Abstract

Patente de Invenção: "SENSOR DE LASER DE FIBRA PARAMEDIR PRESSõES DIFERENCIAIS E VELOCIDADES DEFLUXO". A presente invenção se relaciona a um sensor depressão diferencial de laser de fibra 1 o qual é adequado emparticular para a medição de pressões diferenciais e velocidadesde fluxo v~ 1~ dentro dos poços de perfuração de petróleo. Olaser de fibra (2) de acordo com a invenção compreende doissegmentos de fibra de sensor 5a,5b sujeitos a diferentes cargas depressão, em cujos segmentos uma birrefringência proporcional àpressão diferencial <30>p = p~ 1~,-p~ 2~,e conseq³entemente auma freq³ência de batida, é induzida entre os modos depolarização ou os modos espaciais no laser de fibra 2. Modalidadesexemplares com as fibras monomodo polarimétricas 5a, 5b e/oucom as fibras de dois modos elípticas 5a, 5b são especificadas.Mais ainda, os alojamentos de sensores de câmaras múltiplasresistentes à pressão 25 e as disposições multiplex de divisão decomprimento de onda são descritos para o sensor de pressão delaser de fibra 1. Uma vantagem é que o sinal de pressão écodificado em comprimento de onda e assim altamente insensívelà interferência. Ele pode ser lido diretamente em fibra ótica sobregrandes distâncias entre um cabeçote de sensor passivamenteótico 1 e o dispositivo de medição opto-eletrónico 12, 17. Umaaplicação diz respeito à medição de uma velocidade de fluxo v~1~, com a ajuda de um tubo Venturi 32.
