Hydrodynamic analysis of the displacement conditions of formation fluids using an axisymmetric model
I. B. Chernoshchuk Lavrent’ev Institute of Hydrodynamics, Siberian Division, Russian Academy of Sciences, Novosibirsk, 630090
Abstract:
The axisymmetric problem of the displacement of formation fluids by a drilling mud filtrate with filter cake formation is considered. An analysis is made of the distribution and variation of the main parameters of the process: filtrate volume, filter cake thickness, oil saturation, and pressure. The positions of the water-saturation and salt-concentration fronts are determined. The results are compared with the geophysical logging data for straight-hole drilling.
Keywords:
invaded zone, oil saturation, salt concentration, pressure, filtrate volume, filter cake.
