APPARATUS FOR MEASURING THE RELATIVE PERMEABILITY OF A CORE HAVING A SATURATION MEASURING UNIT, AND METHOD FOR MEASURING THE RELATIVE PERMEABILITY OF THE CORE USING THE APPARATUS

摘要

The present invention relates to an apparatus for measuring the relative permeability of a core having a saturation measuring unit, and to a method for measuring the relative permeability of the core using the apparatus. The apparatus for measuring the relative permeability of the core includes: a core holder sealing and accommodating a core sample which is the target object for which permeability is measured; a first storage bath connected to the core holder to supply a first fluid into the core holder; a second supply tube connecting the core holder to a second storage bath to supply a second fluid received in the second storage bath into the core holder; a manometer for measuring the difference in pressure of the fluids between the front end and the rear end of the core sample in the direction of the flow of the fluids; a saturation measuring unit for measuring the saturation of the first fluid within the core holder and connected to the core holder so that the first and second fluids are separately received in order to measure the amount of the first fluid when the first and second fluids discharged from the core holder are introduced, the first fluid is discharged into the first storage bath so that the first fluid circulates, and the second fluid is discharged through a path different from that of the first fluid.
