The calculation of single well dynamic reserves in condensate gas wells has been a hot and difficult problem in the field of exploration and development of condensate gas reservoirs.The conventional calculation methods,such as single-phase method based on the material balance equation of dry gas reservoir,have many limitations,which result in the calculation error of single well dynamic reserves.Therefore,on the basis of theoretical research,the unsteady flow equations of gas phase and condensate oil are established based on multiphase flow theory.By introducing the mass conservation equation in production process and combining with the total quality of the collected data,the production history fitting optimization model is established by combining with the production data to ensure the accuracy of the reserves calculation results and the example is validated.It is concluded that the new method is based on the principle of mass conservation and fully participates in the calculation of gas well production data,which guarantees the accuracy of the evaluation results of single wells dynamic reserves in condensate gas wells.
