Abstract

Abstract:

Aiming at the characteristics of consolidated model,a set of saturation measurement system for consolidated 3-D reservoir physical simulation is set up by considering the practical conditions of high temperature and high pressure.The principle of resistance measurement is adopted to determine saturation,a micro-probe is selected finally by evaluating multiple materials and samples.The following key problems are solved and the related technologies formed,saturation measurement technology for consolidated 3-D physical simulation and high temperature and high pressure,the technology for external sealing of internal model saturation traverse lines.At last,the measurement system is employed to carry out 3-D physical simulation of polymer flooding.The macro mechanism of flowing through porous media of enhancing oil recovery by polymer flooding is studied with recovery curve of polymer flooding and the plot of saturation field.

Key words: micro-probe, saturation, reservoir physical modelling, measurement, experimental research
