Improvement of Electrode System of SDZ-3060C Dual Laterolog Tool

Dual lateral logging can simultaneously measure the formation resistivity of original state and invaded zone. SDZ-3060C bilateral electrode system is seriously worn during the logging process, which influenced seriously the quality of logging. Through analysis the structure of the electrode system, the solution method has been found out. Great improvement has been made in wiring design of the electrode system, the wear of electrode system and the insulation of the electrode system. These measures can ensure the quality of well logging instrument and improve the logging success rate.
