ACOUSTIC BOREHOLE RADIATOR Russian patent published in 2021 - IPC E21B43/25 E21B28/00 

FIELD: geophysics; applied acoustics.

SUBSTANCE: acoustic borehole radiator belongs to the field of geophysics and applied acoustics and can be used for cross-well acoustic transmission, obtaining information about the internal structure of a rock mass in the inter-well space when inspecting buildings and structures. An acoustic borehole radiator has a part (1) of an acoustic borehole radiator, which is run down into the well, an N-position switch (2), a power amplifier (3), a null element (4), a frequency divider (5) with a division ratio of N/2, the first key (6), the second key (7), a controlled inverter (8), a 2^n-1 - bit cyclic shift register (9), a two-input adder (10), a trigger (11), multipliers (12).

EFFECT: technical result consists in increasing the accuracy of assessing the internal structure of the rock mass in the inter-well space when examining buildings and structures in the course of inter-well acoustic transmission.
