| titleOfInvention | Method for determining the stress-strain state of a stratified medium |
| abstract | The present invention relates to methods for determining the stress-strain state of stratified media with at least one poroelastic layer, which is filled with a liquid or a gas, in the event of a change in the pressure of this liquid or gas and can be used in particular in the oil and gas industry. When implementing the method: a) the starting parameters of the stratified medium are determined, b) the load, distributed volumetrically, on the investigated layers of the stratified medium is determined, c) a system of equations is created, including: equations for the elastic equilibrium for each layer, equations determining the boundary conditions at the layer boundaries, namely the continuity of the stresses between the layers, the zero stresses at the free boundary, the zero shifts to infinity, d) analytical solutions to the equations relating to the elastic equilibrium in each layer are produced on the proviso that the layers are planar-parallel, homogeneous and poroelastic, e) the analytical solutions produced in the different layers are correlated with one another taking into consideration the relevant boundary conditions, and f) the values for the stress and the shift at selected points in the medium are determined according to the required approximation accuracy on the basis of the correlated analytical solutions. The technical result consists in the high speed of the method whilst producing a high level of accuracy of the desired values. |
