The invention provides a multi-period non-continuity hydrocarbon potential evaluation method for a superimposed basin, and the method comprises the steps: 1, building a stratigraphic framework, and evaluating the distribution condition of the overlying strata of hydrocarbon source rocks; 2, analyzing the structural evolution history of the basin, and carrying out the dividing of a structural evolution unit; 3, calculating the denudation quantity of an overlying denudated stratum of the hydrocarbon source rocks, and carrying out the prototype basin layer by layer; 4, determining the burial history, geothermal history and hydrocarbon generation history of the hydrocarbon source rocks through employing the above analysis result and combining with the basin simulation technology, and determining a secondary hydrocarbon generation mode; 5, calculating the hydrocarbon generation quantities of a construction unit in different periods, evaluating the modern hydrocarbon generation capability, and determining a beneficial secondary hydrocarbon generation center. The method provided by the invention is clear in thinking, is simple in application, and is feasible for the evaluation of the hydrocarbon potential of the multi-period non-continuity hydrocarbon source rocks.
