Deduction on Equation of Water Ratio in Oil with Microwave Method

Based on the basic principle of microwave double-parameter method to survey water ratio in oil and by established oil-gas-water three-phase complex permittivity model, the relationship between energy storage factor and loss factor with the density of mixed liquid is studies. The microwave transmission method for water ratio in oil that can eliminate density influence for the mixed liquid is given, and function expression for water ratio and microwave transmission parameters is deducted.
