Abstract: Kelameili volcanic gas field belongs to a high porosity and super-low permeability volcanic rock gas pool. It is of strong heterogeneity, vertically and laterally varied lithology and rock facies, unevenly distributed fractures and very complicated relationship between gas and water. The production performance varies from well to well, and the water production characteristics are complex. There exist uncertainties in the produced water source, mechanism and pattern. Based on previous studies, the water production problem in this gas field is researched using related methods available; the produced water source is figured out; the quantitative water production rates of different types are calculated by means of Mcketta?Wehe chart; the classification of produced water source type is conducted, and finally, the influences of different types of produced water source on the gas wells are analyzed in this paper
