Method of determining the components of an effective permeability tensor of a porous rock |
摘要 |
The invention is a method of determining all the components of an absolute permeability tensor of a porous medium sample from permeability measurements, obtained for example by placing the sample in a permeameter which is useful for fast determination of permeability anisotropies of rocks and detention of internal heterogeneities. A pressure difference DeltaP is applied between the inlet and outlet faces of a laboratory rock sample, with zero flow conditions on the edges parallel to the mean flow obtained by confining it in a sheath under pressure. Starting from conventional permeability measurements in three directions and from the measurements of the two components of the viscous forces transverse to the sample, permeability tensor k can be "inverted" by numerical solution of the corresponding boundary-value problem. Since these quantities can be alternatively obtained from numerical solutions of the same flow in a heterogeneous medium, the method can also be used as an upscaling tool in a reservoir simulator.
