Ukusetshenziswa kweCMC e-oilfieldImboni

I-Carboxymethyl Cellulose (CMC) isetshenziswa kabanzi embonini yamafutha ezinceku ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile kanye nokusebenza. Isebenza njengesengezo esiguquguqukayo ku-drive fluids, uketshezi lokuqeda, kanye nama-slurries okulinyazayo, phakathi kwezinye izinhlelo zokusebenza. Nazi ezinye izindleko ezijwayelekile ze-CMC embonini yamafutha:

1. Ukudonsa uketshezi:

• I-VisCosifier: I-CMC isetshenziswa njenge-ejenti esuselwa ekuvuthweni kwamanzi asuselwa emanzini ukuze ikhuphule ukubonakala futhi ithuthukise umthamo wokuphatha uketshezi. Kuyasiza ukugcina ukuqina kwe-Wellbore, kumise ukusika, nokulawula ukulahleka koketshezi ngesikhathi sokumba.
• Ukulawulwa kokulahlekelwa koketshezi: I-CMC isebenza njenge-ejenti yokulawula ukulahleka koketshezi ekwakheni ikhekhe elincanyana, elingenakufinyeleleka odongeni lwe-Wellbore, ukuvimbela ukulahleka koketshezi ngokweqile ekwakhiweni.
• I-Shale Evition: I-CMC isiza ukuvimbela ukuvuvukala kwama-shale nokuhlakazeka ngenhlamvu ye-shale kanye nokuvimbela i-hydration yezinhlayiya zobumba, ukunciphisa ingozi yokungazinzi kahle kwe-Wellbore kanye nezehlakalo zepayipi.
• Ukuqina kobumba: I-CMC iyazinza amaminerali wobumba esebenzayo ekuvutheni uketshezi, ukuvimba ukuvuvukala kobumba nokufuduka, kanye nokwenza ngcono ukumba kwezidakamizwa ekwakhekeni okucebile ngodaka.

2. Ukuqeda uketshezi:

• Ukulawulwa kokulahlekelwa koketshezi: I-CMC yengezwa ku-fluids ukuqeda ukulawula ukulahleka koketshezi ekwakhekeni ngesikhathi sokuqedwa kahle kanye nokusebenza kokudla. Kuyasiza ukugcina ubuqotho bokwakha futhi kuvimbela ukulimala kokwakheka.
• Ukuqiniswa kwe-Shale: I-CMC isiza ekuqiniseni ama-shales kanye nokuvimbela i-shale hydration kanye nokuvuvukala ngesikhathi sokuqeda, ukunciphisa ukungazinzi kahle kanye nokwenza ngcono ukukhiqiza kahle.
• Ukwakheka kwekhekhe le-Filter: I-CMC ikhuthaza ikhekhe le-Uniform, lokuhlunga elingenakufinyeleleka ekwakhekeni kobuso, ukunciphisa ingcindezi ehlukile kanye nokufuduka kwamanzi ekwakhekeni.

3. Ukuhlaziya okuyisisekelo:

• Isengezo sokulahleka kwe-Fluid: I-CMC isebenza njenge-fluid ukulahleka okunezelile ekunciphiseni ukuncipha ukuze kunciphise ukulahleka koketshezi kube amafomu avumelekile futhi kuthuthukiswe ukusebenza kahle komakhale. Kuyasiza ekuqinisekiseni ukwehlukaniswa okulungile kwe-zonal kanye nokwemaka.
• I-ejenti yokuqina: I-CMC isebenza njenge-ejenti yokuqina ezihlahleni zikasimende, ukuhlinzeka ngokulawulwa kwe-viscosity kanye nokwenza ngcono ukuncipha kanye nokumiswa kwezimpawu zokwenza usimende ngesikhathi sokubekwa.
• I-Rheelogy Modifier: I-CMC iguqula i-Rheology of Cement Slurries, Ukwenza ngcono ukugeleza kwezakhiwo, ukumelana kwe-SAG, kanye nokuqina ngaphansi kwezimo zephansi.

4. Ukuvuselela amafutha athuthukisiwe (eor):

• Izikhukhula zamanzi: I-CMC isetshenziswa emisebenzini yezikhukhula zamanzi ukuze ithuthukise ukusebenza kahle futhi ithuthukise ukululama kawoyela kusuka kuma-reservoors. Kwenyusa ukubonakala kwamanzi okujova, ukwenza ngcono ukulawulwa kokuhamba kanye nokusebenza kahle.
• Izikhukhula ze-Polymer: Ku-Polymer Flathering application, i-CMC iqashwa njenge-ejenti yokulawula ukuhamba ukuze ithuthukise ukuvumelana kwama-polmer ajoyine futhi yandise ukukhuphuka kwamanzi okususa uketshezi.

5. Ukuphupha uketshezi:

• I-Pluid Viscosifier: I-CMC isetshenziswa njenge-ejenti ye-viscosifing e-hydraulic ukuphupha uketshezi ukwandisa i-fluid viscosity kanye nomthamo ohambisanayo. Kuyasiza ukudala nokugcina ukuphazamiseka ekwakhekeni nasekuthuthukiseni ukuthuthwa kanye nokubekwa.
• Isithuthukisi Sokuvuselelwa Kwe-Fracture: I-AIDS ye-CMC ekugcineni i-Proppant Pack Confinity kanye nokuphazamiseka ngokunciphisa ukuvuza koketshezi ekwakhekeni nasekuvimbeleni ukuzinza kwe-proppant.

Ngokufigqiwe,carboxymethyl cellulose(CMC) idlala indima ebalulekile ezinhlelweni ezahlukahlukene ngaphakathi kwe-Oilfield Facto, kufaka phakathi uketshezi lokumba, ukuqeda uketshezi, ukulungiswa kokopha, ukulungiswa kwamafutha, nokubuyiselwa okuthuthukisiwe. Ukuguquguquka kwayo njengo-ejenti wokulawula ukulahleka koketshezi, i-viscosifier, i-shadole inhibitor, kanye ne-rheology modifier kwenza kube yisengezo esisemqoka ekuqinisekiseni ukusebenza kahle nokuphumelelayo kwamafutha okusebenza.
