SISTEMA DE EQUIPAMENTO SUBTERRÂNEO PAR AUSO EM FUROS DE SONDAGEM, MÉTODO PARA OPERAR UM SISTEMA NA SAÍDA DO CONVERSOR DC/DC SUBTERRÂNEO, SISTEMA DE TRANSMISSÃO DE ENERGIA PARA USO COM EQUIPAMENTO SUBTERRÂNEO EM UM FURO DE SONDAGEM

摘要

A power transmission system for use with downhole equipment in a borehole, comprising a power source (12) positioned at the surface providing a DC power supply and a downhole DC/DC converter (16), connected to the power source by a two-conductor cable (14) and which takes the DC voltage supply as an input and provides an output DC supply at a different voltage to the DC power supply for provision to the downhole equipment (18).
