Kugwiritsa NtchitoCMC ku OilfieldMakampani

Carboxymethyl cellulose (CMC) imagwiritsidwa ntchito kwambiri m'makampani opangira mafuta pazinthu zosiyanasiyana chifukwa cha mawonekedwe ake apadera komanso magwiridwe antchito. Imagwira ntchito ngati chowonjezera chosunthika mumadzi obowola, madzi omaliza, ndi ma slurries a simenti, pakati pa ntchito zina. Nazi zina zomwe CMC amagwiritsa ntchito pamakampani opangira mafuta:

1. Kubowola Madzi:

• Viscosifier: CMC imagwiritsidwa ntchito ngati viscosifying agent mumadzi obowola opangidwa ndi madzi kuti awonjezere kukhuthala komanso kupititsa patsogolo mphamvu yonyamula madzi. Zimathandizira kuti chitsime chikhale chokhazikika, kuyimitsa kudula, ndikuwongolera kutaya kwamadzimadzi pobowola.
• Fluid Loss Control: CMC imagwira ntchito ngati chowongolera kutayika kwamadzimadzi ndikupanga keke yopyapyala, yosasunthika pakhoma la chitsime, kuteteza kutayika kwamadzi ambiri pamapangidwe.
• Kuletsa kwa Shale: CMC imathandizira kuletsa kutupa kwa shale ndi kubalalitsidwa mwa kuphimba malo a shale ndikuletsa kuthira kwa tinthu tadongo, kuchepetsa chiwopsezo cha kusakhazikika kwa chitsime ndi zochitika zamapaipi.
• Kukhazikika kwa Dongo: CMC imakhazikika m'madzi amchere mumadzi obowola, kuteteza dongo kutupa ndi kusamuka, ndikuwongolera bwino pakubowola mumipangidwe yokhala ndi dongo.

2. Kumaliza Madzi:

• Fluid Loss Control: CMC imawonjezedwa kumadzi omaliza kuti athe kuwongolera kutaya kwamadzimadzi pamapangidwe pomaliza bwino komanso ntchito yogwirira ntchito. Zimathandiza kusunga umphumphu wa mapangidwe ndikuletsa kuwonongeka kwa mapangidwe.
• Kukhazikika kwa Shale: CMC imathandizira kukhazikika kwa shale ndikuletsa kutsika kwa shale ndi kutupa pakumaliza ntchito, kuchepetsa kusakhazikika kwa chitsime ndikuwongolera zokolola.
• Kupanga Keke Yosefera: CMC imalimbikitsa mapangidwe a yunifolomu, keke ya fyuluta yosasunthika pamapangidwe a nkhope, kuchepetsa kuthamanga kwa kusiyana ndi kusuntha kwamadzimadzi mu mapangidwe.

3. Kumanga Simenti:

• Zowonjezera Kutayika Kwamadzi: CMC imagwira ntchito ngati chowonjezera chamadzimadzi pakumangirira ma slurries kuti achepetse kutayika kwamadzimadzi m'mapangidwe osavuta komanso kupititsa patsogolo kuyika kwa simenti. Zimathandiza kuonetsetsa kuti pamakhala kudzipatula koyenera komanso kumangirira simenti.
• Thickening Agent: CMC imagwira ntchito ngati yokhuthala mu slurries ya simenti, kupereka kuwongolera kukhuthala komanso kupititsa patsogolo kutulutsa ndi kuyimitsidwa kwa tinthu tating'ono ta simenti pakuyika.
• Rheology Modifier: CMC imasintha kamvekedwe ka masimenti a simenti, kuwongolera magwiridwe antchito, kukana kwa sag, komanso kukhazikika pansi pamikhalidwe yotsika.

4. Kubwezeretsanso Mafuta Owonjezera (EOR):

• Kusefukira kwa Madzi: CMC imagwiritsidwa ntchito pakusefukira kwamadzi kuti ipititse patsogolo kuseseratu ndikuwongolera kuchira kwamafuta m'masungidwe. Imawonjezera mamasukidwe amadzi a jakisoni, kuwongolera kayendetsedwe ka kayendetsedwe kake komanso kusamuka bwino.
• Kusefukira kwa Polima: Pogwiritsa ntchito kusefukira kwa polima, CMC imagwiritsidwa ntchito ngati chowongolera kuyenda kuti ipititse patsogolo kulumikizana kwa ma polima obaya ndikuwonjezera kuseseratu kwamadzi ochotsa.

5. Mafuta Ophwanyika:

• Fluid Viscosifier: CMC imagwiritsidwa ntchito ngati viscosifying agent mu hydraulic fracturing fluid kuti iwonjezere kukhuthala kwamadzimadzi komanso mphamvu yonyamula. Zimathandizira kupanga ndikusunga zosweka mu mapangidwe ndikuwonjezera zoyendera ndi kuyika.
• Kupititsa patsogolo kwa Fracture Conductivity: CMC imathandizira kusunga kukhulupirika kwa paketi ndi kuphulika kwa fracture pochepetsa kutulutsa kwamadzimadzi ndikupanga ndikuletsa kukhazikika.

Powombetsa mkota,carboxymethyl cellulose(CMC) imatenga gawo lofunikira pakugwiritsa ntchito zosiyanasiyana m'mafakitale opangira mafuta, kuphatikiza madzi akubowola, madzi omaliza, zopangira simenti, kuchira kwamafuta owonjezera (EOR), ndi madzi ophwanyika. Kusinthasintha kwake monga chowongolera kutayika kwamadzimadzi, viscosifier, shale inhibitor, ndi rheology modifier kumapangitsa kukhala chowonjezera chofunikira pakuwonetsetsa kuti ntchito zamafuta zikuyenda bwino.
