Non-water based drilling fluid recycling technology
By recycling the treatment agent system and purifying centrifugal separation technology, the low-gravity solids content in non-water drilling fluid is effectively reduced, the recycling efficiency of drilling fluid is improved, and costs are effectively saved.
Selective flocculation effect on low-gravity solids; Reduce the viscosity of drilling fluid and improve the compatibility limit of low-gravity solids;
Effectively reduce the content of low-gravity solids in non-water drilling fluids; Improve the recycling efficiency of nnon-water drilling fluid;
Item | Technical Parameters | ||
Treatment capacity | 5 m³/h | ||
Installed power | 130 kW | ||
Treatment effect | Density of feed≤1.35g/cm³,density after processing≤1.15g/cm³ | ||
Occupied area | 30m2 |
Non-water drilling fluid regeneration treatment technology
Through the deep integration of synergistic catalysts to promote rapid oil phase separation and efficient multi-stage thin-layer desorption technology, the complete separation of solid and liquid in Non-water drilling fluids has been achieved. The separated oil is treated with oil purification agents to remove harmful components, resulting in high-quality recovered oil that meets the requirements for drilling fluids preparation.
High evaporation efficiency, small footprint; Chemical action promotes better separation of oil-water from solid phase; Directional and efficient removal of odors from recovered oil;high-quality recovered oil that meets the requirements for drilling fluids preparation
