Udindo wa mafakitale Polyacrylamide mu mafuta m'zigawo

The zimatha mafakitale Polyacrylamide kwa thickening, flocculation ndi rheological malamulo amadzimadzi kupanga ndi mbali yofunika kwambiri kupanga mafuta.Amagwiritsidwa ntchito kwambiri pobowola, plugging madzi, acidizing madzi, fracturing, kutsuka bwino, kumaliza bwino, kukoka kuchepetsa, odana ndi sikelo ndi kusamuka mafuta.

Ambiri, ntchito Polyacrylamide ndi kusintha mlingo kuchira mafuta.Makamaka, minda yambiri yamafuta yalowa m'magawo achiwiri ndi apamwamba, kuya kwa nkhokwe nthawi zambiri kumakhala kopitilira 1000m, ndipo kuya kwamadziwo kumafikira 7000m.Kusiyanasiyana kwa mapangidwe ndi minda yamafuta akunyanja kwapangitsa kuti pakhale zovuta kwambiri pakubwezeretsa mafuta.

Pakati pawo, kupanga mafuta akuya komanso kupanga mafuta am'mphepete mwa nyanja kumaperekanso zofunikira zatsopano za PAM, zomwe zimafuna kukana kukameta ubweya, kutentha kwambiri (kuposa 100 ° C mpaka 200 ° C), calcium ion, kukana kwa magnesium ion, kukana kuwonongeka kwa madzi a m'nyanja, kuyambira m'ma 1980, kupita patsogolo kwakukulu kwapangidwa mu kafukufuku woyambira, kukonzekera, kafukufuku wogwiritsa ntchito komanso chitukuko cha PAM choyenera kuchira mafuta kunja.

Industrial Polyacrylamide ntchito ngati kubowola madzimadzi chosinthira ndi fracturing madzimadzi zowonjezera:

Pang'ono hydrolyzed Polyacrylamide (HPAM), amene anachokera ku hydrolysis wa Polyacrylamide, nthawi zambiri ntchito monga pobowola zosintha madzimadzi.Udindo wake ndi kuwongolera rheology ya pobowola madzimadzi, kunyamula cuttings, mafuta pobowola pang'ono, kuchepetsa kutaya madzimadzi, etc. The pobowola madzimadzi modulated ndi polyacrylamide ali otsika enieni mphamvu yokoka, amene akhoza kuchepetsa mavuto ndi blockage pa mafuta ndi mpweya posungira, zosavuta kupeza posungira mafuta ndi gasi, ndi yabwino kubowola, liwiro pobowola ndi 19% apamwamba kuposa ochiritsira pobowola madzimadzi, ndipo pafupifupi 45% apamwamba kuposa mawotchi mlingo pobowola.

Kuphatikiza apo, imatha kuchepetsa kwambiri ngozi zobowola, kuchepetsa kuwonongeka kwa zida, komanso kupewa kuwonongeka ndi kugwa.Tekinoloje ya Fracturing ndi njira yolimbikitsira yopangira mabedi olimba m'minda yamafuta.Polyacrylamide crosslinked fracturing fluid imagwiritsidwa ntchito kwambiri chifukwa cha kukhuthala kwake kwakukulu, kukangana kochepa, mphamvu ya mchenga woyimitsidwa, kusefera pang'ono, kukhazikika kwamakayendedwe abwino, zotsalira zazing'ono, zotsalira zambiri, kukonzekera bwino ndi mtengo wotsika.

Mu fracturing ndi acidizing mankhwala, Polyacrylamide zakonzedwa mu amadzimadzi njira ndi ndende ya 0,01% kuti 4% ndi amapopa mu mobisa mapangidwe fracture mapangidwe.The mafakitale polyacrylamide njira ali ndi ntchito ya thickening ndi kunyamula mchenga ndi kuchepetsa imfa ya fracturing madzimadzi.Kuphatikiza apo, polyacrylamide imakhala ndi mphamvu yochepetsera kukana, kotero kuti kuwonongeka kwa kutengerako kungathe kuchepetsedwa.
