The invention discloses a stratum brittleness index earthquake prediction method, electronic equipment and a storage medium. The prediction method comprises the steps of 1, predicting mineral contents of different minerals in a target stratum; 2, calculating the comprehensive toughness of the stratum based on the mineral contents of the different minerals; and 3, constructing a brittleness index prediction model based on the stratum comprehensive toughness, and predicting the brittleness index of the target stratum according to the brittleness index prediction model. According to the method, the brittleness characteristics of the stratum can be predicted more objectively, the shale gas exploration level is improved, and reference data are provided for well position deployment, horizontal well design, engineering fracturing and the like. 本发明公开了一种地层脆性指数地震预测方法、电子设备和存储介质，其中预测方法包括：步骤1：预测目标地层中不同矿物的矿物含量；步骤2：基于所述不同矿物的矿物含量计算出地层综合韧性；步骤3：基于所述地层综合韧性构建脆性指数预测模型，根据所述脆性指数预测模型对目标地层的脆性指数进行预测。本发明能够更为客观地预测地层的脆性特征，提高了页岩气勘探水平，井位部署
