    摘要： Various embodiments include apparatus and methods of determining the viscosity of a fluid downhole in a well. A parameter of a response signal, obtained from driving a tube containing a fluid with an excitation signal for vibrating the tube, can be collected while maintaining the tube in a vibrating mode. The parameter can be evaluated to measure the viscosity of the fluid. In various embodiments, the fluid viscosity may be measured in-situ downhole in the well.

    摘要： An instrument for determining fluid properties is provided. The instrument (300) includes a tube (304) receiving the fluid, a single magnet (302) attached to the tube, and a single coil (306) wound around the single magnet. The single coil is coupled to a pulse current source (312) and receives a pulse current that creates a magnetic field in the single coil, the created magnetic field interacting with the single magnet to drive the tube to vibrate. The instrument further includes a detector (306) coupled to the tube, wherein the detector is coupled to measurement circuitry (310) and detects properties of the tube as it vibrates, and the measurement circuitry determines the fluid properties based on the detected properties. The instrument also includes a housing (314) enclosing the tube, the single magnet, and the single coil wound around the single magnet.

    摘要： A sensor for measuring a density of a fluid is provided. The sensor (200) includes a flow tube (104) for receiving the fluid and a vibration driver (102) coupled to the flow tube, the vibration driver configured to drive the flow tube to vibrate. The sensor also includes a vibration detector (106) coupled to the flow tube, the vibration detector detecting characteristics related to the vibrating flow tube, and a distributed temperature sensor (202) coupled to the flow tube, the distributed temperature sensor measuring a temperature of the flow tube as the flow tube vibrates. The sensor further includes measurement circuitry (110) coupled to the vibration detector and the distributed temperature sensor, the measurement circuitry determining a density of the fluid from the detected characteristics related to the vibrating flow tube and the measured temperature of the flow tube.
