Well washing truck

The high-pressure oil washing vehicle is a truck-monster, high-pressure water injection well cleaning equipment. It is specifically designed for the complex conditions and high injection pressures found in most domestic oilfields. This wall washing equipment utilities advanced domestic chassis, mature wastewater treatment equipment and processes, and a self-developed pressure reduction system for water injection wells. It enables high-pressure, non-pressure-relief, large-volume well cleaning operations, meeting the requirements of both high-pressure and conventional water injection wells. Additionally, it significantly reduces operator labor intensity and improves operational efficiency.

Product Features

1.Simultaneously applies to advanced technologies: inclined plate oil removal and gas flotation oil removal, enhancing oil removal efficiency.
2.Uses three-phase mixing technology for rapid flocculation, efficiently completing wastewater pre-treatment, thereby reducing the risk of subsequent equipment damage.
3.Adopt a non-pressure-relief well cleaning methods, meeting the high-pressure well area requirements of Chongqing Oilfield.
4.Automated control ensures convenient and fast operation.
5.Effectively solves post-operation liquid accumulation, conserving resources and reducingpollution.
