Ko CMC nePAC inoita sei basa muindasitiri yemafuta?

Sodium carboxymethyl cellulose (CMC) uye polyanionic cellulose (PAC) ese ari maviri anoshandiswa zvakanyanya muindasitiri yeoiri, kunyanya mukuchera uye kupedza zvinwiwa. Ivo vanotamba mabasa akakosha nekuda kwekugona kwavo kugadzirisa rheological zvivakwa, kudzora kurasikirwa kwemvura, uye kuwedzera kugadzikana kwe wellbore. Heano mashandisirwo eCMC nePAC muindasitiri yemafuta:

1. Drilling Fluid Additives:
   • CMC nePAC zvinowanzoshandiswa sezvinowedzera mumvura-based drilling zvinwiwa kudzora rheological zvinhu zvakadai viscosity, goho poindi, uye kurasikirwa kwemvura.
   • Ivo vanoita semaviscosifiers, vachiwedzera viscosity yemvura yekuchera kutakura dhiri kuchekwa kumusoro uye kuchengetedza kugadzikana kwetsime.
   • Pamusoro pezvo, ivo vanobatsira kudzora kurasikirwa kwemvura nekugadzira keke rakatetepa, risingapindike resefa pamadziro etsime, kuderedza kurasikirwa kwemvura mumaumbirwo anopinza uye kuchengetedza hydrostatic pressure.
2. Fluid Loss Control:
   • CMC uye PAC inoshanda yekudzora kurasikirwa kwemvura mumidziyo yekuchera. Ivo vanogadzira keke rakatetepa, rinosimba resefa pamadziro emutsime, zvichideredza kupera kwechimiro uye kuderedza kurasikirwa kwemvura mudombo rakatenderedza.
   • Nekudzora kurasikirwa kwemvura, CMC uye PAC inobatsira kuchengetedza kugadzikana kwemutsime, kudzivirira kukuvadzwa kwekuumbwa, uye kukwenenzvera kuchera.
3. Shale Inhibition:
   • Mukuumbwa kwe shale, CMC nePAC zvinobatsira kudzikamisa kuzvimba kwevhu nekupararira, kuderedza njodzi yekusagadzikana kwegomba uye zviitiko zvepombi dzakanamira.
   • Vanoumba chidziviriro chekudzivirira pamusoro pe shale pamusoro, kudzivirira mvura uye ions kubva mukupindirana nemaminerari evhu uye kuderedza kuzvimba uye kupararira maitiro.
4. Fracturing Fluids:
   • CMC uye PAC inoshandiswawo mu hydraulic fracturing (fracking) zvinwiwa kugadzirisa fluid viscosity uye kumisa proppant particles.
   • Ivo vanobatsira kutakura proppant kupinda mukutyoka uye kuchengetedza inodiwa viscosity yeinoshanda propant kuiswa uye fracture conductivity.

sodium carboxymethyl cellulose (CMC) uye polyanionic cellulose (PAC) inoita mabasa akakosha muindasitiri yeoiri nekugadzirisa kuchera uye kupedza zvinwiwa kuti zvinyatsoita, kusimudzira kugadzikana kwetsime, kudzora kurasikirwa kwemvura, uye kudzikisira kukuvadzwa kwekuumbwa. Kugona kwavo kugadzirisa rheological zvivakwa, kurambidza kuzvimba kweshale, uye kumisa zvidimbu zvinosimudzira zvinoita kuti zvive zvakakosha zvekuwedzera mumabasa akasiyana-siyana emafuta.
