Kushandiswa kweHydroxyethyl Cellulose muOilfield Drilling

Hydroxyethyl cellulose (HEC) ipolymer inonyungudika nemvura inoshandiswa zvakanyanya muindasitiri yemafuta negasi, kunyanya mukuchera.HEC inoshandiswa mukuchera zvinwiwa kuti ipe rheological control uye kudzivirira kurasikirwa kwemvura.Izvi zvinotevera mamwe emamwe mashandisirwo eHEC mukuchera muoiri:

1. Rheology Control: HEC inoshandiswa kudzora rheology yekuchera mvura.Kuwedzerwa kweHEC kunowedzera viscosity yemvura yekuchera, iyo inobatsira kumisa kucheka kwekucheka uye kudzivirira kugadzirisa.Iko viscosity yemvura yekuchera inogonawo kugadziriswa nekusiyana kwehuwandu hweHEC mumvura.
2. Fluid Loss Prevention: HEC inoshandiswa sekuwedzera kurasikirwa kwemvura mumvura yekuchera.Kana yakawedzerwa kumvura yekuchera, HEC inoumba firimu yakaonda pamadziro etsime, iyo inobatsira kudzivirira kurasikirwa kwemvura yekuchera mukuumbwa.
3. Kumiswa kweMasori: HEC inoshanda yekumisa mumiriri yezvimedu zvakasimba mumvura yekuchera.Kuwedzerwa kweHEC kunobatsira kuchengetedza zvakasimba mukumiswa, kudzivirira kubva pakugadzirisa kusvika pasi petsime.
4. Kudzora Kudzora: HEC inoshandiswa sefiltration control agent mukuchera mvura.Kuwedzerwa kweHEC kunobatsira kudzora chiyero icho chidhiraivha chinosefa mukuumbwa, kudzivirira kurasikirwa kwemvura yakakosha yekuchera.

Muchidimbu, Hydroxyethyl cellulose (HEC) inoita basa rakakosha muindasitiri yeoiri negasi seyekuwedzera mvura yekuchera, ichipa rheological control, kudzivirira kurasikirwa kwemvura, kumiswa kwezvakaoma, uye kusefa kutonga.
