Key words: low-permeability formation, nonlinear filtration, equation piezoconductivity, laboratory experiments.

The laboratory experiments on nonlinear filtering of water and oil in stationary and non-stationary. The numerical simulation restored according filtration rate over the entire range pressure gradients. Obtained correlations between the parameters of nonlinear filtering of water and oil and absolute permeability of the reservoir.
