The invention discloses a method and device for determining the sufficient energy limit of an anticlinal oil reservoir. The method comprises the following steps: determining geological data and development data of an anticlinal oil reservoir; determining at least one piece of annular well row data according to the supply edge radius in the geological data, the oil well row distance in the development data and the number of oil wells in each annular well row; determining the flowing bottomhole pressure of each annular well row according to the geological data, the development data and the data of each annular well row; and determining an energy sufficiency limit of the anticlinal reservoir based on the flowing bottomhole pressures and flowing bottomhole pressure thresholds in the development data. By executing the scheme, whether the oil reservoir can completely depend on natural energy development or not can be accurately determined, and the oil reservoir energy insufficiency range is determined. 本发明公开了一种背斜油藏
