%X In order to generally evaluate the effect of temperature, effective stress and water-saturate to the permeability of tight sandstone, it measured the permeability of tight sandstone at various conditions. It qualitatively analyzed the effect of temperature, effective stress and water-saturate to the permeability of tight sandstone and relationship of them. The experimental result shows that temperature has greater effect on permeability at lower effective stress level but decreases with the increasing of effective stress. Higher of water saturation of sandstone, greater effect of temperature on permeability. The relationship between permeability and effective stress is approximatively exponent but is necessary to correct at high temperature and water-saturate level. Water\ermeability greatly decreases when effective stress increased.
