摘要：
A simplified analytical expression for the capillary pressure gradient in homogeneous porous media is proposed. Basic assumptions are: (1) the three phase contact angle between two fluids and porous rock is finite, (2) the surface area of contact between two fluids is small in comparison with contact surface areas between each fluid and porous rock in the unit volume of the system under consideration, (3) the model corresponds to conditions when both phases are continuous.
