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.
摘要翻译： 本发明是一种声发射器（301,401），其在由电动驱动器致动时将振动应力施加到诸如油井管的信号传播介质上。 在一个实施例中，声学发射器（301,401）利用包括压电元件（304）的机械驱动器来产生振动应力。 声发射器（301,401）仅在一个点上机械地连接到信号传播介质。 这种单点连接消除了声学发射器（301,401）上由信号传播介质携带的压缩力和拉伸力的负载。 支撑机械驱动器的质量块（406）可以用于扩展声学发射器（301,401）可操作的频率范围。 另外，声发射器（301,401）的谐振响应可通过使用粘滞阻尼器（409）而最小化。 粘性阻尼器（409）被配置为当声学变送器正在操作时与机械驱动器“联接”并且在其他时间与机械驱动器“脱开”。

摘要： The location of a downhole source (30) of a transmitted acoustic signal is determined using at least one downhole signal receiver (40,42,44,46,48). Either or both the triangulation method and the holographic method are used to determine the signal location.

摘要： A subterranean reservoir (118A,118B) is monitored using an array (140) of sensors (210) disposed on an umbilical cable (211) attached to tubing (126) extending into the well (100). The sensor array includes a series of evenly spaced sensors, eg. three-component accelerometers, individually mounted on biasing members (212), such as bowspring centralizer fins, which clamp the sensors to an outer casing (112) to establish a mechanical coupling between the sensors and the surrounding formation.
