Combination application of waterflooding curve and relative permeability curve to calculate the geologic reserves of different typed wells;

Calculation method of relative permeability curve in low permeability reservoir;

Application of oil-water relative permeability curve and dynamic data to defining waterflood sweep situation;

Based on the actual practice of Longdong Oilfield, the oil-water relative permeability curve were measured according to the oil and gas industry standard of China SY/T 5345-1999"Methods for Measuring Non-stable Oil-water Relative Permeability".

Wettability affects relative permeability curves because it is a major factor controlling the location, flow, and spatial distribution of fluids in the reservoirs.

Based on the analysis of the relative permeability curves in Sa-zhong area,the characteristics of these curves have been given in this paper,it includes the conformation of curves,the interval of water saturation between which oil and water can both flow,water saturation at isopotal point.
