FIELD: oil and gas industry.
SUBSTANCE: powder channel pressure generator lowered to the well by means of geophysical cable consists of powder charges made in the form of cylinders with a central channel and with holes made in side surface of powder charge, which are connected between the cover and tray by means of a rope. In upper and lower powder charges there installed are glowing filaments electrically connected to geophysical cable. Holes made in side surface of powder charge are inclined towards geophysical cable, and angle between central axis of powder charge and axis of hole in side surface of powder charge is less than 90°.
EFFECT: improving efficiency of action on oil-water formations of solid fuel combustion products; improving installation accuracy of the device at the selected treatment interval; preventing the displacement of powder pressure generator after it is activated.
