The paper presents the results of studying the influence of stresses on the permeability of different types of reservoir rocks in oil and gas fields. The investigations were carried out at the Triaxial Independent Load Testing Facility of the Institute of Problems in Mechanics of the Russian Academy of Sciences. It is established that the character of the dependence of the permeability on the acting stresses for different rocks can be significantly different. The results of the studies confirm the classification of rocks proposed earlier on their reaction to the change in the stress-strain state. The results of independent studies of recent years and their analysis with application of the proposed classification to the test results presented in the works are given. They also confirm the validity of the proposed classification.
