In the use of SKC3700 sonic logging tool, we found there exist some defects in the cartridges of logic regenerator card, logic decoder card and main amplifier card, etc., e.g., the transducers easily send wrong signals and the sign pulses are heavily interfered when the tool is combined with the induction logging tool. Causes producing the above defects are analysed, based on which several improvements are proposed. After improvements, the tool′s reliability has been enhanced.
