Polyanionic Cellulose oildrilling

I-Polyanionic cellulose (PAC) sisongezelelo esibalulekileyo kulwelo lokomba ioyile, lusebenza imisebenzi eyahlukeneyo ukwenza imisebenzi yokomba. Nantsi indlela iPAC enegalelo ngayo kulwelo lwe-oyile yokomba:

1. Ulawulo lwe-Viscosity: I-PAC inceda ukulawula i-viscosity ye-drilling fluid, iqinisekisa ukuba inobunzima obufunekayo ukuze ithwale ngokufanelekileyo izicucu eziqhekekileyo kumphezulu. Oku kubalulekile ekugcineni uzinzo kunye nokuthintela imiba efana nokudilika komngxuma.
2. UThintelo lokuLahleka kolwelo: I-PAC yenza ikeyiki ecekethekileyo, engangenekiyo yokuhluza kudonga lomngxuma, inciphisa ukulahleka kolwelo kukwakheka okujikelezileyo. Ngokunciphisa ilahleko yolwelo, iPAC inceda ukugcina uxinzelelo lwe-hydrostatic, inqanda ukonakala kokwakheka, kwaye iphucule imveliso kakuhle.
3. Ukuguqulwa kweRheology: I-PAC inefuthe kwindlela yokuziphatha kunye neempawu ze-rheological zolwelo lokomba, ukunyusa ukumiswa kwezinto eziqinileyo kunye nokunciphisa ukuhlaliswa. Oku kuqinisekisa ukusebenza okungaguquguqukiyo kolwelo lokomba phantsi kweemeko ezahlukeneyo zomngxuma.
4. I-Lubrication kunye nokuNcitshiswa kweFriction: I-PAC ibonelela ngokuthambisa phakathi komtya we-drill kunye nodonga lomthombo, ukunciphisa ukungqubuzana kunye nokunciphisa ukudonsa. Oku kunceda ukwenza umsebenzi oncomekayo wokomba, ukunciphisa ukunxiba kwisixhobo sokomba, kunye nokwandisa ubomi besixhobo.
5. Ukucocwa kwemingxuma ephuculweyo: Ngokunyusa i-viscosity kunye nokuthwala umthamo we-drilling fluid, i-PAC iququzelela ukukhutshwa kwezinto ezisikiweyo kunye ne-debris kumthombo womthombo, ukuphucula ukucocwa kwemingxuma kunye nokunciphisa umngcipheko wombhobho obambekayo.
6. 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.
7. 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.

Isishwankathelo, i-cellulose ye-polyanionic iyinxalenye ebalulekileyo ye-oyile yokugaya i-oyile, ibonelela nge-viscosification, ukulawula ukulahleka kwamanzi, ukuguqulwa kwe-rheology, kunye nezinye iimpawu ezibalulekileyo zokuqinisekisa ukusebenza ngokufanelekileyo kunye nempumelelo yokugaya kwi-oyile kunye negesi yegesi. Ukuthembeka kwayo, ukusebenza, kunye nokuhambelana kokusingqongileyo kuyenza ibe lukhetho olukhethiweyo lokuphucula ukusebenza kolwelo kunye nokuzinza kwe-wellbore.
