A method and system for predicting a maximum build rate of a push-the-bit rotary steering tool is provided. In the method, a mechanical mathematical model of a push-the-bit rotary steering device is combined with measured well inclination data of the rotary steering device during actual drilling, a theoretical maximum build rate of a steering tool is calculated by the mechanical mathematical model, and a correction factor is combined with the mechanical mathematical model to predict a maximum build rate of the steering tool during a drilling operation in a same layer of a same block. The method effectively solves the problem of predicting the maximum build rate of the push-the-bit rotary steering device with different parameter changes based on measured data. Therefore, the method and system provide a reliable means for operators to analyze the performance of the push-the-bit rotary steering device, thereby providing technical support for efficient drilling operations.
