The cOmpOsite electrOde array in electrOkinetic lOgging detectOrs was studied, with fOcuses On its structure, wOrk-ing principle, electrOnic system principle and testing. A numerical mOdelling study with the electrOde array was carried Out u-sing finite element methOd, then the results in the electric field respOnse were analyzed tO sOlve fOr the numerical sOlutiOn Of the electrOde array cOefficient. Next, the electrOnic circuit principle Of the cOmpOsite electrOde array was alsO analyzed, and pOwer-On test and high temperature experiment with the exciting circuit and data acquisitiOn circuit system were alsO cOnduc-ted . The results shOw that this detectOr successfully merges acOustic lOgging and electric lOgging detectOrs with different struc-ture and material tOgether, and can align the acOustic and electrical signals in the depth Of the recOrd pOint; the electrOnic circuit system functiOns well in high temperature and then can be experiment in dOwnhOle. The results alsO suggest the tech-nique has great feasibility fOr dOwnwhOle field tests and analyzing electrOkinetic lOgging tOOl.
