Paper Abstract

In the petroleum geology field, quartz sandstone becomes one of the main sandstone reservoirs because of its preferable porosity. The particle size of quartz sandstone is related with the porosity, which has a significant relationship with oil and gas storage. It has a great significance to study the properties of quartz sandstone. In this paper, the terahertz time-domain spectroscopy (THz-TDS) system is used to detect quartz sandstones with different particle and impurities. Results show that the smaller particle is, the longer delay time is, and the smaller absorption coefficient is. In addition, chalybeate quartz sandstone reflect obviously different response in terahertz range. This suggests that terahertz technique can clearly characterize the particle of quartz sandstone indirectly reflecting the porosity of quartz sandstone and has a guiding significance for oil and gas exploration.
