Abstract: FIELD: oil industry. 
     SUBSTANCE: method includes mounting on a pipes column, serially in upward direction, of packer with central pass channel, support with passage ports and axial stepped pass channel, wherein it is possible to mount stream pump or blocking insert, and an assembly for attaching or detaching pipes column, this column is lowered into the well and packer is unpacked in zone above productive bed, then stream pump is lowered into well on logging cable with pressurizing assembly mounted in body of the latter, while logging cable is let through pressurizing assembly and pumped environment feeding channel of stream pump, while logging device is fixed at end of logging cable below stream pump, stream pump body is mounted in axial stepped channel of support and logging device is lowered on logging cable into productive bed zone, during descent logging device is used to measure background geophysical parameters of productive bed, after that by means of feeding working liquid along pipes column into nozzle of stream pump a row of depressions in sub-packer well zone is formed, while recording well debits and face pressures, then recording of geophysical parameters of productive bed is performed, while moving logging device during operation of stream pump along the well on logging cable, after that feeding of working liquid into pump nozzle is stopped, pump with logging device is extracted from the well to surface, in axial stepped channel of support a blocking insert is placed while overlapping passage ports of support, and well is launched into operation according to fountain method, and in case of fall of debit blocking insert is removed from support, stream pump is lowered into well on logging cable with logging device at the end of logging cable, stream pump is mounted in axial stepped channel of support, working liquid is fed into nozzle of pump and depression on productive bed is formed in sub-packer space, while in depression mode, examining geophysical parameters of productive bed and bed fluid, while extracting mudding particles via pump from the well together with accumulated liquid substance, then stream pump with logging device is extracted from the well and blocking insert is mounted in axial stepped channel of support with following launch of well into operation according to fountain method, and when flowing ends, blocking insert is removed from support and in axial stepped channel of support a stream pump for extraction of bed fluid is mounted, or pipes column above support is detached, a portion of pipe column above support is extracted to surface and then operation pump is lowered into well on pipe column for extraction of product substance, while connecting pipes column in place of its detaching. Well plant has pipes column with, serially mounted in upward direction, packer with central pass channel, support and assembly for attaching and detaching tubing pipes column, while in support passage ports are made and axial stepped passage channel, wherein it is possible to mount blocking insert with central pass channel or stream pump, while in the body of stream pump following portions are made: channel for feeding working liquid into nozzle, channel for feeding substance pumped from the well and channel for removing mixture of substances, and in body above channel for feeding extracted substance a pass channel connected to the latter is made with a socket for mounting pressurizing assembly and in the latter an axial channel is made with possible letting through it and a channel for feeding extracted substance of logging cable for mounting on it in the well below pump of logging device with its possible displacement along well shaft with operating or disabled pump, channel for extraction of substances mixture is connected to passage ports and through the latter to space surrounding pipes column, channel for feeding working liquid is connected to inner hollow of pipes above stream pump and pass channel of body of stream pump is made with possible mounting therein, with overlapping of pass channel, of device for delivering pump into well and extracting it from the well. 
     EFFECT: higher productiveness.
