Modeling of oil filtration processes near production well

On the base of combined finite element -difference method, we carried out computer modeling of the oil filtration processes in the vicinity of oil production well. According to obtained results, intensity of filtration process near the acting oil production well mainly depend on oil phase permeability, as in close zone (Ra < 5m) so remote zone (Ra > 5m) of well action. At that, influence of oil permeability in remote zone more effective than influence in close zone of production well action. The oil viscosity and oil reservoir porosity parameters in close and remote zones of the well action have little direct effect on filtration process near the acting well. However, these parameters can influence on the filtration process via acting on the oil phase permeability. Analysis of the pumping well influence on the filtration process near oil production well in different practical cases shows that for stable supporting quite high pressure in vicinity of oil production well at the low oil phase permeability it is necessary using of pumping well.
