摘要： A clamp for clamping optical fiber to a tube. The clamp has a body portion coupled at one end to a first arm and at an opposing end to a second arm, and a resilient portion to permit the clamp to elastically deform from a closed state in which the clamp is fastened around the tube to an open state in which the clamp is radially moveable off the tube. At least one of the body portion, the first arm and the second arm has a clamping surface to clamp a portion of the optical fiber against the tube when the clamp is fastened around the tube, and a clamping mechanism operable to extend at least part of the clamping surface towards the tube when the clamp is secured to the tube to increase a clamping force applied by the clamping surface.

摘要： A method for determining relative location of an acoustic event along a channel such as a wellbore includes obtaining two acoustic signals at are obtained at two different and known depths in the wellbore, dividing the acoustic signals into windows, and determining the relative loudnesses of pairs of the windows. The power of the acoustic signals may be used as a proxy for the loudness of the acoustic event, and this determination can be made in the time or frequency domains. The relative depth of the acoustic event can then be determined relative to the two known depths from the relative loudnesses. The acoustic event may be, for example, casing vent flow, gas migration, a leak along a pipeline, or sounds observed in an observation well from a nearby well in which fracking is being performed.

摘要： A sound baffle device for use with an acoustic sensor deployed in a housing by a deployment line is disclosed. The sound baffle device comprises a radially extending baffle plate and an affixing mechanism for affixing the baffle plate to the deployment line. The baffle plate is configured to reduce acoustic transmission between a first zone of the housing on one side of the baffle plate and a second zone of the housing on an opposite side of the baffle plate. A system for detecting acoustic signals in a zone of interest in a housing is also disclosed. The system comprises an acoustic sensor positioned in the zone of interest and one or more than one sound baffle positioned between the zone of interest and a first zone of the housing. The sound baffle is configured to reduce acoustic transmission from the first zone to the zone of interest. The sound baffle provides some level of acoustic isolation between two zones on either side of the baffle plate thereby aiding detection and identification of acoustic signals in the zone of interest by reducing transmission of acoustic signals from the first zone to the zone of interest.

摘要： An apparatus for detecting acoustic signals in housing is disclosed. The housing may be housing of a wellbore, riser, tubular or pipeline or the like for transporting fluids or housing of a vessel for storing fluids. The apparatus comprises a longitudinally extending tube having an internal surface and an external surface, a longitudinally extending fibre optic cable disposed within the tube, and one or more than one longitudinally extending outer fins radially extending outwards from and coupled with the external surface of the tube.

摘要： Methods, systems, and techniques for wind detection. A first acoustic signal generated by an acoustic sensor positioned to be actuated in response to wind is measured. An average value of the first acoustic signal over a sampling duration is determined. The average value may be a median, and the sampling duration may be at least 15 minutes. If the average value of the first acoustic signal satisfies a wind detection threshold, the first acoustic signal is determined to be generated by the wind.

摘要： An apparatus includes an enclosure having one or more apertures for receiving therethrough optical fiber, and one or more actuators sealed within the enclosure for generating one or more interference signals for interfering with optical fiber within the enclosure such that an optical path length of the optical fiber is altered. A method for verifying an event detection system includes interrogating optical fiber positioned alongside a conduit by sending one or more light pulses along the optical fiber and receiving reflections of the one or more light pulses. The method further includes using an event verification device housed within an enclosure through which passes the optical fiber to generate one or more interference signals for interfering with the optical fiber such that an optical path length of the optical fiber is altered.

摘要： A method of wrapping optical fiber around a fluid conduit. The optical fiber is wrapped at least partially around the conduit. The optical fiber is secured relative to the conduit at one or more securing locations, thereby defining a sequence of multiple optical fiber portions. Each optical fiber portion comprises a portion of the optical fiber. Each securing location delimits a given optical fiber portion from the subsequent optical fiber portion in the sequence of optical fiber portions. A direction of wrapping of each consecutive optical fiber portion in the sequence of optical fiber portions may be alternated between a clockwise direction and a counter-clockwise direction.

摘要： A system and method for detecting dynamic strain of a housing. The system includes an optical fiber linearly affixed along a surface of a length of the housing and an interrogator comprising a laser source and a photodetector. The optical fiber comprises at least one pair of fiber Bragg gratings (FBGs) tuned to reflect substantially identical wavelengths with a segment of the optical fiber extending between the FBGs. The segment of the optical fiber is linearly affixed along the surface of the housing. The interrogator is configured to perform interferometry by shining laser light along the optical fiber and detecting light reflected by the FBGs. The interrogator outputs dynamic strain measurements based on interferometry performed on the reflected light.

摘要： There is described a method of determining a position of a pipeline inspection gauge (PIG) in a fluid conduit. While the PIG is moving through the fluid conduit, one or more sensors positioned along the fluid conduit are used to detect one or more signals. Parameter data is extracted from the detected one or more signals. The parameter data includes one or more parameters of the detected one or more signals as a function of time and position along the fluid conduit. PIG movement data indicative of a position of the PIG in the fluid conduit as a function of time is generated using the parameter data.
