Ukusetshenziswa kweI-CMC e-OilfieldImboni

I-Carboxymethyl cellulose (CMC) isetshenziswa kabanzi embonini ye-oilfield ngezicelo ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile nokusebenza kwayo. Isebenza njengesengezo esiguquguqukayo kuketshezi lokumba, uketshezi oluqedayo, nama-slurries osimende, phakathi kwezinye izinhlelo zokusebenza. Nakhu okunye ukusetshenziswa okuvamile kwe-CMC embonini ye-oilfield:

1. Ukugaya Uketshezi:

• I-Viscosifier: I-CMC isetshenziswa njenge-ejenti ye-viscosifying kuketshezi lokumba olusekelwe emanzini ukukhulisa i-viscosity nokuthuthukisa umthamo wokuthwala uketshezi. Isiza ukugcina ukuqina kwe-wellbore, ukumisa ukusikwa, nokulawula ukulahleka koketshezi ngesikhathi sokumba.
• Ukulawula Ukulahleka Kwe-Fluid: I-CMC isebenza njenge-ejenti yokulawula ukulahlekelwa uketshezi ngokwenza ikhekhe lesihlungi elincanyana, elingangeneli odongeni lomthombo, livimbele ukulahlekelwa uketshezi oluningi ekwakhekeni.
• I-Shale Inhibition: I-CMC isiza ukuvimbela ukuvuvukala kwe-shale nokuhlakazeka ngokumboza izindawo ezingaphansi kwe-shale nokuvimbela ukugeleza kwezinhlayiya zobumba, inciphise ubungozi bokungaqini kahle kwe-wellbore kanye nezigameko zamapayipi abambekile.
• Ukuqiniswa Kobumba: I-CMC iqinisa amaminerali obumba asebenzayo oketshezini lokumba, ivimbele ukuvuvuka kobumba nokufuduka, futhi ithuthukise ukusebenza kahle kokumba ekubunjweni okunothe ngobumba.

2. Uketshezi Lokuphothula:

• Ukulawulwa Kokulahleka Kwe-Fluid: I-CMC yengezwa ekuqedeni uketshezi ukulawula ukulahlekelwa uketshezi ekwakhekeni ngesikhathi sokuphothula kahle kanye nokusebenza kokusebenza. Isiza ukugcina ubuqotho bokwakheka futhi ivimbele ukulimala kokwakheka.
• Ukuqina Kwe-Shale: I-CMC isiza ekusimamiseni ama-shale futhi ivimbele ukugeleza kwe-shale kanye nokuvuvukala ngesikhathi sokuphothula, ukunciphisa ukungazinzi kwemithombo yamanzi kanye nokwenza ngcono ukukhiqiza kahle.
• I-Filter Cake Formation: I-CMC ikhuthaza ukwakheka kwekhekhe le-uniform, elingenakunyakaziswa lokuhlunga ebusweni bokubunjwa, ukunciphisa ingcindezi ehlukile kanye nokufuduka koketshezi ekubunjweni.

3. Ama-Slurries okufaka usimende:

• Isengezo Sokulahleka Kwe-Fluid: I-CMC isebenza njengesengezo sokulahlekelwa uketshezi ekufakweni kukasimende ukuze kuncishiswe ukulahlekelwa uketshezi kube ukwakheka okungenekayo futhi kuthuthukise ukusebenza kahle kokubeka usimende. Kuyasiza ukuqinisekisa ukuhlukaniswa okufanele kwendawo kanye nokubopha usimende.
• I-ejenti ejiyayo: I-CMC isebenza njenge-ejenti ejiyayo kumaslurries kasimende, ihlinzeka ngokulawula i-viscosity kanye nokuthuthukisa ukudonsa nokumiswa kwezinhlayiya zikasimende ngesikhathi sokubekwa.
• I-Rheology Modifier: I-CMC ilungisa i-rheology yama-slurries kasimende, ithuthukise izakhiwo zokugeleza, ukumelana nokucwila, nokuzinza ngaphansi kwezimo ze-downhole.

4. Ukutholwa Kawoyela Okuthuthukisiwe (EOR):

• Izikhukhula Zamanzi: I-CMC isetshenziswa emisebenzini yezikhukhula zamanzi ukuthuthukisa ukusebenza kahle kokushanela kanye nokwenza ngcono ukutholakala kukawoyela kumadamu. Yandisa i-viscosity yamanzi omjovo, ithuthukise ukulawulwa kokuhamba kanye nokusebenza kahle kokuhamba.
• I-Polymer Flooding: Kuzicelo zezikhukhula ze-polymer, i-CMC iqashwa njenge-ejenti yokulawula ukuhamba ukuze kuthuthukiswe ukuhambisana kwama-polymer ajovwe futhi kukhuphule ukusebenza kahle kokushanela kokukhipha uketshezi.

5. Uketshezi Oluqhekekayo:

• I-Fluid Viscosifier: I-CMC isetshenziswa njenge-ejenti ye-viscosifying kuketshezi lwe-hydraulic fracturing ukukhulisa i-viscosity yoketshezi kanye nomthamo wokuthwala. Isiza ukudala nokugcina ama-fractures ekubunjweni futhi ithuthukise ukuthutha nokubeka okubalulekile.
• I-Fracture Conductivity Enhancement: I-CMC isiza ekugcineni ubuqotho bephakethe le-propant kanye ne-fracture conductivity ngokunciphisa ukuvuza koketshezi ekubunjweni nasekuvimbeleni ukuzinza kwe-propant.

Ngokufigqiwe,i-carboxymethyl cellulose(CMC) idlala indima ebalulekile ekusetshenzisweni okuhlukahlukene embonini ye-oilfield, okuhlanganisa uketshezi lokumba, uketshezi lokuphothula, ama-slurry osimende, ukutholwa kukawoyela okuthuthukisiwe (EOR), noketshezi oluqhekekayo. Ukuguquguquka kwayo njenge-ejenti yokulawula ukulahlekelwa uketshezi, i-viscosifier, i-shale inhibitor, kanye ne-rheology modifier kuyenza ibe isengezo esibalulekile sokuqinisekisa ukusebenza kahle nangempumelelo kwenkundla kawoyela.
