Yakagadzirirwa chaizvo kudzikisa coefficient of friction mune ese emvura-base yekuchera zvinwiwa, izvo zvinodzikisa torque uye kudhonza mutsime.Iine hunhu hwakasiyana hwekunyorova hunodzikisira kugona kweBottom-Hole Assembly (BHA) kubhora, haina mahydrocarbons uye inofambirana nemvura yese-yemvura, kusanganisira mono-/divalent brine fluids.Nekugovera kushoma kune rheological properties yedhaka masisitimu, haina furo uye inogona kuwedzerwa kune dhaka system kuburikidza nemusanganiswa hopper kana yakananga kune yepasi system chero kupi kusingagoneki kunowanikwa.
7-Zvakanakira
1. Inoshanda, yose-chinangwa lubricant yemvura-base madhaka masisitimu
2. Deredzai coefficient of friction iyo inoderedza torque uye kudhonza
3. Haiwedzere rheology kana gel simba
4. Ine yakasarudzika simbi-wetting additives izvo zvinoderedza tsika yekupfava, inonamira shale yekukonzeresa uye BHA balling.
5. Haikonzeri kupupa furo
6. Biodegradable isina mahydrocarbon
7. Kusagadzikana kwekushisa ≤200℃ (BHCT)
