The influence of rock heterogeneity on stability well walls

In the proposed work, the problem of determining the fracturing pressure is considered, taking into account the heterogeneity of rocks. The work can be divided into two parts. In the first part, the physical properties of porous bodies in contact with a liquid were investigated, taking into account them as a two-phase medium. When a porous body comes into contact with liquids, liquids penetrate them, turning them into a two-phase medium. By liquid, we mean both liquids and gases. We will consider real liquids incompressible, and gases highly compressible. The rest of the porous body, with the exception of the pores, will be called the skeleton. Pores in porous bodies communicate with each other through capillary tubes. Keywords: heterogeneity, reduced value, pore, physical properties, well walls, fracture condition, critical value, hydrostatic pressure.
