FIELD: oil and gas industry.
SUBSTANCE: group of inventions is related to cordless well module and the well system comprising it. The module is configured for running in to a casing pipe inside the well, which has inner wall and inner diameter. The cordless well module comprises an electric motor, a pump and drivers to ensure movement of the cordless well module inside the casing pipe and at least one battery pack. At that the module comprises an expandable device having the central part and manufactured so that it may be expanded from the first diameter up to the second one. At that the expandable device has an opening in the central part and turbine interconnected with the above opening in order to transfer fluid for the battery recharging.
EFFECT: increase in operational efficiency of the cordless well module.
