摘要

Laboratory experiments on a low porous sandstone (Flechtinger Bausandstein) were performed to investigate the influence of pore pressure change on reservoir properties during production and injection of fluids. The triaxial experiments under uniaxial strain boundary condition show that pore pressure variations have a strong impact on porosity and permeability. The parameters decrease with decreasing pore pressure and are in addition dependent on the frequency of pore pressure variation.
