| Abstract: |
| Chemical demulsification treatment of waste oil-based drilling fluid was studied. The screened best demulsifier SA could recover the mineral oil and the oil recovery rate reached 93%. The optimal demulsification process parameters were determined: adding amount of demulsifier SA is 0.8%, PAC coagulant dosage is 600 mg/L, flocculants PAM dosage is 8 mg/L, and the reaction time is 1 h, temperature is （50±0.5）℃. Harmless treatment of isolated waste water and residue were also conducted |
| Key words: waste oil-based drilling fluid, chemical demulsification, recycling oil, harmless disposal |
