45mm Full-waveform Triple Sonic

شاشة الاسهم السعودية This highly compact slimhole tool is designed specifically for geotechnical and mining applications. The probe acquires transit-time and full-waveform data simultaneously from a single transmitter and three receivers.

Principle of Measurement:

http://craigpauldesign.co.uk/?izi=%D8%A7%D8%B3%D8%B9%D8%A7%D8%B1-%D8%B4%D8%B1%D8%A7%D8%A1-%D9%88%D8%A8%D9%8A%D8%B9-%D8%A7%D9%84%D8%B0%D9%87%D8%A8-%D8%A8%D8%A7%D9%84%D8%B3%D8%B9%D9%88%D8%AF%D9%8A%D8%A9-%D8%A7%D9%84%D9%8A%D9%88%D9%85&cc5=ae اسعار شراء وبيع الذهب بالسعودية اليوم The piezoelectric transmitter is stimulated by a high-voltage pulse and radiates a high-frequency acoustic wave through the borehole fluid and formation to each receiver. An accurate quartz clock measures the first arrival transit time.

Compensated sonic mode:

أخبار Three receivers are used. The probe measures the time of the first compressional arrival at each receiver. The difference in arrival times between each pair of receivers allows determination of formation velocity independent of the borehole fluid path.

Full-wave sonic mode:

انقر هنا لقراءة The probe records the full sonic wave-train at all receivers simultaneously. This can be displayed either as a variable-density log (VDL) or as a waveform (wiggle trace). The waveform data may be exported to packages such as WellCAD™ for calculation of compressional, shear and Stoneley velocities.
