Yini i-PAC ku-dring fluid?

Ekuvuthayo uketshezi, i-PAC ibhekisela kwi-polyanionic cellulose, okuyisithako esiyisihluthulelo esisetshenziselwa ukwakheka kodaka. Ukushayela udaka, okwaziwa nangokuthi ukumba uketshezi, kudlala indima ebalulekile kwinqubo yokumba kawoyela negesi. Inika izinhloso ezahlukahlukene, njengokupholisa nokugcoba ukudonsa, ukuhambisa ukusika ngaphezulu, ukuhlinzeka ngozinzo kahle, nokulawula ingcindezi yokwakheka.

I-Polyanionic Cellulose iyi-polymer esolulekayo enamanzi atholakala ku-cellulose, i-polymer yemvelo etholakala ezitshalweni. I-PAC ingezwe ekuvutheni uketshezi ukuze ithuthukise i-Rheology yabo kanye ne-Filtration Control Progreties.

1. Isakhiwo samakhemikhali nezakhiwo zePolyanionic Cellulose (PAC):

I-PAC iyi-polymer eguquliwe elungisiwe ngemali ekhokhwayo ye-anionic.
Isakhiwo saso samakhemikhali senza kube lulane emanzini kalula, kwakha isisombululo esizinzile.
Isimo se-Anionic se-PAC sinikela ngekhono laso lokuxhumana nezinye izinto ku-drive fluid.

2. Ithuthukisiwe Izakhiwo Zerological:

I-PAC isetshenziselwa ukuguqula izakhiwo zesimbozo soketshezi lokumba.
Kuthinta i-viscosity, amandla we-gel kanye nokulawulwa kokulahlekelwa koketshezi.
Ukulawula i-Rheology kubalulekile ukwenza kahle ukusikwa kokuhamba nokugcina ukuqina komthombo.

3. Ukulawulwa kokuhlunga:

Eminye yemisebenzi eyinhloko ye-PAC ukulawula ukulahleka koketshezi ngesikhathi sokumba.
Yakha ikhekhe elincanyana, elingenakufinyeleleka, elingenakufinyeleleka ezindongeni kahle, ukuvimbela ukulahleka koketshezi lokumba ekwakhekeni.
Lokhu kusiza ukugcina izakhiwo ezifiselekayo zodaka lokumba futhi kuvikele ukulimala kokwakheka.

4. Ukuqina kwe-Wellbore:

I-PAC inikela ngokuqina kahle ngokuvimbela uketshezi oluningi kusuka ekungeneni ekwakhekeni.
Kuyasiza ukunciphisa ukuhlukaniswa okwehlukene nezinye izinkinga ezihambisana nokungazinzi kahle.
Ukuqina kwe-Wellbore kubalulekile empumelelweni yemisebenzi yokumba.

5. Izinhlobo ze-PAC kanye nezicelo zazo:

Amabanga ahlukene we-PAC atholakala ngokuya ngesisindo se-molecular kanye nesilinganiso sokufakwa esikhundleni.
Ama-PACS we-Viscosity aphezulu asetshenziswa ngokujwayelekile lapho kudingeka khona isilawuli se-Rheology.
Ngezicelo lapho ukulawulwa kwemali yokulahleka kwe-fluid kuyinto ebaluleke kakhulu, kungakhethwa i-vivosity ephansi ye-PAC.

6. Ukucatshangelwa Kwezemvelo:

I-PAC ivame ukubhekwa njengengane yemvelo ngoba iyi-biodegradable.
Kwenziwe ukuhlolwa komthelela wezemvelo ukuze kuqinisekiswe ukusetshenziswa okunomthwalo wemfanelo nokulahlwa koketshezi lokumba oluqukethe i-PAC.

7. Ukulawulwa kwekhwalithi nokuhlola:

Izindlela eziqinile zokulawula ikhwalithi ziyasetshenziswa ukuqinisekisa ukusebenza ngempumelelo kwe-PAC ku-Dringing Fluids.
Ukuhlolwa okuhlukahlukene, kufaka phakathi izilinganiso ze-Rheological kanye nokuhlolwa kokulahlekelwa koketshezi, kwenziwa ukuhlola ukusebenza kodaka oluqukethe i-PAC.

8. IZINSELELE NEZIMALI:

Naphezu kokusetshenziswa kwayo okusakazekile, izinselelo ezinjengokuqina okushisayo kanye nokuhambisana nezinye izengezo ezingase ziphakame.
Ukucwaninga okuqhubekayo kanye nokwenziwa okusha kunikezelwe ukuxazulula lezi zinselelo kanye nokwenza ngcono ukusebenza okuphelele kwe-PAC ku-Dring Fluids.

I-Polyanionic Cellulose (PAC) iyingxenye ebalulekile ekuvuthweni kwamanzi uketshezi futhi inikela ekulawulweni kwe-Rheology, ukulawulwa kwe-filtration kanye nokuqina komthombo. Izakhiwo zayo ezihlukile zikwenza kube yisengezo esibalulekile embonini kawoyela negesi, ukudlala indima ebalulekile empumelelweni nasekusebenzeni kahle kokusebenza kokumba.
