摘要： The present disclosure relates to vibration frequency sensors comprising a vibratable flow tube having an interior for receiving a fluid, a vibration detector coupled to the flow tube for detecting a frequency of the fluid received by the flow tube during vibration thereof; and measurement circuitry coupled to the vibration detector for determining a frequency shift over time of the detected frequency. At least a portion of a surface of the interior of the flow tube is functionalized with a reactant sensitive to the analyte, and the frequency shift corresponds to the presence of the analyte, the analyte having reacted with the reactant.

摘要： Systems and methods for signaling the detection of a fluid change in a wellbore can be used during wellbore operations, such as cementing a casing in the wellbore. The systems and methods involve using burst discs to provide a pressure pulse that can be detected uphole and there by provide a signal related to when a fluid change has reached a predetermined position in the wellbore. The burst discs can be activated to prevent fluid flow in a portion of the wellbore by a sensor that detects a property that is different between two fluids. Once activated, the pressure of the fluid on the burst discs subsequently ruptures the burst disc and creates the pressure pulse.

摘要： A downhole well fluid sensing device is disclosed for determining thermal conductivity of a formation fluid produced by a sampled subterranean well, the sensor package having an annulus shaped, elongate body defining a cylindrical fluid sampling space, the elongate body and the sampling space having a common longitudinal center axis. The elongate body has a fluid entrance port that provides well fluid ingress into the fluid sampling space and a fluid exit port that provides well fluid egress out of the fluid sampling space. A heat source is coupled to the elongate body and located along a portion of the fluid path, and the heat source inputs heat into sampled well fluid. Finally, temperature sensing devices located between the fluid entrance port and fluid exit port measure heat conducted to the sampled well fluid, wherein each of the temperature sensing devices is radially spaced from the heat source.

摘要： The resonant frequency of an example transducer can be adjusted by changing the effective mass of a backing mass using a tuning module. The tuning module includes a electrical source, a switch, and an electromagnetic coil connected in series as an electrical circuit. The electromagnetic coil is mechanically attached to the backing mass, and is disposed within a reservoir of a magneto-rheological fluid enclosed within a casing. When the switch is closed, the electrical source applies a voltage and current to the electromagnetic coil, and induces a localized magnetic field within the magneto-rheological fluid. In response to this localized magnetic field, the magneto-rheological fluid increases in viscosity, assumes properties comparable to a viscoelastic solid, and become affixed to the electromagnetic coil. As the electromagnetic coil is mechanically attached to the backing mass, the solidified magneto-rheological fluid increases the effective mass of the backing mass. As a result, the resonant frequency of the transducer is altered.

摘要： An acoustic receiver is provided. The acoustic receiver includes an optical vibrometer having an optical emitter and an optical receiver. The optical receiver is operable to emit an optical beam to a single point of reference on a conduit, and the optical receiver is operable to receive one or more reflections of the optical beam off of the single point of reference on the conduit, thereby detecting waves propagating through the conduit created by an acoustic transmitter. A processor is coupled with the optical emitter and the optical receiver. The processor is operable to: determine components of the waves created by the acoustic transmitter based on the one or more reflections of the optical beam; and determine a signal transmitted from the acoustic transmitter based on the components of the waves.
