    Abstract
  • When drilling and completing reservoirs of high oil saturation, water base fluids will diffuse into the near wellbore region and gradually mixed with oils in the near wellbore area during production. Under some conditions this process will lead to oil/water emulsification which further causes reservoir damage. For reservoirs with low oil saturation drilled with oil base drilling fluids, oil filtrate from the drilling fluids will also diffuse into the near wellbore region, resulting again oil/water emulsification in subsequent production. A mathematical model was established to predict reservoir damage caused by oil/water emulsification based on hydrodynamic instability. The time-distribution, spatial distribution and change of reservoir damage by oil/water emulsification was obtained using this model. The reach of reservoir damage, although is confined within several tens of centimeters around the wellbore, serious permeability impairment results in high skin coefficient. This numerical model, in which the breakdown and dispersion of oil/water interface at low interfacial tensions and high shear rates were hydrodynamically analyzed, and the pore distribution of reservoir rocks and blocking by emulsion drops were taken into account in the simulation, has provided, to some extent, time and spatial simulation and diagnosis of reservoir damage by oil/water emulsification.
