Abstract

The invention relates to the petroleum industry and can be used for increasing the productivity of a well by treating the bottomhole zone thereof using devices containing materials generating gas by combustion. Said invention also makes it possible to increase the efficiency of the bottom zone treatment of carbonate strata. The inventive method for treating a bottomhole zone consists in descending a known device in the well by means of a cable. Said device consists of an air chamber which ends by a reception chamber containing a compound which generates a gas by combustion and consists of a mixture producing hydrochloric acid during the destruction thereof. Afterwards, the combustion of gas-generating compound is carried out, thereby forming heated gaseous products at a high pressure during the treatment. In order to obtain the deeper reaction of the hydrochloric acid with the strata, a process dwell is carried out. The impurities are removed from the bottomhole zone when the air chamber is opened in a predefined time interval. Said invention is characterised in that the gas-generating compound is embodied in the form of a mixture whose each component produces during the destruction thereof a hydrochloric acid containing 40-45 mass % ammonium perchlorate and 55-60 mass % polyvinyl chloride.
