OPTICAL SENSOR FOR MEASURING DOWNHOLE INGRESS OF DEBRIS |
摘要 |
An optical sensing member within the anullus zone of a well is disclosed, which sensing member determines the level of debris in the well. When debris accumulates within the anullus zone, said sensing member returns a signal indicative of the level of such debris within the zone. The optical sensing member may include an optical fiber and/or any known optical sensors configured to determine strain, pressure, shape, force, and/or temperature. |
