METHOD OF HIGH-VISCOSITY OIL POOL DEVELOPMENT WITH USAGE OF IN-SITU COMBUSTION Russian patent published in 2010 - IPC E21B43/243 

FIELD: oil-and-gas production.

SUBSTANCE: method includes pumping of oxidising agent through injection wells, arrangement of in-situ combustion and withdrawal of products through producing wells. Into injection wells there is additionally injected in parallel to oxidising agent fuel. In the capacity of producing there are used wells with horizontal bore in suspended part of stratum, and in the capacity of injection wells - vertical, which are located at specific distance from end part of horizontal bore and from each other, excluding cracking of fuel or oxidising agents into other wells in the direction of continuation of horizontal bore. Fuel is pumped through vertical wells, close to horizontal bore, and oxidising agent-through remote. Bottom-hole pressure of fuel is implemented at pressure higher than pressure of opening of vertical cracks, and oxidising agent - higher than pressure of pumping fuel.

EFFECT: effectiveness increase of process displacement of high-viscosity oil by means of increasing of reservoir coverage of impact ensured sequential treatment of all stratum with holding of high permeability.
