Abstract:
     The present invention relates to a method for continuously automtically measuring oil-water phase splitting flow at the time of micro flow of oil-water mixture. Said method uses a special-made connector, and uses the continuous measurement of voltage variation of the resistor fixed on the loop so as to obtain its oil-water flow ratio, and then combines it with the fluid weight flow measured by elecronic balance, and then according to the densities of oil and water it can calculate the oil and water phase-split flows. Said invention is high in automation degree, accurate in measurement and large in data capacity, so that it is applicable to automatic continuous measurement of various relative permeabilities (stable state, unsteady state, two-phase and three phase) and core flow tests.
