FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry and can be employed for development and exploration of wells and for intensifying of influx. The essence of the invention includes a hydraulic vibrator approaching the next interlayer in an interval of a layer perforation, an active medium supply into it with surface pumping assemblies operated in a alternate mode, withdrawal of the active medium, packer installation, supply of required chemical solution in a chosen mode, pressing the solution into a horizon creating repression, lowering of a working ball for installation in an under packer jet pump and working liquid supply. This liquid is mixed and injected when passing through the under-packer jet pump with horizon liquid, then the well is drained. All changes of bottomhole pressure are registered with apparatus installed in a safety chamber. The working ball of the under-the packer jet pump is lifted and an anchor with connected thereto a depth apparatus is lowered till it lands in an above-the packer jet pump. Working liquid is supplied into annular space to the above-the packer jet pump which generates under pressure in the facility. Then horizon liquid is supplied into above-the packer jet pump in the interval of perforation of a producing horizon; the jet pump injects working liquid in form of a mixed liquid and pumps it out to the surface. At that indicative characteristics and yield ratio of the well are determined. Then operation of the surface pumping assembly is stopped as well as influx from the horizon. The curve of pressure buildup is traced with the depth apparatus.
EFFECT: facilitating development and intensification of production per one trip.
