The invention provides a device and a method for correcting an acoustic
logging tool through indoor
frequency dispersion analysis. The method comprises the following steps: 1, mounting a centering device according to the design; 2, pushing the instrument sequentially from bottom to top joint by joint into a testing tube from one end provided with a jack; 3, mounting an upper plug and a lower plug;4, mounting a valve, a
water pipe and a pressurizing pump; 5, injecting water and pressurizing, and regulating the pressure to 30kg; 6, connecting the instrument, switching on the instrument, and acquiring the data by using a dedicated acquisition
system; 7, analyzing data,
processing a correction value, and storing into a dynamic
library; and 8, transferring
logging data to an explanation centerwhen the instrument is logged and used, and directly correcting the data during
processing. The device and the method for correcting an acoustic
logging tool through indoor
frequency dispersion analysis disclosed by the invention have the advantages that a testing instrument is corrected, the equipment performance is stable, a structure is simple, the device is convenient to transport, the manufacturing cost is low, maintenance is convenient, correction
software is implanted into the dynamic
library of the instrument, and the method can be applied to all acoustic amplitude measurement.
