Reservoirs are influenced by incumbency rock pressure, sideways pressure and porosity pressure at primitive stratum. This stress state is called primitive effective-stress. After the primitive effective-stress be considered, the law of stress sensitivity still follow the negative exponential attenuation. Compare to no consideration of primitive effective-stress, the descend degree of permeability is more little, so the stress sensitivity is weaker. But the law can suit to the fact, and have practical meaning for actual production.
Key words： Effective-stress; Stress sensitivity; Reservoir; Permeability; Porosity.
