An optical positioning monitoring system is disclosed. The system has an optical sensing member disposed on a wellbore pipe, such as the tubing or production casing. When a tool comprising an actuating member acts on the optical sensing member, an optical signal is returnable from the optical sensing member indicating the position of the tool. The optical sensing member may include an optical fiber and/or any known optical sensors. The actuating member can be a force applicator or a heat applicator. Alternatively, the optical sensing member can be located on the tool and the actuating member can be located on the tubing or production casing.
La présente invention concerne un système de contrôle de positionnement optique. Le système comporte un membre de captage optique disposé sur un tuyau de puisage, comme la colonne ou le tubage de production. Lorsqu~un outil comprenant un membre d~activation agit sur le membre de captage optique, un signal optique peut être retourné par le membre de captage optique pour indiquer la position de l~outil. Le membre de captage optique peut comporter une fibre optique et/ou tout autre capteur optique connu. Le membre d~activation peut être un applicateur de force ou de chaleur. Alternativement, le membre de captage optique peut être localisé sur l~outil et le membre d~activation sur la colonne ou le tubage de production.
