High well head pressure，big well control risks，high bottom hole temperature，poor data stability and severe tubing damage etc.are the challenges existing in the operation of formation pressure monitoring and well productivity testing of abnormal high pressure gas reservoir which limits the application scale of conventional productivity testing.Through the research on the methods of gas well productivity evaluation，based on the bottom hole flow pressure determined by well head oil pressure while considering the dynamic parameters to evaluate the single well productivity using the dynamic production data of gas field and on the basis of this to calculate the gas well formation pressure P，laminar flow coefficient a，turbulent flow coefficient b，the gas well deliverability equation was established to evaluate the real-time productivity of gas field and to determine the reasonable productivity of single well and reasonable production of gas field.The application example shows that the relative error of AOF is only 2.75% between gas well absolute open flow(AOF) confirmed by surface dynamic production data and AOF measured by actual bottom hole pressure which proved the rationality of evaluation of gas well productivity by using of surface dynamic production data.Application of this new method not only saves testing operation cost and eliminates the testing risk，at the same time it provides a scientific basis for gas reservoir dynamic analysis，tracking data simulation and gas reservoir management，and offers reference and guiding suggestion for similar abnormal high pressure gas reservoir development.
