AN ULTRA-WIDEBAND MEASUREMENT METHOD OF ROCK PERMITTIVITY

摘要

Electrical properties of sediment rocks is essential to the data interpretation of electrical and electromagnetic logging. An optimized ultra-wideband parallel-plate capacitor device is proposed to achieve the electrical parameters measurement. The validity and accuracy of the proposed measurement system is verified by experimental results. The results show that a better accuracy and stability of the measurement system can be achieved with the optimized parallel-plate capacitor model while the upper limit of measurement frequency can reach 1.5 GHz.
