Dielectric logging is commonly used for detailed fluid evaluation in complex reservoirs, characterized by its minimal influence from formation water salinity, as the dielectric constant of the reservoir primarily depends on the water content. This paper presents an engineering design approach for a dielectric measurement probe embedded with orthogonally dual-polarized antennas. For the engineered prototype structure of a dielectric measurement probe embedded with orthogonally dual-polarized antennas, numerical simulations incorporating the engineering parameters of a dual-polarized array dielectric logging tool were conducted. A simulation model of the dielectric measurement probe embedded with cavity-backed slot antennas was established. Through 3D-FVM simulations incorporating mesh optimization, equivalent electromagnetic parameters, and advanced boundary handling techniques, this study systematically investigated how probe components and downhole conditions affect measurement responses. The derived data processing method has demonstrated practical value in reservoir evaluation, particularly for waterflood monitoring in mature fields.
