Uruhare rwa polyacrylamide munganda mu gucukura peteroli

Imiterere ya polyacrylamide yinganda zo kubyimba, flocculation hamwe na rheologiya igenga amazi bituma igira uruhare runini mukubyara peteroli.Ikoreshwa cyane mu gucukura, gucomeka amazi, acide amazi, kuvunika, gukaraba neza, kurangiza neza, kugabanya gukurura, kurwanya ibipimo no kwimura amavuta.

Muri rusange, gukoresha polyacrylamide ni ukuzamura igipimo cyamavuta.By'umwihariko, imirima myinshi ya peteroli yinjiye mu musaruro wa kabiri n'uwa gatatu, ubujyakuzimu bw'ikigega muri rusange burenga metero 1000, kandi bumwe mu burebure bw'ikigega bugera kuri 7000m.Uburinganire bwimiterere nimirima ya peteroli yo hanze byashyizeho uburyo bukomeye kubikorwa byo kugarura peteroli.

Muri byo, umusaruro mwinshi wa peteroli n’umusaruro w’amavuta yo mu mahanga nawo washyize ahagaragara ibisabwa bishya kuri PAM, bisaba ko irwanya ubwoya, ubushyuhe bwo hejuru (hejuru ya 100 ° C kugeza 200 ° C), calcium ion, kurwanya ioni ya magnesium, kurwanya iyangirika ry’amazi yo mu nyanja, kuva mu myaka ya za 1980, intambwe nini imaze guterwa mubushakashatsi bwibanze, gutegura, ubushakashatsi bukoreshwa hamwe niterambere ritandukanye rya PAM ibereye kugarura peteroli mumahanga.

Inganda za polyacrylamide zikoreshwa mugucukura amazi no kongeramo amazi:

Igice cya hydrolyzed polyacrylamide (HPAM), gikomoka kuri hydrolysis ya polyacrylamide, gikoreshwa kenshi muguhindura amazi.Uruhare rwarwo ni uguhindura rheologiya y'amazi yo gucukura, gutwara ibiti, gusiga amavuta bito, kugabanya gutakaza amazi, nibindi. Amazi yo gucukura yahinduwe na polyacrylamide afite uburemere buke bwihariye, bushobora kugabanya umuvuduko no guhagarika ikigega cya peteroli na gaze, byoroshye kubona ikigega cya peteroli na gaze, kandi bifasha mu gucukura, umuvuduko wo gucukura uri hejuru ya 19% ugereranije n’amazi asanzwe yo gucukura, kandi hafi 45% ugereranije n’igipimo cyo gucukura.

Byongeye kandi, irashobora kugabanya cyane impanuka zo gucukura, kugabanya ibikoresho, no gukumira igihombo no kugwa.Kumenagura ikoranabuhanga nigipimo cyingenzi cyo gukangura mugutezimbere uburiri bukomeye mumirima ya peteroli.Polyacrylamide ihuza amazi yamenetse ikoreshwa cyane kubera ubukonje bwayo bwinshi, guterana gake, ubushobozi bwumucanga wahagaritswe, kuyungurura gake, guhagarara neza kwijimye, ibisigara bike, gutanga byinshi, gutegura neza hamwe nigiciro gito.

Mu kuvunika no kuvura aside, polyacrylamide itegurwa mumuti wamazi ufite 0,01% kugeza 4% hanyuma ugashyirwa mubutaka kugirango uvunike.Inganda polyacrylamide yinganda ifite umurimo wo kubyimba no gutwara umucanga no kugabanya igihombo cyamazi yamenetse.Byongeye kandi, polyacrylamide igira ingaruka zo kugabanya guhangana, kugirango igihombo cyoherejwe nigitutu gishobora kugabanuka.
