The productivity of gas wells in conventional gas reservoirs is mainly measured by open flow rate. The open flow rate is determined by gas test and production test data to evaluate the productivity of gas wells. Because of the particularity of geological characteristics and seepage mechanism

it is controversial to use which indexes to characterize the productivity of shale gas wells. Combined with the testing and production data of actual shale gas wells in China

it is proposed that the productivity of shale gas wells in different development stages can be characterized by three kinds of indexes—unhindered flow rate

recoverable reserves and gas production. When the productivity of shale gas wells is characterized by open flow

the empirical formula of

“one point method” in Fuling main area is established

and the reservoir capacity（

α

） is 0.25. For the production capacity test of multiple work systems

the multi-flow method has better adaptability in Fuling. When the productivity of shale gas wells is characterized by recoverable reserves

before shale gas wells enter the decline stage

the unsteady productivity evaluation method of shale gas fractured horizontal wells is selected; while after entering the decline stage

the recoverable reserves of shale gas wells can be predicted by empirical decline method. For shale gas wells with fixed production

the gas test production of the same oil nozzle can be optimized to characterize the productivity of shale gas wells. The research results lay a foundation for the dynamic analysis of shale gas well production and the formulation of development technology policy.
