| Zusammenfassung: | The utility model relates to an acoustic system of an imaging log, in particular to an acoustic system of an octa-sector cement bond imaging log. The acoustic system comprises a group of conventionaltransmitting transducers and two groups of conventional receiving transducers corresponding to the conventional transmitting transducers, the upper parts of the conventional transmitting transducers are connected with a transmitting transducer assembly formed by another group of octa-sector ultrasonic transmitting transducers in an insulation way, and the two groups of conventional receiving transducers are added with a group of octa-sector ultrasonic receiving transducers corresponding to the octa-sector ultrasonic transmitting transducers; and the added ultrasonic transmitting transducers and ultrasonic receiving transducers are respectively formed into an octa-sector symmetrical structure with eight ultrasonic transducers circumferentially evenly arranged at an included angle of 45 degrees. Each transmitting tr |
