High Resolution Acoustic Televiewer
طرق سهلة سريعة لكسب المال The HRAT (High Resolution Acoustic Televiewer) provides a continuous high-resolution oriented ultrasound image of the borehole wall.
ديلى فوركس The probe uses a fixed acoustic transducer and a rotating acoustic mirror to scan the borehole walls with a focussed ultrasound beam. The amplitude and travel time of the reflect
الخيارات الثنائية التداول التطبيق فون Features such as fractures reduce the reflected amplitude and appear as dark sinusoidal traces on the log. The travel-time log is equivalent to a high-precision 360-arm caliper and shows diameter changes within open fractures and ‘break-outs’. Directional information is also recorded and used to orient the images in real time.
