Abstract: Primitive oil一bearing saturability of oil layers is a very important parameter of reservoir appreciation and reserve volume calculation. This paper presents a comprehensive study method，taking into account the factors，such as dry capillary pressure，permeability devo-tion value，permeability一absorption test，minimum throat radius，oil column height，perkmeability ratio curve，logging data interpretation etc. So far this method has been used to
calculate the primitive oil-bearing saturability of reservoirs in some region.

Key words: Parameter of reserve volume calculation, Capillary pressure, Permeabilitydevotion value, Throat radius, Primitive oil-bearing saturability
