FIELD: oil industry, particularly for separate injecting two different reagents in disconnected beds.
SUBSTANCE: device has packer and disconnector. Packer body is through in axial direction. Disconnector have valve arranged in disconnector shaft and closed at bottom end. Bottom valve end have decreasing diameter and forms chamber together with disconnector shaft. Chamber communicates with disconnector hollow through radial channels. After packer installation valve for lower bed treatment and cleaning moves downwards, radial disconnector shaft orifices are opened for treating and cleaning upper bed through above orifices.
EFFECT: simplified structure, possibility of simultaneous treating and cleaning two beds.
