Ukusetyenziswa kwePAC kukomba ioyile
Isishwankathelo
I-Poly anionic cellulose, efinyeziweyo njenge-PAC, yi-derivative cellulose ether derivative enyibilikayo eveliswa yi-chemical modification ye-cellulose yendalo, ibalulekile i-cellulose e-ether enyibilikayo emanzini, ngumgubo omhlophe okanye otyheli kancinane, ongeyotyhefu, ongenancasa. Inokunyibilika emanzini, inozinzo oluhle lobushushu kunye nokumelana netyuwa, kunye neempawu ezinamandla zokulwa ne-antibacterial. I-fluid yodaka eyenziwe kunye nale mveliso inokunciphisa ukulahleka kwamanzi okulungileyo, ukuvinjelwa kunye nokumelana nokushisa okuphezulu. Isetyenziswa kakhulu ekugrunjweni kwe-oyile, ngakumbi amaqula amanzi anetyuwa kunye nokugrumba i-oyile ngaphandle konxweme.
Iimpawu zePAC
Yeyokucoceka okuphezulu kwe-ionic cellulose, iqondo eliphezulu lokutshintshwa kunye nokuhanjiswa okufanayo kwezinto ezithatha indawo. Ingasetyenziswa njenge-ejenti yokuqina, i-rheology modifier, i-arhente yokunciphisa ilahleko yamanzi kunye nokunye.
1.Ifanele ukusetyenziswa kulo naluphi na udaka ukusuka kumanzi amatsha ukuya kumanzi anetyuwa ahluthisiweyo.
I-2.I-PAC ye-viscosity ephantsi inokunciphisa ngokufanelekileyo ilahleko yokuhluza kwaye inganyusi kakhulu i-mucus yenkqubo.
3.I-viscosity ephezulu yePAC inesivuno esikhulu sodaka kunye nesiphumo esicacileyo sokuthoba ilahleko yamanzi. Ngokukodwa ifanelekile kwi-slurry ye-low-solid-phase-slurry kunye ne-non-solid-phase yetyuwa yamanzi e-slurry.
4.Imijelo yodaka eyenziwe ngePAC inqanda udongwe kunye nokusasazeka kweshale kunye nokwandiswa kwendawo enetyuwa eninzi, ngaloo ndlela ivumela ukungcoliseka kodonga lomthombo ukuba kulawulwe.
5.Ukugrumba udaka okugqwesileyo kunye nolwelo olusebenzayo, ulwelo olusebenzayo lokuqhekeza.
PACIsicelo
1.PAC isicelo kulwelo kusombiwa.
I-PAC ilungele ukusetyenziswa njenge-inhibitor kunye ne-arhente yokunciphisa ilahleko yamanzi. Imijelo yodaka eyenziwe yePAC inqanda ukusasazwa kodongwe kunye ne-shale kunye nokudumba kwindawo ephezulu yetyuwa, ngaloo ndlela ivumela ukungcoliseka kodonga olulungileyo ukuba kulawulwe.
2. Isicelo sePAC kulwelo lomsebenzi.
Well workover fluids eziqulunqwe kunye PAC ziqinileyo-eziqinileyo, ezingathinteli ukugqwesa kokwenziwa kwemveliso kunye nezinto eziqinileyo kwaye zingonakalisi ukubunjwa kwemveliso; kwaye ube nelahleko yamanzi aphantsi, okunciphisa amanzi angena kwisakhiwo sokuvelisa.
Ikhusela ukubunjwa kokuvelisa kumonakalo osisigxina.
Yiba namandla okucoca amaqula , ukugcinwa kwamaqula kuncitshisiwe.
Inamandla okumelana nokungena kwamanzi kunye nentlenga kwaye ayifane ibe namagwebu.
Inokugcinwa okanye idluliselwe phakathi kwamaqula namaqula, ixabiso eliphantsi kunolwelo oluqhelekileyo lokusebenza ngodaka.
3. Ukusetyenziswa kwePAC kwifracturing fluid.
Ulwelo oluqhekekayo oluyilwe nePAC lusebenza kakuhle ukunyibilika. Kulula ukuyisebenzisa, kwaye inesantya esikhawulezayo sokwakheka kwejeli kunye nomthamo owomeleleyo wokuthwala isanti. Inokusetyenziselwa ukubunjwa koxinzelelo lwe-osmotic ephantsi, kwaye umphumo wayo wokuqhekeka ugqwesileyo.
