| Zusammenfassung: | The invention discloses a method for determining the optimal oil nozzle size of a tight oil volume fractured well. The method comprises the following steps: S1, obtaining basic data of a target well; S2, determining the reasonable oil nozzle size of the target well; S3, calculating liquid production indexes and oil production indexes under different reasonable oil nozzle sizes, wherein the oil nozzle size corresponding to the maximum liquid production index and oil production index is the optimal oil nozzle size; S4, calculating the decline yield; S5, calculating the accumulative liquid production capacity under different reasonable oil nozzle sizes; S6, calculating the accumulated oil production under the single oil nozzle size; S7, determining the size of the oil nozzle combination; S8, calculating oil production indexes under different oil nozzle combination sizes; and S9, calculating the accumulated oil production under different oil nozzle combination sizes, wherein the oil nozzle combination size corres |
