Evaluation on standardized methods of original relative permeability curves

A lot of different relative permeability curves are provided from the laboratory. The representative relative permeability curve is obtained by standardized processing. However, no one correlates the result of each method with the production characteristics and oil-water movement law of actual oilfield to illustrate the rationality and validity of the each method. According to the problem, we study the standardization results of each method combining with the actual field performance and from the water cut rising rules, oil displacement efficiency and oil recovery. Results show that the relative permeability curve determined by the standardized curve method of mean curve is in accord with the seepage characteristics of actual reservoir.
