Abstract:

The article offers an approach to tuning of heavy oil deposition model from weakly-cemented reservoir with geomechanic effects. This effects appear as changing permeability at the downhole zone near the injection well. Researchers think that the nature of low-density zones occurrence related to increasing of the resistance factor which is influenced with increasing of filtration velocity. High filtration velocity is caused by polymer flooding increasing. This work was made with basis on hydrodynamic model of the pilot area where are the experiments of displacement of heavy oil during polymer flooding. There are not only well history-matching but assessment of hydrodynamic model prediction ability. Keeping of geomechanic effects allows to achieve the adequate reproduction dynamic of fact bottom-hole pressure during polymer solution injection. Application of the given approach leads to uncertainty reduction and improved prediction reliability.
