ROCK PROPERTIES BY TIME-DOMAIN SPECTROSCOPY

摘要

A method and system for measuring rock electrical properties using time-domain spectroscopy. The rock to be measured is place in direct contact with the substantially flat face of a sample cell. A voltage pulse is launched into a coaxial line connected to the sample cell. The pulse propagates through the sample cell and reflects from the rock. The incident voltage pulse and reflected voltage signal are analyzed to determine the rock's conductivity as well as the rock's dielectric constant over a broad frequency range.
