Electric power supply apparatus for use downhole
Abstract
A submersible electric power supply device (100A) has a high-pressure flux source (102 '¿and a low-pressure outlet zone / l04), each of which lies at least partially in the device (100A.) A fluid-driven motor (ClOb) generates mechanical rotational energy and is fluid-driven. from the source (l02 / through the motor to the discharge zone 'l04; an electrical generator (' l18 'converts the mechanical rotational down energy from the motor;' l06) to electrical energy.
