摘要： A technique usable with a subterranean well includes deploying a first optical sensor downhole in the subterranean well. The technique includes observing an intensity of backscattered light from the first optical sensor to measure a distribution of a characteristic along a portion of the well. The technique includes deploying a second sensor downhole to measure the characteristic at discreet points within the portion. The second sensor is separate from this first sensor and includes at least one interferometric sensor.

摘要： Methods and apparatus for measuring differential pressure with fiber optic sensor systems are disclosed. The apparatus of the present invention include both monopolar and bipolar sensors, sensors incorporating side-hole fibers, sensors incorporating fibers without side holes, FBGs subjected to transverse strain, and FBGs subjected to longitudinal strain. All of the embodiments utilize FBGs. Two embodiments utilize a piston having oppositely extending rods, each of which is exposed to a different pressure. Seven embodiments utilize one or more silica diaphragms coupled to a silica body and exposed to two pressures. In each of these embodiments, pressure is converted into movement of the piston or diaphragm which is then used to strain the FBG(s). When each FBG is interrogated, the spectral information is indicative of the strain exerted by the piston or diaphragm on the FBG and thus the difference between the two pressures. Tenth and eleventh embodiments provide apparatus and methods of measuring a differential pressure.

摘要： An optical fiber is provided with a Bragg grating formed along a portion of its core and a mechanical structure arranged adjacent to the Bragg grating for amplifying longitudinal strain on the fiber in the vicinity of the grating. The mechanical structure is designed to convert ambient pressure into longitudinal strain on the fiber in the vicinity of the grating and to allow the fiber to pass through the structure so that several pressure measuring apparatus may be arranged along a single optical fiber. An intermediate structure is provided between the fiber and the mechanical structure for minimizing buckling of the fiber. The methods of the invention include converting pressure into longitudinal strain on an optical fiber, amplifying the effect of pressure on the longitudinal strain, measuring pressure by determining the spectral location related to peaks (or minimums) of light reflected from an optical grating subjected to longitudinal strain.
