Abstract: The invention relates to a device and method for treating the backfilled area of the productive stratum adjacent to the drilling area of oil and gas wells using high pressure pulses. The technological equipment consists of a submersible cylindrical container which is equipped with a high pressure section for accumulating the gaseous working agent, a high pressure one-way electromagnetic valve for dispensing the gaseous agent, a low pressure section where gamma radiation and material solidity detectors and data transmission equipment are located, an intermediate section where at least two one-way nozzles are located, specially arranged radially for injecting the working agent into the areas to be treated, and the technical control and operating equipment.
