Abstract: When flowing material balance equation is applied in gas water coproduction volumetric gas reservoirs，as the water-gas ratio increases，the calculated dynamic reserves error gradually tends to increase，and the result affects the evaluation of gas well production potential. To address this problem，a gas-water two-phase material balance equation for volumetric gas reservoir was established by integrating the effects of water saturation， cumulative water production and rock matrix expansion.The results show that：（1）As the equation is an implicit function equation，a corresponding iterative solution method is designed to be constrained by dual parameters of dynamic reserves and pseudo-pressure gas recovery index.（2）Verified by the pressure recovery test results of 3 gas wells，under the same conditions of using wellhead and wellbore production data，the average absolute error of calculating dynamic reserves using the gas-water two-phase material balance equation is 5.0%，and the average absolute error of calculating dynamic reserves using the flowing material balance equation is 111%. By comparison，the accuracy of gas-water two-phase material balance equation is higher.（3）Dynamic reserves decrease as the water-gas ratio increases. And as the water-gas ratio increases，the difference of dynamic reserves calculated by the gas-water two-phase material balance equation and the flowing material balance equation becomes greater.

Key words: gas water coproduction volumetric gas reservoirs, tight gas reservoirs, dynamic reserves, pseudopressure gas recovery index, gas-water two-phase material balance equation, flowing material balance equation, Daniudi Gasfield, Ordos Basin
