FIELD: methods or apparatus for obtaining oil, gas, water, soluble or meltable materials or a slurry of minerals from wells, particularly perforators and permeators.
SUBSTANCE: method in accordance with the first embodiment involves lowering tool string in well; activating gun perforator, overburden condition providing device, processing liquid supply device and device, which creates local transition overburden condition. Method in accordance with the second embodiment involves taking information concerning fluid outburst characteristics for different well bore types; determining well bore type and processing liquid type for perforation tunnel treatment; selecting flow outburst characteristics; selecting time delay between perforation operation and flow outburst operation and selecting volume of low-pressure chamber for fluid borehole medium. Method in accordance with the third embodiment involves lowering tool string in well; activating tool string section including body with explosive charge arranged in the body; creating orifices in the body to open chamber for borehole media and activating tool string section to provide transition overburden condition. Tool string in accordance with the first embodiment comprises processing liquid supply device, which delivers processing liquid into tunnels, device to provide overburden condition and device to create local transition overburden condition. Tool string in accordance with the second embodiment comprises section with low pressure chamber and explosion means, section to create transition overburden condition and section to supply processing fluid medium in reservoir tunnels.
EFFECT: increased efficiency of reservoir fluid communication with well bore.
