FIELD: oil extractive industry. ^ SUBSTANCE: method includes performing a deep penetration perforation in interval of formation being processed, assembly of unpackaged section charge with auxiliaries by letting hollow composite bar through central channel of charge sections, contracting and packing charge sections tightly with each other, connection of logging cable to electronic block for controlling and registering characteristics of charge operation mode by wires, let through in internal hollow of composite bar, combustion of charge sections in perforation interval, realization of control over charge sections combustion in real time mode and registration of charge operation mode characteristics, such as temperature and pressure in well liquid in processing interval. In accordance to invention, performed further is registration of acceleration of displacement of charge auxiliaries and electronic block towards well axis under effect from compression wave, generated by gas trapped in well liquid during combustion of charge sections. On basis of values of acceleration, gas influx in formation input evaluated as well as difference between gas influx created during combustion of charge sections and gas influx in formation liquid. During comparison of parameters of temperature, pressure, and acceleration of displacement of charge auxiliaries and electronic block towards well axis, efficiency of formation processing is evaluated - realized or not realized local disruption of formation along raise and fall of temperature and pressure. Also performed is repeated processing of bed and registration of processing parameters, on basis of change of parameters of temperature, pressure and acceleration during first processing and repeated processing, change of penetrability in inter-well space of bed and need for more processing of formation are evaluated. Device includes electronic block for controlling and registering characteristics of charge mode operation, connected to lower end of bar, ignition unit power cord, let through hollow bar, and conductor, connecting logging cable to electronic block, including sensors of sleeve locator, temperature and pressure. In accordance to invention, electronic block is provided with accelerometer for registration of acceleration of displacement of its own and of charge auxiliaries along well axis under effect from compression wave from gas in well liquid during combustion of charge sections, and is capable of registration of temperature and pressure with frequency, making it possible to produce gradients thereof for fast processes. ^ EFFECT: possible production of independent parameter during operations, which together with temperature and pressure parameters allows to evaluate effect of formation processing. ^ 2 cl |
