Uruhare rwinganda rwa polyacrylamide mumavuta

Imitungo ya polyacrylampide yo kubyimba, gusenya n'amabwiriza y'amazi y'amazi agira uruhare runini mu musaruro wa peteroli. It is widely used in drilling, water plugging, acidizing water, fracturing, well washing, well completion, drag reduction, anti-scale and oil displacement.

Muri rusange, gukoresha polyacrylamide ni kunoza umubare wamavuta. By'umwihariko, imirima myinshi ya peteroli yinjiye mu gisaruro cya kabiri kandi ya tertiary, ubujyakuzimu bw'ikigega muri rusange burenze 1000M, kandi bumwe mu bujyakuzimu bw'uwakigega bugera kuri 7000m. Kwihitiramo imirima n'amavuta yo hanze byashyize ahagaragara ibintu byinshi bifatika kubikorwa byo kugarura amavuta.

Muri bo, umusaruro w'imbitse wa peteroli no gufatanya na peteroli bivuga kandi ushyira ahagaragara ibisabwa bishya kuri Pam, bisaba ko urwanya ubushakashatsi bw'ibanze, kwitegura kwa Dadiyo, mu myaka ya 2000, iterambere ry'inyanja kandi rishingiye ku gitsina gakomeye rya pam rikwiriye kugarura amavuta mu mahanga.

Inganda Polyacrylalide ikoreshwa nko gucukura amazi no kuvunika amazi:

Igice cya hydrolyzted polyacrylamide (HPAM), ikomoka kuri hydrolysis ya polyacrylalipide, ikunze gukoreshwa nkamazi yo gucukura. Uruhare rwayo ni ugukoresha imvugo yo gucukura amazi, gutwara ibiti, gusiga umuvuduko wamavuta, nibindi bishobora kugabanya umuvuduko wa peteroli na polsecrylamide. Amazi, hamwe na 45% hejuru yumuvuduko wo gucukura.

Byongeye kandi, birashobora kugabanya cyane impanuka zo gushimisha, kugabanya ibikoresho byambara, kandi birinde igihombo no kugwa. Ikoranabuhanga rirerekana ni ingamba zikomeye zo guteza imbere ibitanda bikabije mu nzego za peteroli. Polyacrylamide ya Crolsallimes Amazi akoreshwa cyane kubera ubushyuhe bwinshi, amakimbirane yo mu mucanga, ubudodo buke, ibisigisigi byiza, ibisigisigi byiza, ibisigisigi byoroshye.

Mu kuvunika no gucika bugufi, Polyacrylalide yateguwe mu muco utangaje hamwe na 0.01% kugeza kuri 4% kandi bikandagira mu nsi yo gutondekanya mu nsinda. Igisubizo cyinganda cya polyacrylalide gifite imikorere yo kubyimba no gutwara umucanga no kugabanya gutakaza amazi avunika. Byongeye kandi, polyacrylamide ifite ingaruka zo kugabanya kurwanya, kugirango igihombo cyo kwihererekanya igitutu kirashobora kugabanuka.
