摘要： A fiber optic Bragg grating pressure sensor particularly suited for measuring ambient pressure of a fluid includes a pressuring detecting device 12 such as a glass element whose elastic deformation is proportional to applied pressure. An optical fiber 28 with an integral first grating 33 is wrapped at least once around the device and has at least a portion of its length fused to the device 12 such that elastic deformation of the device 12 generates a corresponding axial strain in the fiber 28 and/or the grating 33 and thus a corresponding change of the fiber length and/or characteristic reflectance wavelength of the grating 33. A second grating 35 may be formed near the pressure detecting device 12 so as to sense ambient temperature but not be affected by deformation of the device 12 for temperature compensation. Also, the fiber 28 may have more than one grating or be doped at least between a pair of gratings 160,162, to form a fiber laser or a DFB fiber laser which lasing wavelength changes with changing pressure.

摘要： A Bourdon tube pressure gauge is mounted for sensing the pressure of a system. The Bourdon tube is connected to at least one optical strain sensor mounted to be strained by movement of the Bourdon tube such that when the Bourdon tube is exposed to the pressure of the system, movement of the tube in response to system pressure causes a strain in the optical sensor. The optical sensor is responsive to the strain and to an input optical signal for providing a strain optical signal which is directly proportional to the pressure. A reference or temperature compensation optical sensor is isolated from the strain associated with the pressure of the system and is responsive to temperature of the system for causing a temperature-induced strain. The reference optical sensor is responsive to the temperature induced strain and the input optical signal for providing a temperature optical signal which is directly proportional to the temperature of the system. The temperature optical signal is provided for temperature compensation of the strain optical signal. The optical sensors include an optical fiber having intrinsic Bragg grating sensors formed in the optical fiber. The optical fiber is attached to a reference point and to the Bourdon tube such that changes in the position of the tube changes the strain on the optical fiber resulting in a wavelength shift of light reflected by the Bragg grating. The magnitude of the wavelength shift is directly proportional to a change in pressure.

摘要： A well assembly for extracting production fluids from at least one production zone of at least one well includes a production pipe for transporting fluid downstream to a surface, a packer for defining the production zone, and a fiber optic sensor package disposed substantially adjacent to a downstream side of the packer. The fiber optic sensor package measures parameters of the production fluid and communicates these parameters to the surface to determine composition of the production fluid entering the production pipe through each production zone. The production pipe has a zone opening for allowing the production fluid to enter the production pipe and a control valve for controlling the amount of production fluid flowing downstream from each production zone. The production pipe control valve is adjusted to optimize fluid production from the particular production zone of the well based on fluid parameters measured by the fiber optic sensor package.

摘要： A fiber optic sensor includes a sensor element responsive to a property or condition of a material, such a resistivity, capacitance, inductance, frequency, etc., for providing an output voltage signal that is dependent upon the property or condition of the material. The sensor further includes an optical-to-electrical conversion element, such as a photo detector or a solar cell, that converts an optical signal (photo detector driving optical signal) carried by an optical fiber into an electrical signal. The electrical signal is applied to the sensor element, and in response, the sensor element provides the output electrical signal. The output electrical signal is applied to a measurement device, such as a piezoelectric element, having at least one dimension that varies with changes in the output electrical signal. An optical strain sensor, such as a Bragg grating or Fabry Perot interferometer, is mounted to the measurement device such that changes in the dimension of the measurement device causes changes in the strain of the optical strain sensor. These changes in strain are detected and related to the property or condition of the material. The fiber optic sensor is particularly useful as a resistivity sensor for measuring the resistivity of a fluid. For example, the resistivity of a fluid mixture of oil and water can be measured for determining the relative water and oil content in the fluid mixture. In this configuration, the sensor element includes a pair of spaced apart conductive elements. The output electrical power from the photo detector is applied to the conductive elements and the fluid is passed between the conductive elements. The output voltage from the conductive elements varies in relation to the resistivity of the fluid sample between the conductive elements.

摘要： A pressure transducer using as a component for changing shape in response to a change in the pressure being measured a composite elongated body, with specially arranged reinforcing fibers. Such a pressure transducer can use various means for sensing the change in shape of the elongated body, including an optical fiber affixed to the elongated body so as to itself change in length in response to a change in pressure, and having a Bragg grating as part of the optical fiber, with the Bragg grating positioned and arranged so as to convey, in response to an optical signal, information about the change in shape of the elongated body. The elongated body is provided with at least one pair of contra-helically wound reinforcing fibers, which may even be bi-axially braided, and are wound either to amplify the effect of pressure acting on the elongated body or to insulate the elongated body from the effects of pressure and other sources of stress. The reinforcing fibers are embedded in a resin, and in some applications more than one pair of contra-helically wound reinforcing fibers are used, so that the composite body consists of more than one layer of reinforcing fibers. The resulting elongated body is a non-isotropic material and can be designed to have a Poisson's ratio significantly greater than ½, the maximum possible Poisson's ratio for an isotropic material, providing an enhanced axial strain accompanying any radial or circumferential strain. The elongated body can also be designed to have a small Poisson's ratio by using an inner layer and outer layer of contra-helical windings where the reinforcing fibers of the two layers intersect at different angles.
