METHOD AND DEVICE FOR CONTINUOUSLY MEASURING VARIATIONS IN THE OVERALL SATURATION OF A SAMPLE IN NON-MISCIBLE INCOMPRESSIBLE FLUIDS

摘要

The saturation variations are obtained by displacing a first fluid (water for example) which initially saturates a sample (1) embedded in resin (2), by injection into it through a first plate d 'nozzle or cap (3), and by means of a pump (7), a second fluid (oil for example). The mixture leaving through an opposite end plate (4) is collected in a two-phase separator (9) initially filled, placed on an electronic balance (10) The first excess fluid flowing to a container (13) , the progressive accumulation of the second fluid in the separator (9), varies the total mass. A programmed processor (14) continuously calculates the saturation values of the sample with respect to the first and second fluid, from the measured variations in the mass of the separator (9). BR/ Application to laboratory measurements on rock samples, for example.
