SISTEMA PARA MEDIR UM PARÂMETRO DENTRO DE UM POÇO, MÉTODO PARA MEDIR UM PARÂMETRO DENTRO DE UM POÇO, E MÉTODO PARA COMUNICAR UM PARÂMETRO DENTRO DE UM POÇO

摘要

The invention provides a system for measuring a parameter within a well, made of: a first apparatus comprising a first reel (41) of first wound optic fiber line (or fiber) able to be unwound from the first reel, at least a first sensor (51) able to measure the parameter of the well, wherein an information on said parameter can be transmitted trough the first optic fiber (11); a second apparatus comprising a second reel (40) of second wound optic fiber line able to be unwound from the second reel, an extremity of the second optic fiber (10) being fixed to a reference point; a light transmitter or receiver device (12) linked to the reference point and able to generate or detect a light pulse through the second optic fiber line (10); and means to exchange said light pulse between first (11) and second optic fiber line (10).
