BOTTOMHOLE CATALYTIC ASSEMBLY FOR THERMAL IMPACT ON FORMATIONS CONTAINING HYDROCARBONS AND SOLID ORGANIC SUBSTANCES Russian patent published in 2015 - IPC E21B36/00 E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: device for thermal impact on the formations containing hydrocarbons (HC) and solid organic substances (SOS) is characterised by that it is the bottomhole catalytic assembly (BCA). BCA comprises the bottomhole catalytic reactor, the heat exchanger, the catalyst pre-heating unit in the bottomhole catalytic reactor, a flow-through packer with elastic elements, the product supply pipeline for pumping into the bottomhole catalytic reactor of methane and air mix, the product supply pipeline for pumping into the flow-through packer and water into the bottomhole, and also the product supply pipeline for pumping of furnace gases from the bottomhole to its day surface. Thus the bottomhole catalytic reactor, the heat exchanger and the catalyst pre-heating unit in the bottomhole catalytic reactor form the bottomhole indirect catalytic steam generator (BHICSG).

EFFECT: increase of NC recovery factor, complex development of resource potential of oil-bearing shale layers, improvement of efficiency of development of heavy and difficult for recovery stocks of HC, occurred at considerable depths.
