Abstract: A mathematical model of pressure buildup testing analysis for gas-water well is presented in the paper, and the mathematical model is simplified by defining a function of gas-water two-phase pseudo-pressure. Based on the obtained solution of the mathematical model, an analysis method for pressure buildup data of gas- water is established. Practical pressure buildup testing data of a gas-water well were explained, and reservoir permeability, skin factor and reservoir pressure obtained, from which the results are reliable, thereby it is proved that the analysis method presented in the paper is reasonable.
