa mu buryo bushyize mu gaciro ukurikije imiterere yabyo, ibisabwa byo gukora amazi, nibindi byinshi. mugihe gito cyane kwibandaho ntigushobora gukoresha neza ingaruka zayo zo kubyimba no gusiga. Kubwibyo, mugihe ukoresheje HEC, igomba kuba nziza kandi igahinduka ukurikije ibihe bifatika.
4.2 Guhuza nibindi byongeweho
Muri sisitemu yo gucukura amazi nyayo, inyongeramusaruro zinyuranye zongerwaho kugirango zigere kumirimo itandukanye. Kubwibyo, guhuza hagati ya HEC nibindi byongeweho nabyo ni ibintu bigomba kwitabwaho. HEC yerekana guhuza neza ninyongeramusaruro nyinshi zisanzwe zogucukura nka kugabanya igihombo cyamazi, amavuta yo kwisiga, stabilisateur, nibindi, ariko mubihe bimwe na bimwe, inyongeramusaruro zimwe zishobora kugira ingaruka kumubyimba cyangwa gukomera kwa HEC. Kubwibyo, mugihe utegura formulaire, birakenewe ko dusuzuma byimazeyo imikoranire yinyongeramusaruro zinyuranye kugirango habeho ituze no guhora mubikorwa byo gucukura.
4.3 Kurengera ibidukikije no gutunganya imyanda
Hamwe n’amabwiriza arushijeho gukomera yo kurengera ibidukikije, ubucuti bw’ibidukikije bwamazi yo gucukura bwagiye bwitabwaho buhoro buhoro. Nibikoresho bifite ibinyabuzima byiza, gukoresha HEC birashobora kugabanya neza umwanda w’amazi yo gucukura ibidukikije. Ariko, nyuma yo gucukura birangiye, amazi yimyanda irimo HEC aracyakeneye kuvurwa neza kugirango birinde ingaruka mbi kubidukikije. Muri gahunda yo gutunganya imyanda y’amazi, uburyo bwo gutunganya siyanse nko gufata imyanda no kwangirika bigomba gukoreshwa hifashishijwe amabwiriza yo kurengera ibidukikije ndetse n’ibisabwa tekinike kugira ngo ingaruka ku bidukikije zigabanuke.
Hydroxyethyl selulose (HEC) igira uruhare runini mu gucukura amavuta. Hamwe namazi meza cyane yo gukomera, kubyimba, ubushyuhe hamwe no kurwanya umunyu ningaruka zo gusiga, bitanga igisubizo cyizewe cyo kunoza imikorere yamazi yo gucukura. Mubihe bigoye bya geologiya hamwe nibidukikije bikora, ikoreshwa rya HEC rirashobora kunoza neza gucukura, kugabanya ibikoresho, no kwemeza neza neza. Hamwe niterambere ryiterambere rya tekinoroji yinganda za peteroli, ibyifuzo bya HEC mugucukura peteroli bizaba binini.
