The electrical resistivity and dielectric constant of the sandstone, which came from the DK-8 well in the Qilian hydrate drilling areas, were measured during the natural gas hydrate formation process. After the hydrate generated, the electrical resistivity of sandstone samples increased dramatically. During the temperature shock, the second formation of hydrate or ice could be detected by electrical resistivity measuring. During the hydrate formation process, the dielectric constant change law of the system is complex. In the frequency range of 1 kHz ~ 100 kHz, the hydrate-bearing rock samples show disperse characteristics. The dispersion grows weaker when the frequency is over 100 kHz. The dielectric constant of electrical exploration could be applied to qualitatively analyze the hydrate bearing reservoir, but it is difficult to quantitatively analyze the saturation of hydrate in the reservoir.
