The invention mainly relates to the technical field of
sound wave velocity measuring, in particular to a while-drilling direction
sound wave imaging
logging device which adopts two sets of transmitting transducers to conduct stimulation of multi-pole model
waves. One set of the transmitting
transducer is a high-frequency mono-pole and biased-pole transmitting
transducer, and the other set is a low-frequency
dipole and quadripole transmitting
transducer. A high-frequency transmitting state and a low-frequency transmitting state are separated through a double-row transmitting scheme, and both the two sets of transmitting transducers can work at transducer
resonance points through matched circuits, so that the transmitting energy is greatly improved. The working mode of the while-drilling direction
sound wave imaging
logging device comprises a mono-pole transmitting mode, a
dipole transmitting mode, a quadripole transmitting mode and a biased-pole transmitting mode; the composite sound insulation mode of an inner engraved groove, inner variable diameters and a
tungsten bar is adopted on the aspect of a sound insulator;
signal receiving is achieved through the high-sensitivity transmitting transducers, and receiving of signals can be effectively achieved.
