The study is concentrated on the analysis of the interaction between oil wells and water-induced hydraulic fractures. The problem is considered in terms of theory of poroelasticity, hydrodynamics and fracture mechanics. The hydrodynamic aspect of the problem is divided into two types: oil displacement by water injected and the study of water behaviour inside the fracture itself. Numerical modelling was used for solving the problems. A two dimensional problem of Perkins-Kern fracture propagation in a permeable medium is considered. The basic equation of piezoconductivity is used to describe the process of filtration outside the fracture with the boundary conditions defined by “well-formation” system. The proper pressure distribution in the fracture is determined from the solution of continuity equation and Navier-Stokes equation in one-dimensional form. Fracture is considered to be propagating perpendicular to the direction of the lowest principal stress which is determined by several factors analysed in the research. The paper suggests a method for considering the dynamic process of fracture propagation. This result can be further used to predict the water-induced hydraulic fracture geometry while planning the development of an oil field. |
