Porous medium`s electrical resistivity and flow parameter e.g. relative permeability, evaluating method for study of oil reservoir, involves estimating parameter from differential pressure of sample and curve of fluid output volume

摘要

The method involves continuously measuring, in function of time, electrical resistivity of a solid porous sample (S) and differential pressure between two ends of the sample. The fluid output volume displaced at stabilization bearings is measured, and a relation between the resistivity and the volume is estimated. A continuous curve is established for the volume in function of time from the relation. Flow parameters are estimated using a digital flow simulator from continuous measurement of the pressure and the curve. An independent claim is also included for a device for executing multi-rate displacement experiment on a solid porous sample.
