A method and an apparatus for evaluating preservation conditions of shale gas

A method and an apparatus for evaluating preservation conditions of shale gas are provided to solve that problem that the importance of each evaluation parameter to the preservation conditions of shale gas cannot be determined in the prior art. The method comprises the following steps of: obtaining evaluation parameter values of each preset index of each shale gas well in a plurality of shale gaswells with respect to a plurality of preset indexes; obtaining a weight of each preset indicator of a plurality of preset indicators; calculating all objectively existing shale gas preservation condition comprehensive evaluation standard values and shale gas preservation condition evaluation standard division limit values according to a shale gas preservation condition evaluation equation constituted by the plurality of preset indexes and weights of each preset index of the plurality of preset indexes; according to all objectively existing comprehensive evaluation standard values of shale gaspreservation conditions, o
