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.

摘要： Example methods and apparatus to detect phase separation in downhole fluid sampling operations are disclosed. An example method to detect a phase separation condition of a fluid from a subterranean involves obtaining a sample of the fluid, measuring a first characteristic value of the sample, measuring a second characteristic value of the sample and comparing the first characteristic value to a first reference value associated with a single-phase condition of the fluid to generate a corresponding first comparison result. The example method then compares the second characteristic value to a second reference value associated with the single-phase condition of the fluid to generate a corresponding second comparison result and detects the phase separation condition of the fluid based on the first and second comparison results.
