On the development of the emitter assembly of an acoustic downhole device

Abstract

The article considers narrow-band and broadband variants of the acoustic logging method, shows the advantages and disadvantages of existing radiators, describes the requirements for acoustic radiators of borehole devices for a wide frequency range from 0.5 to 40 kHz, shows the experimental and theoretical justification of the designs of radiator assemblies and the basic requirements for calculations. The result of the work is an upgraded design of the radiator assembly, which ensures the operation of broadband acoustic logging devices, described in detail in this article.
