Abstract: There is more attention on pressure change of water injection to the permeability of layer at home and abroad, but a little research on the temperature influence. Experiment results shows: the fluid permeability rate through porous media decreased with the decreasing of the temperature, the depressed range is related with the temperature and media's initial permeability rate and the penneability decrease is part of irreversible. It gives part of support to whether water injection development and construction will bring cold damage to low permeable oil field and high concentration should be gave in oil field development practice in the future.
