摘要： An array of fiber optic acoustic sensors (115, 120, 125, 130) is formed within an optical fiber (110). The array of acoustic sensors (115, 120, 125, 130) may be deployed to a well bore (55), such as acoustic signals resulting from sand invading the well bore (55). A plurality of acoustic sensors may be formed by forming a plurality of periodic refractive index perturbations at selected intervals within the acoustic sensing section (115) of the optical fiber (110). The optical fiber (110) may be deployed within the well head within a suitable protective arrangement such as deployed through a tube or armor (35) using a suitable arrangement such the optical fiber (15) is protected, yet retains sensitivity to acoustic signals. The fiber optic acoustic sensor of the present invention may be unobtrusively mounted on the exterior of a well casing such that the sensor is not in the fluid stream.
摘要翻译：在光纤（110）内形成有一组光纤声学传感器（115,120,125,130）。声学传感器阵列（115,120,125,130）可以部署到井眼（55），例如由入侵井井（55）的沙子产生的声信号。可以通过在光纤（110）的声学感测部分（115）内以选定的间隔形成多个周期性折射率扰动来形成多个声学传感器。光纤（110）可以在合适的保护装置内展开，例如通过管或装甲（35）展开，使得光纤（15）受到保护，但保持对声信号的灵敏度。本发明的光纤声学传感器可以不显眼地安装在井套管的外部，使得传感器不在流体流中。

摘要： A fiber optic sensor assembly capable of deployment down an instrumentation tube (6) located in a well bore (12), including a flexible protective tube (28) having a lumen encasing an optical fiber having a core portion and a cladding portion disposed within the flexible tube. The flexible protective tube protects the optical fiber from the oil, water or hydrogen gas within the well bore. A method of deploying the optical fiber down the well bore, is also provided. An optical fiber having a core and a cladding surrounded by the flexible protective tubing is deployed into the lumen of a tube disposed within the well bore by pumping a high pressure fluid into the lumen of the tube, thereby causing the deployment of the optical fiber down the well bore. The protective tubing is impermeable of hydrogen and other corrosive materials.

摘要： An array of fiber optic hydrophones (30) is formed by winding of optical fiber around a continuous, yet flexible cylindrical core (31). The cylindrical core contains an elastomer filled with a specified percentage of voided plastic microspheres. The elastomer provides the necessary radial support of the optical fiber and with the included voided microspheres, provides sufficient radial compliance under acoustic pressure. The cylindrical core can be made in very long sections allowing a plurality of hydrophones to be wound onto it using a single optical fiber, with individual hydrophone elements separated by internal reflectors such as Fiber Bragg Gratings (32). The center of the core may include a strength member and a central hollow tube for the passing of additional optical fibers. The aforementioned hydrophone array is then packaged within a protective outer coating or coatings as required for the specified application.

摘要： A gyroscope assembly (10) includes a ring-shaped fiber optic coil (14) and a coil conforming enclosure (12, 16) of high magnetic permeability ferromagnetic material. The enclosure is ring-shaped to conform with the shape of the coil, and includes a portion (22) extending within the internal hole of the coil ring. Therefore, the coil is intimately and fully encased within high magnetic permeability material. In particular, the enclosure comprises a coil supporting spool (12) and a cover (16) secured to the spool. The spool includes a base (18) which is provided with a central hole (20) and a tubular wall (22) extending perpendicularly from the base. Coil (14) is bonded to base (18). Both the spool and the cover are formed of high magnetic permeability material, and the cover is placed about the fiber optic coil and attached to the spool. The coefficient of thermal expansion material used for the spool is matched to that of the coil pack to minimize stress imposed upon the fiber. An outer shield (28), roughly cylindrical in shape, may be further attached to the outside of the inner, toroidal shield, and the two shields are separated by a layer of low magnetic permeability material, such as of low magnetic permeability stainless steel or aluminum. 00000
