Polyanionic Cellulose oildrilling

Polyanionic selulose (PAC) ninyongera yingenzi mumazi yo gucukura amavuta, akora imirimo itandukanye kugirango ibikorwa byogucukura neza. Dore uko PAC igira uruhare mu gucukura amavuta:

1. Igenzura rya Viscosity: PAC ifasha kugenzura ubwiza bwamazi yo gucukura, ikemeza ko ifite umubyimba ukenewe kugirango itware neza ibice byacukuwe hejuru. Ibi nibyingenzi mukubungabunga umutekano mwiza no gukumira ibibazo nko gusenyuka.
2. Kwirinda gutakaza ibicurane: PAC ikora cake yoroheje, idashobora kwungururwa kurukuta rwa borehole, bigabanya gutakaza amazi mumiterere ikikije. Mugabanye igihombo cyamazi, PAC ifasha kugumana umuvuduko wa hydrostatike, irinda kwangirika kwimiterere, kandi itezimbere umusaruro mwiza.
3. Guhindura Rheologiya: PAC igira ingaruka kumyitwarire yimiterere nimiterere ya rheologiya yamazi yo gucukura, byongera ihagarikwa ryibintu kandi bikagabanya gutuza. Ibi bituma imikorere idahwitse yimyanda itandukana mubihe bitandukanye.
4. Kugabanya Amavuta no Kugabanya: PAC itanga amavuta hagati yumugozi wimyitozo nurukuta rwa wellbore, kugabanya guterana no kugabanya gukurura. Ibi bifasha kunoza imikorere yo gucukura, kugabanya kwambara kubikoresho byo gucukura, no kongera ubuzima ubuzima.
5. Kongera isuku mu mwobo: Mu kongera ubukonje no gutwara ubushobozi bwamazi yo gucukura, PAC yorohereza kuvanaho imyanda yacukuwe hamwe n’imyanda iva ku iriba, kunoza imikorere yo gusukura umwobo no kugabanya ingaruka ziterwa n’umuyoboro wafashwe.
6. Ubushyuhe nubunyu bwumunyu: PAC yerekana kwihanganira ubushyuhe bwinshi nubunyu, ikomeza ubwiza bwayo nibikorwa biranga ubushyuhe butandukanye hamwe nubunyu bwagaragaye mubikorwa byo gucukura.
7. Ibidukikije byangiza ibidukikije: PAC ikomoka ku masoko ashobora kuvugururwa ashingiye ku bimera kandi irashobora kwangirika, bigatuma itangiza ibidukikije kandi ikwiriye gukoreshwa ahantu hacukurwa ibidukikije.

Muri make, selile ya polyanionic nikintu cyingenzi cyamazi yo gucukura amavuta, atanga viscosifike, kugenzura igihombo cyamazi, guhindura rheologiya, nibindi bintu bikomeye kugirango ibikorwa byogucukura neza kandi neza mubikorwa bya peteroli na gaze. Kwizerwa kwayo, imikorere, hamwe no guhuza ibidukikije bituma ihitamo neza mugutezimbere imikorere ya dring fluid hamwe na stabilite nziza.
