Chii chinonzi CMC muDrilling Mud

Carboxymethyl cellulose (CMC) chinhu chakajairika chekuwedzera chinoshandiswa mukuchera madhaka maumbirwo muindasitiri yeoiri negasi.Kuchera madhaka, kunozivikanwawo semvura yekuchera, inoita mabasa akati wandei akakosha panguva yekuchera, anosanganisira kutonhodza nekuzora chibhorani, kutakura zvicherwa zvekuchera pamusoro, kuchengetedza kugadzikana kwetsime, uye kudzivirira kubuda.CMC inoita basa rakakosha mukuzadzisa zvinangwa izvi kuburikidza neayo akasiyana zvivakwa uye mabasa mukati medhaka rekuchera:

1. Viscosity Control: CMC inoita seye rheology modifier mukuchera madhaka nekuwedzera viscosity yayo.Izvi zvinobatsira kuchengetedza zvinodiwa zvinoyerera zvevhu, kuve nechokwadi kuti zvinobudirira kutakura drill cuttings kumusoro uye inopa rubatsiro rwakakwana kumadziro etsime.Kudzora viscosity kwakakosha mukudzivirira nyaya dzakadai sekurasikirwa kwemvura, kusagadzikana kwetsime, uye kusiyana kunamatira.
2. Fluid Loss Control: CMC inoumba keke rakatetepa, risingapindiki resefa pamadziro etsime, rinobatsira kuderedza kurasikirwa kwemvura mukuumbwa.Izvi zvakanyanya kukosha mukudzivirira kukuvadzwa kwekuumbwa, kuchengetedza kutendeseka, uye kuderedza njodzi yekurasika kutenderera, uko madhaka ekuchera anotizira munzvimbo dzinopinda zvakanyanya.
3. Kumiswa kweDrill Cuttings: CMC inobatsira mukumiswa kwekucheka kwekucheka mukati medhaka rekuchera, kudzivirira kuti isagadzika pazasi petsime.Izvi zvinogonesa kubviswa kwakanaka kwekucheka kubva mugomba uye kunobatsira kuchengetedza kudhirowa kwakanaka uye kubudirira.
4. Kuchenesa Gomba: Nekuwedzera viscosity yedhaka rekuchera, CMC inovandudza kutakura kwayo uye kugona kwekuchenesa gomba.Izvi zvinobatsira kuona kuti madhiri ekucheka anotakurwa zvakanaka kuenda kumusoro, kudzivirira kuti asaunganire pasi pegomba uye kukanganisa kufambira mberi kwekuchera.
5. Lubrication: CMC inogona kuita semafuta ekuchera madhaka maumbirwo, ichideredza kupokana pakati petambo yekuchera nemadziro etsime.Izvi zvinobatsira kuderedza torque uye kudhonza, kuvandudza kuchera, uye kuwedzera hupenyu hwemidziyo yekuchera.
6. Temperature Kugadzikana: CMC inoratidzira yakanaka tembiricha kugadzikana, kuchengetedza viscosity yayo uye kuita munzvimbo dzakasiyana siyana dzekudzika.Izvi zvinoita kuti ive yakakodzera kushandiswa mune zvese zvakajairwa uye yakakwirira-tembiricha yekuchera mabasa.

CMC ndeyekuwedzera kune zvakasiyana-siyana inoita basa rakakosha mukugadzira madhaka ekuchera, kubatsira kukwenenzvera kuita kwekuchera, kuchengetedza kugadzikana kwemutsime, uye kuve nechokwadi chekuchengetedza uye kushanda zvakanaka kwekuchera muindasitiri yemafuta negasi.
