Zusammenfassung:	The invention relates to a method for establishing an oilfield exploratory reserve quality quick evaluation chart. The method comprises the following steps: a, collecting data of stratum crude oil viscosity, reservoir permeability and exploratory reserve unit reserve scale of an exploratory reserve unit in a to-be-evaluated oilfield; b, establishing a rectangular coordinate graph, and taking stratum crude oil viscosity as an abscissa and reservoir permeability as an ordinate; c, setting the horizontal and vertical coordinate axes in the step b as logarithm coordinate axes to obtain logarithm horizontal and vertical coordinate axes; d, taking different horizontal and vertical coordinate values from the logarithm horizontal and vertical coordinate axis to obtain a cross plot model; and e, carrying out statistics on the stratum crude oil viscosity, reservoir permeability and exploratory reserve unit reserve scale of the exploratory reserve unit in the to-be-evaluated oil field in the stepa, putting the stratum c
