STEAM PULSE PRESSURE GENERATOR Russian patent published in 2021 - IPC E21B43/25 E21B43/24 E21B36/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry, in particular to devices for increasing the productivity of wells by processing the bottom-hole formation zone (BHZ). The steam-pulse pressure generator for oil well treatment includes a sealed housing with a transition device and a steam kinetic chamber, with a high-energy non-detonating fuel mixture and a combustion initiation system. At the same time, a calibrated protection unit against depressurization of the main body at the place of its connection with the transition device is included in the structure of the housing and the transition device. The composition of the steam kinetic chamber includes a perforated outer tube, a protective shell and a perforated inner tube serving as a guide that forms the movement of the melt in vertical and inclined wells along its central axis. In this case, the protective shell is located between the perforated inner and outer pipes.

EFFECT: increase in the efficiency of processing the BHZ.
