Polyanionic Cellulose muOiri Drilling Fluid

Polyanionic cellulose (PAC) ipolmer inonyungudika nemvura inotorwa kubva muselulosi, iyo inoshandiswa zvakanyanya muindasitiri yemafuta negasi sechinhu chakakosha chemvura yekuchera.Heano mamwe emabasa ePAC mumafuta ekuchera zvinwiwa:

1. Rheology control: PAC inogona kushandiswa se rheology modifier mukuchera zvinwiwa, kudzora viscosity uye kuyerera kwemvura.Inogona kuderedza viscosity yemvura panguva yakaderera shear mitengo, zvichiita kuti zvive nyore kupomba uye kutenderera.Inogonawo kuwedzera viscosity pamitengo yakakwira shear, kuvandudza zvimiro zvekumisa zvemvura.
2. Fluid kurasikirwa kwekudzora: PAC inogona kushandiswa seyekurasikirwa kwemvura yekuwedzera mumvura yekuchera, kuderedza njodzi yekurasikirwa kwemvura mukuumbwa panguva yekuchera.Inogona kugadzira keke rakatetepa uye risingapindiki resefa pamadziro etsime, kudzivirira kupinda kwemvura yekugadzira mutsime.
3. Shale inhibition: PAC inogona kuvharidzira kuzvimba nekupararira kwe shale formations, kudzivirira kudzikamiswa kwemvura yekuchera uye kuderedza njodzi yekusagadzikana kwetsime.
4. Kushivirira munyu: PAC inoshivirira kunzvimbo dzine munyu wakanyanya uye inogona kushandiswa mukuchera zvinwiwa zvine munyu wakawanda nezvimwe zvinosvibisa.
5. Kuenderana nemhoteredzo: PAC inoodza uye ine hushamwari kwezvakatipoteredza, zvichiita kuti ive yakachengeteka uye inogoneka sarudzo yekuchera zvinwiwa.

Pakazere, iyo inoshanda zvimiro zvePAC inoita kuti ive chinhu chakakosha mumafuta ekuchera zvinwiwa, inosimudzira mashandiro avo nekuvandudza kugona kwavo.PAC inowanzoshandiswa mumhando dzakasiyana-siyana dzekuchera, dzakadai semvura-based muds, brine-based muds, uye kupera kwemvura.
