%X The relationship between permeability of the Daqing sandstone and hydrostatic pressure is studied by means of experiment. Based on an ideal model, a formula a relating permeability under hydrostatic pressure with the permeability on surface and the pressure isobtained. After using the least square method,we simulate the experimental data and determine tbe parameter in the formula. The results show that the model established is reasonable.
