The Effect of Relative Volume Percentage of Movable Fluid on Development Effects of Low Permeability Reservoir

Abstract

Abstract: Relative volume percentage of movable fluid of more than one hundred of super-low permeability core samples is tested by using nuclear magnetic resonance technique. The results indicate that there exist good correlation between the percentage and permeability and oil displacement efficiency. The higher permeability, the bigger the percentage is, except for low permeability condition; the bigger the percentage, the higher the oil displacement efficiency is. Based on these, this paper suggests the classifying criterion of reserves by the relative volume percentage of movable fluid, by which the development effects of low permeability reservoirs between Daqing and Changqing fields are analyzed and correlated.

Key words: movable fluid, relative volume percentage, low permeability reservoir, development effect, nuclear magnetic resonance
