Simulations of an invaded zone in borehole drilling
The evolution of an invaded
zone drilling in water- and
oil-saturated sand formations
is studied by mathematical
modelling of hydrodynamic
processes in porous media
filled with a two-component
fluid. The use of hydrodynamic
modelling to interpret high-
frequency electromagnetic logs makes it possible to construct consistent geoelectric and hydrodynamic models for
formations with different fluid saturations.
C-salt concentration, S - water saturation, v(t) - rate of drilling, k(z) - permeability,H – hydrodynamic head
