Umthengisi weGolide waseTshayina weCmc Carboxymethyl Cellulose - Polyanionic cellulose (PAC) - Yeyuan
Umboneleli weGolide waseTshayina weCmc Carboxymethyl Cellulose - Polyanionic cellulose (PAC) – Yeyuan Iinkcukacha:
I-Polyanionic cellulose (i-PAC) yi-derivative ye-cellulose e-ether enyibilikayo yamanzi elungiselelwe ngokuguqulwa kweekhemikhali ze-cellulose yendalo. Yi-ether ye-cellulose enyibilikayo ebalulekileyo emanzini. Idla ngokusetyenziswa njengetyuwa yesodium kwaye isetyenziswa kakhulu ekugrumbeni ioyile, ngakumbi amaqula amanzi anetyuwa kunye nokugrumba ioyile ekude nonxweme.
I-PAC-Isicelo kwiPetroleum
1. Imisebenzi yePAC kunye neCMC kwindawo yeoli imi ngolu hlobo lulandelayo:
- Udaka oluqulethe i-PAC kunye ne-CMC lunokwenza udonga lwequla lube lubhityile kwaye lube lukhuni ikeyiki yesihluzi esine-permeability ephantsi kunye nokunciphisa ilahleko yamanzi;
- Emva kokongeza i-PAC kunye ne-CMC eludakeni, i-drilling rig inokufumana amandla okucheba aphantsi okuqala, yenze udaka lube lula ukukhulula igesi esongelwe kuyo, kwaye ilahle ngokukhawuleza inkunkuma emhadini wodaka;
- Njengezinye izinto ezisasazwayo ezinqunyanyisiweyo, ukugrumba udaka kunexesha elithile lobukho, elinokuthi lizinziswe kwaye landiswe ngokongeza iPAC kunye neCMC.
2. I-PAC kunye ne-CMC zinemisebenzi elandelayo egqwesileyo kwisicelo se-oilfield:
- Iqondo eliphezulu lokutshintshwa, ukufana okuhle kokutshintshwa, i-viscosity ephezulu kunye nedosi ephantsi, ukuphucula ngokufanelekileyo inkonzo yodaka;
- Ukuxhathisa okulungileyo kokufuma, ukuxhathisa ityuwa kunye nokuxhathisa i-alkali, ilungele amanzi amatsha, amanzi olwandle kunye nodaka olusekwe ngamanzi ane-brine;
- Ikeyiki yodaka eyenziwe isemgangathweni kwaye izinzile, enokuthi ikwazi ukuzinzisa ngokufanelekileyo isakhiwo somhlaba othambileyo kwaye ithintele ukudilika kodonga lweshaft;
-Ifanelekile kwiinkqubo zodaka ezinolawulo olunzima oluqinileyo kunye noluhlu olubanzi.
3. Iimpawu zokusetyenziswa kwePAC kunye neCMC kwi-oyile yokomba:
- Inamandla aphezulu okulawula ilahleko yamanzi, ngakumbi isinciphisi esisebenzayo sokulahla ulwelo. Ngomlinganiselo ophantsi, unokulawula ukulahleka kwamanzi kwinqanaba eliphezulu ngaphandle kokuchaphazela ezinye iimpawu zodaka;
- Inokumelana nobushushu obulungileyo kunye nokuxhathisa kwetyuwa okugqwesileyo. Isenokuba nobuchule obuhle bokunciphisa ilahleko yamanzi kunye ne-rheology ethile phantsi koxinzelelo oluthile lwetyuwa. I-viscosity iphantse ingatshintshi emva kokuchithwa emanzini anetyuwa. Ilungele ngokukodwa ukugrumba i-offshore kunye namaqula anzulu;
- Iyakwazi ukulawula kakuhle i-rheology yodaka kwaye ine-thixotropy enhle. Ilungele naluphi na udaka olusekelwe emanzini kumanzi amatsha, amanzi olwandle kunye ne-brine egcweleyo;
- Ukongeza, iPAC isetyenziswa njengolwelo lokusamente ukuthintela ulwelo ukuba lungangeni kwimibhobho nakwiziqhekeza;
- Ulwelo lokucoca lokucoca olulungiselelwe ngePAC lunokuxhathisa okulungileyo kwi-2% yesisombululo se-KCl (kufuneka sifakwe xa silungiselela ulwelo lokucoca ukucoca), ukunyibilika okuhle, ukusetyenziswa okufanelekileyo, kunokulungiswa kwisiza, ijeli ekhawulezayo yokwenza isantya kunye nesanti eyomeleleyo ethwele umthamo. Xa isetyenziswe kulwakhiwo olusezantsi lokungena, isiphumo sayo sokucoca isihluzi sigqwesileyo.
