Ultrasonic Noise

الخيارات الثنائية تاجر The noise module detects points of entry of high-pressure gas into an open borehole by listening for an ultrasonic signature.

Principle of Measurement:

هذا الرابط Sound energy caused by gas entering the borehole is focused by a conical acoustic mirror within the probe onto a microphone. The microphone is tuned to measure the acoustic energy in a frequency band centred at 40kHz, characteristic of entry of high- pressure gas through a narrow orifice.

  • Dual detectors in a differential configuration to reduce background noise
  • High-sensitivity microphones with acoustic focusing
  • Fully digital telemetry combines with density, neutron and other logging probes
  • Easy field access for replacement of microphones
