Generally, water production of natural gas well is important in the gas field development, and parts of production water of high temperature gas wells exist in saturated water vapor form, leading to measurement result deviation. In order to reduce the  water measurement result deviation of high temperature gas well production, it is necessary to calculate the saturation water content of natural gas and correct the deviation from production water measurement. Through the analysis of natural gas water content calculation method principle, and the contrast in the practical application effect of Y13 gas field, the method of semi empirical formula with theoretical derivation is suitable for the actual Y13 gas field. According to this method, the average deviation can be decreased from 60% to less than 6%. 
