PAC (Polyanionic Cellulose)

I-Polyanionic cellulose (PAC) i-polymer e-soluble yamanzi ephuma kwi-cellulose, i-compound eyenzeka ngokwemvelo efumaneka kwizityalo. IPAC isetyenziswa kakhulu kumashishini ahlukeneyo, kuquka ukombiwa kwe-oyile, ngenxa yeempawu zayo ezizodwa kunye nokuguquguquka kwayo. Kumxholo wokomba ioyile, iPAC isebenza imisebenzi emininzi ebalulekileyo kulwelo lokomba:

1. I-Viscosification: I-PAC isetyenziswa ngokuyintloko njenge-viscosifier kumanzi okugaya amanzi. Inceda ukwandisa i-viscosity yolwelo, iphucula amandla ayo okumisa kunye nokuthutha i-cuttings egrunjiweyo kunye nezinye izinto eziqinileyo phezulu. Oku kunceda ekugcineni uzinzo lwequla kunye nokuthintela ukudilika komngxuma.
2. Ulawulo lwelahleko yolwelo: I-PAC yenza ikeyiki ecekethekileyo, engangenekiyo yokuhluza kwiindonga zomthombo, inciphisa ilahleko yolwelo lokugrumba ekubunjweni okujikelezileyo. Oku kunceda ukugcina ingqibelelo ye-wellbore, kuthintela umonakalo wokwakheka, kunye nokuphucula ukusebenza kakuhle kokomba.
3. Ukuguqulwa kwe-Rheology: I-PAC inefuthe kwindlela yokuziphatha kunye neempawu ze-rheological zokucoca ulwelo, ukwandisa ukunqunyanyiswa kwezinto eziqinileyo kunye nokunciphisa ukuzinza. Oku kuqinisekisa ukusebenza okungaguquguqukiyo kolwelo lokomba phantsi kweemeko ezahlukeneyo zomngxuma.
4. Ukucocwa komngxuma: Ngokunyusa i-viscosity kunye nokuthwala umthamo we-drilling fluid, i-PAC iphucula ukusebenza kakuhle kokucoca umngxuma, iququzelele ukukhutshwa kwe-cuttings drilled kunye ne-debris kwi-wellbore.
5. Iqondo lobushushu kunye nokuzinza kobutyuwa: I-PAC ibonisa ukunyamezela okuphezulu kwe-thermal kunye netyuwa, igcina i-viscosity yayo kunye neempawu zokusebenza kuluhlu olubanzi lwamaqondo obushushu kunye neetyuwa ezifunyenwe kwimisebenzi yokugaya.
6. Isebenzisana kakuhle nokusiNgqongileyo: I-PAC ithathwe kwimithombo ehlaziyekayo esekwe kwizityalo kwaye iyakwazi ukubola, oko kuyenza ikhuseleke nokusingqongileyo kwaye ifaneleke ukuba isetyenziswe kwiindawo zokomba ezinobuthathaka kokusingqongileyo.

I-PAC ifumaneka kumabakala ahlukeneyo kunye neenkcukacha ezilungiselelwe iimfuno ezithile zolwelo lokomba kunye neemeko zokusebenza. Amanyathelo olawulo lomgangatho aqinisekisa ukuhambelana kunye nokuthotyelwa kwemigangatho yoshishino, kubandakanywa ne-API (i-American Petroleum Institute) inkcazo ye-drilling fluid additives.

Isishwankathelo, i-polyanionic cellulose (i-PAC) yongezwa okubalulekileyo kumanzi okugaya i-oyile kunye negesi, ukubonelela nge-viscosification, ukulawulwa kwelahleko yamanzi, ukuguqulwa kwe-rheology, kunye nezinye iimpawu eziphambili ezinegalelo ekusebenzeni ngokufanelekileyo kunye nempumelelo yokugaya.
