Abstract Rock salt cavern is widely used for nuclear waste disposal，petroleum and natural gas storage and CO2 sequestration. The permeability of rock salt is too low to be obtained easily by experiments. The permeability of three different rock salt samples are obtained through the steady-state method. The permeability calculated by pseudo-pressure method and considering Klinkenberg effect are compared. The results show that：(1) The permeability and porosity of rock salt are extremely low，and the porosity is between 0.3% and 3%. The permeability of pure rock salt is about 10－20 m2，greater than that of impurity rock salt，which is between 10－20 and 10－21 m2. (2) During the permeability experiment，when the inlet pressure is 1–5 MPa，Klinkenberg effect is obvious. When the inlet pressure is higher than 5 MPa，the rock salt is damaged and the permeability increases. (3) By comparing the results，the method of considering Klinkenberg effect is more ideal than pseudo-pressure method in rock salt permeability calculation.

Key words： rock mechanics rock salt permeability damage pseudo-pressure Klinkenberg effect
