Ukusetyenziswa kwePAC Kokwembiwa kunye nokuTshina kodaka lweOyile

I-Polyanionic cellulose (PAC) isetyenziswa ngokubanzi kwinkqubo yokomba kunye nokutshona kakuhle kodaka lweoyile ngenxa yeempawu zayo ezintle kunye nokusebenza. Nazi ezinye zezicelo eziphambili zePAC kolu shishino:

1. Ukulawulwa kweViscosity: I-PAC isetyenziswa njenge-rheology modifier kwi-drilling fluids ukulawula i-viscosity kunye nokugcina iimpawu ezifanelekileyo zolwelo. Inceda ukulawula ukuziphatha kokuhamba kodaka lokugaya, ukuqinisekisa i-viscosity efanelekileyo yokusebenza ngokufanelekileyo. I-PAC isebenza ngokukodwa kwiindawo zokushisa eziphezulu kunye noxinzelelo oluphezulu apho i-viscosity ezinzileyo ibalulekile kuzinzo lwe-wellbore kunye nokucoca imingxuma.
2. Ukulawulwa kwelahleko yolwelo: I-PAC isebenza njenge-arhente yokulawula ilahleko yolwelo, yenza ikeyiki ebhityileyo, engagxumekiyo yokucoca eludongeni lomthombo ukuthintela ukulahleka kolwelo olugqithisileyo ekubunjweni kwayo. Oku kunceda ukugcina ingqibelelo ye-wellbore, ukulawula umonakalo wokwakheka, kunye nokunciphisa uhlaselo lolwelo lokubunjwa. Ulwelo lokomba olusekwe kwiPAC lubonelela ngolawulo lokucoca oluphuculweyo, lunciphisa umngcipheko wokuncamathela ngokwahlukileyo kunye nemiba elahlekileyo yokujikeleza.
3. I-Shale Inhibition: I-PAC inqanda ukudumba kunye nokusasazeka kwe-shale ngokwenza i-coating ekhuselayo kwi-shale surfaces, ukuthintela ukukhutshwa kwamanzi kunye nokwahlukana kwamasuntswana e-shale. Oku kunceda ukuzinzisa ukwakheka kwe-shale, ukunciphisa ukungazinzi kwequla, kunye nokunciphisa ubungozi bokomba obunjengombhobho obambekayo kunye nokuwa kwequla. I-PAC-based drilling fluids iyasebenza kwimisebenzi yokwemba esekwe ngamanzi kunye ne-oyile.
4. Ukunqunyanyiswa kunye noThutho lwe-Cuttings: I-PAC iphucula ukunqunyanyiswa kunye nokuthuthwa kwezinto ezisikiweyo kulwelo lokomba, ukuthintela ukuhla kwazo kunye nokuqokelelana emazantsi omthombo. Oku kuququzelela ukususwa ngokufanelekileyo kwezinto eziqinileyo ezigrunjiweyo ukusuka kumthombo, ukukhuthaza ukucocwa kwemingxuma engcono kunye nokuthintela imiqobo kwisixhobo sokomba. I-PAC iphucula amandla okuthwala kunye nokusebenza kakuhle kokujikeleza kolwelo lokomba, okukhokelela ekusebenzeni ngokutyibilika kokomba kunye nokuphucula ukusebenza ngokubanzi.
5. Iqondo lobushushu kunye noZinzo lweSalinity: I-PAC ibonisa uzinzo olubalaseleyo kuluhlu olubanzi lwamaqondo obushushu kunye namanqanaba etyuwa adityanelwe kwimisebenzi yokomba yeoli nerhasi. Igcina ukusebenza kwayo kunye nokusebenza kwayo kwiindawo zokomba ezinzima, kubandakanywa ukugrumba kwamanzi anzulu, ukugrumba ngaphandle kwe-offshore, kunye nezicelo zokwemba ezingaqhelekanga. I-PAC inceda ukuthomalalisa ukuthotywa kolwelo kunye nokugcina iipropati zolwelo olungaguquguqukiyo phantsi kweemeko ezinzima.
6. Ukuthotyelwa kokusiNgqongileyo: I-PAC ihambelana nokusingqongileyo kwaye iyakwazi ukubola, nto leyo eyenza ibe lolona khetho lukhethwayo ukugrumba imixube yolwelo kwiindawo ezinobume bendalo. Ihambelana nemigaqo kunye nemigangatho yokusingqongileyo, ukunciphisa impembelelo yemisebenzi yokomba kwi-ecosystem engqongileyo. I-PAC-based drilling fluids inikezela ngesisombululo esizinzileyo kwi-oyile kunye negesi yokuhlola kunye nemisebenzi yokuvelisa.

i-polyanionic cellulose (PAC) idlala indima ebalulekileyo kwinkqubo yokomba kunye nokutshona kwequla lodaka lwe-oyile ngokubonelela ngolawulo lwe-viscosity, ukulawulwa kwelahleko yolwelo, uthintelo lwe-shale, ukunqunyanyiswa, ukuthuthwa kokusika, ubushushu kunye nokuzinza kwetyuwa, kunye nokuthotyelwa kokusingqongileyo. Ukuguquguquka kwayo kunye nokusebenza kwayo kuyenza ibe yinto eyongeziweyo eyongeziweyo kwimiqulu ye-drilling fluid, igalelo ekusebenzeni okukhuselekileyo, okusebenzayo, kunye neendleko ezisebenzayo zokomba kwishishini leoli kunye negesi.
