Аннотация
The problem of unsteady bilinear flow of a single-phase Newtonian fluid in a formation with a finite auto-fracture connecting an injection and production well is considered. The wells simultaneously begin to operate at constant pressures in an initially undisturbed infinite formation with a vertical main fracture of constant width. Using the Laplace transform method, analytical solutions were obtained for the pressure fields in the fracture and formation, as well as the flow velocity in the fracture. An approximate model is considered that uses a self-similar solution to the problem of filtration of an incompressible fluid in an elastic half-space with constant pressure at the boundary to simulate filtration leaks. It was found that for a number of model parameters a simple analytical solution of the approximate model gives acceptable results.
