Optimized method for determining physical parameters of a sample subjected to centrifugation |
摘要 |
A method for faster determination of physical parameters (capillary pressure curves and relative permeabilities for example) of a geologic sample initially saturated with a first fluid placed in a vessel and subjected to centrifugation in the presence of a second fluid. The equilibrium saturations are determined before complete stabilization is reached through analytic modelling involving exponential functions, best adjusting to an effective production curve, for each speed stage. A database, obtained by means of various simulations, is used to obtain the relative permeability curves corresponding to the centrifuged sample. The method can be applied for measurement of petrophysical characteristics.
