There are many restrictions in using this tool. Excessively thin beds, boreholes filled with conductive muds, high resistivity formations, and large invasion diameters are situations where induction log response is poor. To minimize these limitations, it is necessary to know tool response in given conditions. This can be partially acomplished by scale modeling and/or digital modeling. The present thesis describes the construction of an experimental analog model system designed to simulate the two coaxial coils induction tool in three different geological situations. The geological medium is simulated by brine solution of diferent conductivities. The linear scale factor is twenty and the frequency range of the measuring system is 50 kHz to 100 kHz. This system can be utilized in future research work with different coil arrangements from the ones currently being used by the service companies and also to study other problems encountered in induction logging.porAcesso AbertoProspecção - Métodos geofísicosPerfilagem geofísica de poçosConstrução de um modelo experimental simulando condições de perfilagem de induçãoConstruction of an experimental set-up simulating induction logging conditionsDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICA::GEOFISICA APLICADA
