Abstract: 
In the present study the process of hydraulic fracture formation when pumping a viscous fluid with an admixture of particles into a well is considered. A model of a crack propagation taking account of the loss of liquid on seepage into a porous medium and the sedimentation of suspended particles under the action of gravity is developed. Detailed analysis of the sedimentation growth caused by leakage of hydraulic fracturing fluid into a p orous medium is carried out. It is shown that the presence of particles has a significant effect on the process of crack opening. The crack growth in the presence of particles is limited, its final state depends on the composition of the mixture, injection method, inlet pressure, the volume content of the particles, the volume of the rim (pure fracturing fluid without admixture). All these factors are taken into consideration in the proposed model based on special dimensionless forms of the equations of motion. The results make it possible to estimate the crack residual and choose t he technological parameters to provide the desired state of t he ruptured formation.
