Product Description
HAP tool a new tool which could be with a small CNC system for combination logging.
It uses a large-size piezoelectric ceramic transducer (transducer's diameter increases 20%),
increasing the acoustic emission power, reducing the acoustic attenuation in the formation;
It use metal bellows and Acoustic-Transmission cover, improve acoustical efficiency and reduce the direct coupled wave , avoid the penetration of H2S; Logic control part of circuit use CPLD, to simplify the design, to meet requirement of the high integration and high reliability.
It could be used directly in 3700 systems ,521 systems , domestic system such as xinxiang 3000 system .
The waveform is stability when logging , interference is small ,logging-curve expectation is high.
