In the present work a new method for studying porous media by nuclear magnetic resonance of liquid 3He has been proposed. This method has been demonstrated in an example of a clay mineral sample. For the first time the integral porosity of clay sample has been measured. For investigated samples the value of integral porosity is in the range of 10-30%. Inverse Laplace transform of 3He longitudinal magnetization recovery curve has been carried out, thus distribution of relaxation times T1 has been obtained.
