POWDER GENERATOR OF PRESSURE AND METHOD FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC E21B43/18 E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: powder generator consists of powder charges connected via cable between cover and tray. Not less than one powder charge contains glowing spiral electrically connected to geophysical cable. According to the invention there is an upper packer installed on geophysical cable above the powder charges that is done in a form of elastic membrane with powder charge of upper packer, electrical spiral of upper packer and additional powder charge with upper packer detonator. Below the powder charges there is a lower packer done in a form of elastic membrane with powder charge of lower packer, electrical glowing spiral of lower packer and additional powder charge with lower packer detonator. Wire thickness and its material of upper and lower packer glowing are made the same, but different from glowing spiral of powder charge. According to invention the method consists in the use of above powder generator of pressure.

EFFECT: increase of formation influence efficiency, increase of pressure on this formation in treatment interval, prevention of product blow-out from the well.
