    摘要： The invention is an acoustic transmitter (301, 401) that imparts vibratory stresses onto a signal propagation medium such as oil well tubing when actuated by an electric driver. In one embodiment, the acoustic transmitter (301, 401) utilizes a mechanical driver that includes piezoelectric elements (304) to generate the vibratory stresses. The acoustic transmitter (301, 401) is mechanically attached at only one point to the signal propagation medium. This single point attachment eliminates loading on the acoustic transmitter (301, 401) from compressive and tensile forces carried by the signal propagation medium. A mass (406) backing the mechanical driver may be used to extend the frequency range over which the acoustic transmitter (301, 401) is operable. In addition, the resonance response of the acoustic transmitter (301, 401) may be minimized by the use of a viscous dampener (409).; The viscous dampener (409) is configured to "couple" with the mechanical driver when the acoustic transmitter is operating and to "uncouple" with the mechanical driver at other times.

    摘要： In situ testing of formation fluid conditions and optionally selective collection of formation fluid samples are effected using a probe (29) that is sealingly placed against the wellbore formation (22) to withdraw formation fluids, a surface controlled pump (13) to control the flow of a fluid from the formation into a flowline (14), and an acoustic density cell (15) to provide the speed of sound in the fluid, acoustic impedance of the fluid and acoustic absorption coefficient of the fluid in the flowline. Sample chambers (18) may be provided to receive and store formation fluid admitted from flowline (14) via valve (17). The system can also be used for other related tests downhole.

    摘要： A fluid property monitor includes a transducer assembly (T, 26') to impart multiple frequency energy to a conduit in one or more modes and to receive (T, RECEIVER) resonant frequency energy from the conduit. The resonant frequency energy is responsive to the imparted energy, the conduit and a fluid in the conduit. The monitor can also include: a frequency signal generator connected to cause multiple frequency energy to be transferred to a conduit having a fluid to be monitored; and a spectral analysis signal processor connected to receive and process electrical signals generated in response to vibrations propagated through the conduit and the fluid in the conduit in response to transferred multiple frequency energy. Particular implementations can be adapted as a densitometer, a coherent flow detector, and other particular fluid parameter detectors.
