A rapid detection method for emission system performance of dipole sonic logging tool

This paper proposes a rapid detection method for the performance of the emission system of dipole sonic logging tool. Through experimental measurement, the sound field excited by the emission system of dipole sonic logging tool is measured by acquisition device specially designed, and some characteristic parameters such as intensity, dominant frequency and spatial distribution symmetry are extracted. If these characteristic parameters when the dipole sonic logging tool is in good condition are accurately mastered and used as references, a rapid evaluation of the emission performance of the tool can be achieved by comparing references with experimental measurements. Compared with the existing dipole sonic logging tool detection methods, this method has the advantages of high efficiency and convenience, and is easy to be applied in the logging site.
