摘要： A downhole optical sensor system includes at least one optical sensor positioned in a borehole and coupled to an interface via a fiber optic cable. Each of the optical sensors includes a waveguide for conducting light, and a reagent region positioned between the waveguide and a fluid in the borehole to absorb a portion of the light from the waveguide, the portion being dependent upon a concentration of a chemical species in the fluid. A method for operating a well includes deploying one or more downhole optical sensors in a fluid flow path in the well, probing the one or more downhole optical sensors from a surface interface to detect concentrations of one or more chemical species, and deriving a rate of scale buildup or corrosion based at least in part on the detected concentrations.

摘要： Distributed density, temperature and/or strain sensing is utilized for downhole monitoring. A method and system for monitoring a rapidly changing parameter in a well includes: detecting gain-based stimulated Brillouin backscattering due to light transmitted through at least one optical waveguide installed in the well, the Brillouin backscattering being dependent upon temperature and strain experienced by the waveguide in the well. The method can include measuring at least one of temperature and strain in the well, with the measurement being performed separately from the step of detecting Brillouin backscattering.

摘要： A method and system for monitoring the operation of downhole equipment, such as electrical submersible pumps, is disclosed. The method and system rely on the use of coiled fiber optic sensors, such as hydrophones, accelerometers, and/or flow meters. These sensors are either coupled to or placed in proximity to the equipment being monitored. As the sensor is perturbed by acoustic pressure disturbances emitted from the equipment, the length of the sensing coil changes, enabling the creation of a pressure versus time signal. This signal is converted into a frequency spectrum indicative of the acoustics emissions of the equipment, which can then be manually or automatedly monitored to see if the equipment is functioning normally or abnormally, and which allows the operator to take necessary corrective actions.

摘要： A structure for incorporating fiber optic acoustic sensor in a seismic array includes means for supporting the sensor in a spiral around a central strength member in a manner to isolate shear waves from the sensor. In another aspect, an axially oriented sensor in a seismic array comprises a pressure sensitive optical fiber wound in a spiral around the axis, the fiber having a plurality of optical Bragg gratings and a plurality of channels. The preferred structure may include four tubes spiraling around the strength member. One of the tubes encloses an optical fiber sensor which is maintained in an extended orientation by fluid flow through the tube. Another of the tubes serves as a return path for fluid through the sensor tube. The other tubes enclose high speed and low speed data conductors, respectively. The sensor fiber may also be wound in a spiral around a compliant core in a manner to satisfy Poisson's Ratio such that strain on the compliant core does not alter the tension of the sensor fiber.
