Abstract
The article is devoted to determining the filtration parameters of an oil reservoir by the method of filtration pressure waves. The application of the method in laboratory conditions in the case of rectilinear-parallel filtration is considered. A laboratory installation for studying samples of porous media with an automated laboratory-experiment control system is described. The installation allows one to examine samples up to 145 × 10 × 6 cm3 in size, setting the liquid flow rate, which varies according to a harmonic law with periods of exposure from units of seconds, and measuring pressures at various points in the sample. Based on the time series of the flow rate and pressure obtained, the sample piezoconductivity can be calculated with an error of 3%. The results of an experimental study of sand using the installation and calculation of the piezoconductivity are presented.
