摘要： An optical inclination sensor is provided having at least one reflective surface and at least two separate optical fibers having ends spaced from a reflective surface. As the reflective surface tilts with respect to a pre-determined reference position the gap lengths between the fiber ends and the reflective surface change and the differences in these gap lengths is used to calculate an angle of inclination with respect to a reference position. The optical inclination sensor can include at least one mass attached to a housing and moveable with respect to the housing as the mass and housing are rotated about one or more axes. Optical strain sensors are disposed a various locations between the mass and housing so that as the mass moves with respect to the housing, each one of the optical strain sensors are placed in compression or tension. The housing can be a generally u-shaped housing having two arms and a base section with the mass disposed within the housing. Alternatively, the housing includes a first beam, and the mass is a second beam arranged generally orthogonal to the first beam and pivotally attached thereto. The optical strain sensors are disposed between the first beam and the second beam. The optical strain sensors are placed in tension or compression as the second beam pivots with respect to the first beam.

摘要： 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.
