This invention discloses a method for establishing a development map and a development method for low-abundance, low-permeability tight sandstone gas reservoirs. The map establishment method includes: S1, selecting typical well areas and using multi-factor sensitivity analysis to determine the main controlling factors affecting recovery rate; S2, using dynamic and static methods to establish the relationship between net profit and recoverable reserves for different well types under different economic policies; S3, using typical well areas to predict the recoverable reserves of gas wells under different recovery rate controlling factors, and combining the relationship between net profit and recoverable reserves to obtain the relationship between different controlling factors and net profit, i.e., the gas reservoir development map. A dynamically changing development potential evaluation model is established by combining the map and the gas reservoir numerical model. This model can quantitatively predict and evaluate the development potential of gas reservoirs from production to abandonment at any time, in any well area, and in any gas layer under different economic and technological policies, realizing real-time dynamic evaluation of the development potential of gas reservoirs.
