CMC inoshandisa muPetroleum uye Oiri Drilling Indasitiri

Carboxymethylcellulose (CMC) inoshandiswa zvakanyanya muindasitiri yepetroleum neoiri yekuchera mashandisirwo akasiyana siyana nekuda kweiyo yakasarudzika zvivakwa sepolymer inonyungudika nemvura. Inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa muzvirimwa, kuburikidza nemakemikari ekuchinja maitiro anounza mapoka ecarboxymethyl. CMC inoshandirwa mumabasa ekuchera pamahombekombe uye kunze kwenyika. Heano akati wandei mashandisirwo akakosha eCMC muindasitiri yepetroleum neoiri yekuchera:

1. Drilling Fluid Additive:
   • CMC inowanzoshandiswa sechinhu chinowedzera chekuwedzera mumvura yekuchera. Inoshanda zvinangwa zvakawanda, kusanganisira:
     • Viscosifier: CMC inowedzera viscosity yemvura yekuchera, ichipa iyo inodiwa lubrication uye kumiswa kwekucheka.
     • Fluid Loss Control: CMC inobatsira kudzora kurasikirwa kwemvura mukuumbwa, kuve nechokwadi kugadzikana kwetsime.
     • Rheology Modifier: CMC inoita senge rheology modifier, ichipesvedzera kuyerera kwemvura yekuchera pasi pemamiriro akasiyana.
2. Suspension Agent:
   • Muzvinwiwa zvekuchera, CMC inoshanda semumiririri wekumiswa, kudzivirira zvimedu zvakasimba, zvakadai sekucheka zvakachekwa, kubva pakugara pasi petsime. Izvi zvinobatsira kuchera zvakanaka uye kubviswa kwekucheka kubva muchibhorani.
3. Lubricant uye Friction Reducer:
   • CMC inopa lubrication uye inoshanda senge inoderedza kukwesha mumvura yekuchera. Izvi zvakakosha mukuderedza kupokana pakati pechibhorani nechibhorani, kuderedza kusakara pamidziyo yekuchera uye kuwedzera kuchera.
4. Borehole Kudzikamiswa:
   • CMC inobatsira kudzikamisa tsime nekudzivirira kudonha kwemaumbirwo akacherwa. Iyo inoumba chivharo chekudzivirira pamadziro etsime, kusimbisa kugadzikana panguva yekuchera mabasa.
5. Cement Slurry Additive:
   • CMC inoshandiswa sekuwedzera mune simende slurries yekuisa mafuta mutsime simende. Inovandudza rheological properties ye simenti slurry, kuve nechokwadi chekuisa kwakakodzera uye kudzivirira kuparadzaniswa kwezvikamu zvesimende.
6. Kuwedzerwa Mafuta Kudzoreredza (EOR):
   • Mukusimudzira mafuta ekudzoreredza maitiro, CMC inogona kushandiswa senge yekufambisa inodzora mumiriri. Inobatsira kuvandudza kugona kwekutamisa kwemvura yakajairwa, kufambisa kudzoreredzwa kwemamwe mafuta kubva mumadhiza.
7. Fluid Viscosity Control:
   • CMC inoshandiswa kudzora viscosity yezvinwiwa zvekuchera, kuve nechokwadi chemhando yepamusoro yezvinwiwa pasi pemamiriro akasiyana ekudzika. Izvi zvakakosha pakuchengetedza kudhirowa kwakanaka uye kugadzikana kwetsime.
8. Sefa Cake Control:
   • CMC inobatsira kudzora kuumbwa kwemasefa makeke pamadziro etsime panguva yekuchera. Inobatsira pakusikwa kwekeke yakagadzikana uye inodzoreka yekusefa, kudzivirira kurasikirwa kwemvura yakawandisa uye kuchengetedza wellbore kuperera.
9. Reservoir Drilling Fluids:
   • Mukuchera dhamu, CMC inoshandiswa mukuchera zvinwiwa kugadzirisa matambudziko ane chekuita nemamiriro emvura. Inobatsira mukuchengetedza kugadzikana kwetsime uye kudzora zvinhu zvemvura.
10. Yakarasika Kutenderera Kwekudzora:
    • CMC inoshandiswa kudzora yakarasika kutenderera nyaya panguva yekuchera. Inobatsira kuvhara uye kubhuroka magaka mukuumbwa, kudzivirira kurasikirwa kwemvura yekuchera munzvimbo dzine porous kana dzakatsemuka.
11. Well Stimulation Fluids:
    • CMC inogona kushandiswa mutsime yekukurudzira zvinwiwa kuwedzera fluid viscosity uye kumisa vanosimudzira panguva yehydraulic fracturing operations.

Muchidimbu, carboxymethylcellulose (CMC) inoita basa rakakosha muindasitiri yekuchera peturu neoiri, ichibatsira mukubudirira, kugadzikana, uye kuchengetedzeka kwemabasa ekuchera. Zvimiro zvaro zvakasiyana-siyana zvinoita kuti ive yekuwedzera yakakosha mukuchera zvinwiwa uye simende slurries, kugadzirisa matambudziko akasiyana anosanganikwa nawo mukutsvagisa uye kubviswa kwemafuta uye gasi zviwanikwa.
