Estimating the term…
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.
A device for treating the backfilled area of the productive stratum adjacent to the drilling area of oil and gas wells by means of high pressure pulses, the technological equipment of which consists of a submersible cylindrical container having 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.
A method for treating the backfilled area of the stratum adjacent to the drilling area of the well, comprising the lowering into the well of the high pressure pulse generator and the subsequent treatment con pulses at intervals with high energy in the area to be treated in a consecutive manner from bottom to top by means of the generator stopping precisely in front of the areas, characterized by the creation of impulses previously produced on each chosen part with an energy of 250-400 kJ and the oscillations of the impact wave lasting until being completely dampened and a subsequent treatment by means of generating pulses with an energy of 6-8 kJ and frequency of 10-15 Hz.
