Estudo numérico da produção de óleo em reservatórios petrolíferos via injeção de água.

Abstract

The exhaustion of reserves of oils, the heavy-oil has been given an important role in the generation of energy. Several researchers have been devoted to studies on the feasibility and economic exploitation of these reserves. The recovery method by water injection is one of the most widely used techniques for recovery and may employ different arrangements of injection and production wells. The purpose of this study is to evaluate numerically, by ANSYS CFX, the process of recovering heavy-oil in a porous media using a model of injection of five-spot. We are used the equations of conservation of mass and movement together with the law of Darcy. It was also considered the model for the particle flow biphasic water-heavy oil in porous media. Was used a uniform distribution for porosity and permeability. The results of the front of advance of water (volume fraction) toward the well from producing wells injectors are presented and analyzed.
