HEAVY HYDROCARBONS INTRAFORMATIONAL MOLECULAR MODIFICATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC E21B43/24 E21B36/00 

FIELD: oil and gas industry.

SUBSTANCE: method comprises forming on the well surface, using a ground supercritical water generator, of working fluid saturated with nanoscale catalyst in the form of water in the supercritical state, and its subsequent delivery to the tubing at the bottomhole in the subpacker low pressure zone that is isolated by a packer. Thus the working agent in the form of supercritical water, saturated with nanoscale catalyst, flows out through the nozzle at the bottomhole in the subpacker low pressure zone where it is transformed into the high speed working agent saturated with nanoscale catalyst in the form of superheated steam with a high degree of overheating. The method implementing device comprises a container with water, a water supply pump and a heater, the output of which is connected to the tubing column mounted in the injection well, a packer set above the producing formation, and a nozzle at the tubing bottom. In this case, the water supply pump intake is connected to the nanoscale catalyst feed pipeline, the other end of which is connected through a catalyst pump with a catalyst tank.

EFFECT: increased efficiency of intraformational catalytic aquathermolysis.
