Conclusions

  1. 1.

    The problem of equilibrium between liquid and gas filling a porous medium was formulated.

  2. 2.

    A model of a porous medium, considering both the change in the cross section of the pores along their length and their intersection, with the intersection of pores taking the form of three-way junctions, was formulated.

  3. 3.

    A method of cycles representing a method of calculating the probability of filling according to parts was proposed to calculate the conditional probability of filling of a pore with a gas under the condition that this pore is supercritical.

  4. 4.

    Equations were derived for all cycles, and a function relating the final summary probabilities of filling of the pores and junctions was obtained.
