摘要： A system (100), method and device may be used to monitor conditions in a borehole. Well tubing and casing (120) act as a conductive pair for delivering power to one or more downhole active sensors (124, 310). At the surface, power and signal are isolated so that the same conductive pair may act to transmit the sensor signals to the surface. In an embodiment, the sensor signals are RF signals and the surface electronics (112, 114, 118) demodulate the RF signals from the sensor power.

摘要： A system, method and device (100) may be used to monitor conditions in a borehole. Energy is transmitted to a pulse generator located proximate a position to be interrogated with a sensor. The pulse generator stores the energy, then releases it in a pulse of electromagnetic energy, providing the energy to resonant circuits that incorporate the sensors. The resonant circuits modulate (120) the electromagnetic energy and transmit the modulated energy so that it may be received and processed in order to obtain the desire measurements.

摘要： Exemplary systems and method are directed to a sensing device, and to a pressure sensing system and method. An exemplary method includes supplying electromagnetic energy to a transducer which is configured to reflect the electromagnetic energy at a ring frequency determined by an inductance of the transducer, wherein the inductance changes in response to compression of the inductive element. The ring frequency of electromagnetic energy reflected by the transducer is correlated to a pressure value.

摘要： A sensor is configured to sense pressure in an isolated or subterranean environment. The sensor is configured to act as a capacitor with a capacitance that varies as a function of pressure. The sensor has a robust design with minimal moving parts, and in which any parts that do move do not communicate electrically through direct electrical conduction (e.g., through conductive leads). Instead, moving parts that participate in the performance of sensor as a capacitor receive and dispense electrical charge only through a dielectric fluid (e.g., a gas or liquid within the sensor). This may reduce hysterysis, lag, and/or friction with respect to pressure-dependent capacitor designs in which wiring is connected directly to moving parts.
摘要翻译：传感器被配置为感测隔离或地下环境中的压力。传感器被配置为充当具有随压力变化的电容的电容器。传感器具有坚固的设计，具有最小的移动部件，并且其中任何移动的部件不通过直接电传导（例如，通过导电引线）进行电气通信。相反，参与作为电容器的传感器性能的移动部件仅通过介电流体（例如传感器内的气体或液体）接收和分配电荷。这可以减少相关于直接连接到移动部件的布线的压力相关电容器设计的滞后，滞后和/或摩擦。

摘要： Exemplary systems and methods are directed to transmission of electromagnetic (EM) pulses in a downhole environment, which is located below a surface of a landform. A sequence of EM energy pulses is generated from a signal generator located at the surface of the landform. The energy pulses are reflected at a ring frequency by one or more downhole transducers. The reflected energy pulse is received at a receiver, which is located at the surface, during a predetermined time interval. The receiver detects the received energy pulses through a time domain or frequency domain technique. The detected ring frequency is correlated to a parameter or condition of the downhole environment.
