Mumvura yekuchera, PAC inoreva polyanionic cellulose, inova chinhu chakakosha chinoshandiswa mukuchera madhaka.Kuchera madhaka, kunozivikanwawo semvura yekuchera, kunoita basa rakakosha mukuchera matsime eoiri negasi.Inoshanda zvakasiyana-siyana zvezvinangwa, sekutonhodza nekuzora zvibooreso, kutakura zvicherwa kuenda pamusoro, zvichipa kugadzikana kwetsime, uye kudzora kuumbwa kwekumanikidza.
Polyanionic cellulose ipolmer inonyungudika nemvura inotorwa kubva muselulosi, polima yakasikwa inowanikwa muzvirimwa.PAC inowedzerwa kumvura yekuchera kuti iwedzere rheology uye filtration control zvivakwa.
1. Chimiro chemakemikari uye zvivakwa zve polyanionic cellulose (PAC):
PAC ndeye yakagadziridzwa cellulose polymer ine anionic charge.
Chimiro chayo chemakemikari chinoita kuti zvive nyore kunyungudika mumvura, zvichiita sarudzo yakagadzikana.
Iyo anionic chimiro chePAC inobatsira mukukwanisa kwayo kudyidzana nezvimwe zvikamu mumvura yekuchera.
2. Enhanced rheological properties:
PAC inoshandiswa kugadzirisa rheological properties yemvura yekuchera.
Inobata viscosity, gel simba uye kudzora kurasikirwa kwemvura.
Kudzora rheology kwakakosha pakunatsiridza kutakura kwekucheka uye kuchengetedza kugadzikana kwetsime.
3. Sefa yekudzora:
Rimwe remabasa ekutanga ePAC kudzora kurasikirwa kwemvura panguva yekuchera.
Inoumba keke yakaonda, isingapindiki sefa pamadziro etsime, kudzivirira kurasikirwa kwemvura yekuchera mukugadzira.
Izvi zvinobatsira kuchengetedza zvinhu zvinodiwa zvedhaka rekuchera uye kudzivirira kukanganisa kwekugadzira.
4. Wellbore kugadzikana:
PAC inobatsira kugadzikana kwetsime nekudzivirira mvura yakawandisa kuti isapinde mukuumbwa.
Inobatsira kuderedza mutsauko wakanamatira uye mamwe matambudziko ane chekuita nekusagadzikana kwetsime.
Wellbore kugadzikana kwakakosha pakubudirira kwemabasa ekuchera.
5. Mhando dzePAC nemashandisirwo adzo:
Magiredhi akasiyana ePAC anowanikwa zvichienderana nehuremu hwemamorekuru uye dhigirii rekutsiva.
Yakakwira viscosity PACs inowanzo shandiswa uko yakanyanya rheology control inodiwa.
Kune maapplication uko kutadza kurasikirwa kwemvura kuri chinhu chinonyanya kunetseka, yakaderera viscosity PAC inogona kusarudzwa.
6. Mafungiro ezvakatipoteredza:
PAC inowanzoonekwa seine hushamwari kwezvakatipoteredza nekuti inoodza.
Ongororo yekukanganisa kwezvakatipoteredza yakaitwa kuti ive nechokwadi chekushandisa zvine hungwaru uye kuraswa kwemvura yekuchera ine PAC.
7. Kudzora kwemhando uye kuyedzwa:
Matanho akasimba ekudzora hunhu anoitwa kuti ive nechokwadi chekushanda kwePAC mumvura yekuchera.
Miedzo yakasiyana-siyana, kusanganisira kuyerwa kwerheological uye bvunzo yekurasikirwa kwemvura, yakaitwa kuti iongorore mashandiro ePAC-ine madhaka ekuchera.
8. Zvinetso uye zvitsva:
Pasinei nekushandiswa kwakapararira, matambudziko akadai sekugadzikana kwekupisa uye kuenderana nezvimwe zvinowedzera zvinogona kubuda.
Kuenderera mberi nekutsvagisa uye hunyanzvi hwakatsaurirwa kugadzirisa matambudziko aya nekuvandudza mashandiro ePAC mukuchera zvinwiwa.
Polyanionic cellulose (PAC) chinhu chakakosha mukuchera magadzirirwo emvura uye inobatsira mukudzora rheology, kusefa kutonga uye kugadzikana kwetsime.Hunhu hwayo hwakasiyana hunoita kuti ive yekuwedzera kwakakosha muindasitiri yekuchera oiri uye gasi, ichiita basa rakakosha mukubudirira nekubudirira kwekuchera mabasa.
