DEVICE FOR SIMULTANEOUS-SEPARATE PUMPING OF REAGENTS INTO WELL Russian patent published in 2009 - IPC E21B43/243 

FIELD: oil and gas production.

SUBSTANCE: invention elates to oil-producing industry, particularly to heating-physico-chemical treatment of bottomhole zone of stratum. Device includes: two pipes for separate pumping of initial components, mixer, solid-fueled heater, consisting fuel coffin with lattice bottom, allowing openings for withdrawal of combustion materials, casing of fuse mechanism, implemented in the form of sleeve, in bottom of which it is opening for air flow for keeping of burning, in which it is valvatecouple and back pressure valve, connected to fuel coffin by means of coupling, container, filled by flammable liquid, which is implemented with ability of actuation under action of cargo dumped from above, and is place inside the casing of fuse mechanism. In casing of fuse mechanism there are openings for passing through it two pipes for separate pumping of initial component, implemented with ability of passage through the fuel coffin and entry through aiming back pressure valve tangential into mixing reactor from above. Mixing reactor corresponds drum, in bottom of which is tray downspout for withdrawal of a product. At the end of it is adjusted valve, connected to fuel coffin by means of coupling.

EFFECT: creation of device, providing implementation of simultaneously-separate pumping of light hydrocarbon and air, with high withdrawal of a reaction product and implementation of mixing on well bottom at arrival into stratum.
