  • Publication number: 20200064505
    Abstract: A frequency-shifting system and method for cement-bond-logging tools is disclosed. Shifting the frequency of a received acoustic signal to a lower signal for transmission on a wireline is accomplished by digitizing the received signal at a first sampling rate, storing the digitized data in memory, and converting the digitized data to an analog signal at a second sampling rate. The digitizing sampling rate is higher than the conversion sampling rate. This allows an acoustic operating frequency that is greater than the wireline transmission frequency, and therefore allow signal-to-noise optimization not available in conventional systems. Acoustic transducers can be operated at higher frequencies than what is acceptable for wireline transmission. This allows for the use of transducers not conventionally used in the art (such as piezoelectric stacks).

  • Patent number: 5670931
    Abstract: The present invention impresses the data on the power signal by utilizing a saturable core reactor. The saturable core reactor uses two cores. Each core has both load windings and control windings. The control windings are selectively energized to alter an electrical characteristic of the current passing through the load windings. The saturable core reactor is designed with cores made of a highly magnetically permeable material so that the cores are easily saturated. The cyclical saturation of the cores achieved by the load current, and the selective saturation of the cores achieved by selectively applying a control current, results in "deformations" being selectively formed at the zero crossings of the load current waveform. These "deformations" can be selectively formed on the power signal to represent a binary data stream.
