The invention provides an optimization method for shale reservoir exploitation, and belongs to the technical field of oil and gas exploitation. The optimization method for shale reservoir mining comprises the following steps of setting at least two sets of injection and mining parameters, wherein the injection and mining parameters comprise liquid injection time, liquid injection amount and well closing time; according to a pre-established flow model, determining a predicted yield corresponding to each set of injection and mining parameters; and selecting an injection and mining parameter forproduction according to the comparison result of the predicted yield. According to the scheme of the optimization method, reasonable mining data guidance can be provided for actual shale reservoir mining. 本发明提供一种用于页岩储层开采的优化方法，属于油气开采技术领域。所述用于页岩储层开采的优化方法包括：设定至少两组注采参数，所述注采参数包括注液时间、注液量和闷井时间；根据预先建立的流动模型确定每组所述注采参数对应的预计产量；以及根据所述预计产量的比较结果，选定用于生产的注采参数。通过本发明提供的上述方案，能够为页岩储层实际开采提供合理的开采数据指导。
