DEVICE FOR IN-SITU BURNING Russian patent published in 2020 - IPC E21B43/243 

FIELD: chemistry.

SUBSTANCE: invention relates to apparatus for extracting a mixture of hydrocarbons, in particular a mixture of heavy hydrocarbons, from an underground formation by in-situ combustion. Device for in-situ burning comprises an aluminium chip shredder, a separator and a temperature sensor placed in the well, according to the readings of which portions of the dispenser mixture are supplied. Crusher of aluminium chips is sequentially connected to vibration screen for separation of large chips. Separator is connected to the mixer made in the form of a saturator connected to the dispenser. At that, the injector of aluminium chips consists of a batcher including a chip receiver having in the upper part a cover with a hinge and a discharge flexible hose located in the lower part.

EFFECT: technical result is higher uniformity of coverage of formation by burning, reduced viscosity of oil in formation and reduced air consumption.
