FIELD: downhole systems for fluid production, particularly to provide simultaneous production from several reservoirs.
SUBSTANCE: system comprises casing pipe and flow string arranged inside casing pipe. Two separate isolated chambers are created between casing pipe and flow string. Each isolated chamber is communicated with corresponding productive reservoir by means of perforations and comprises at least one hydraulic machine comprising motor and pump. The pump is connected to flow string and communicated with corresponding isolated chamber. Motor is connected with supply hydraulic line. Hydraulic machines of different isolated chambers may be independently controlled. Motor and pump of at least one hydraulic machine may operate in hydraulic motor regime for pump activation or in motor regime to provide hydraulic machine operation in pump regime for produced fluid direction in flow string regardless of operation mode thereof. Bottomhole hydraulic machine for fluid production is also disclosed.
EFFECT: provision of simultaneous fluid production from different productive reservoirs along with independent production control for different reservoirs.
