The invention provides a Rock drillability prediction method and system, a storage medium and an electronic terminal. The invention adopts the way of combining nonlinear regression and artificial neural network, firstly removes invalid logging variables and invalid logging parameters through monadic and multivariate nonlinear regression methods, and then establishes a calculation model for predicting rock drillability by using artificial neural network. This method has the advantages of simple calculation process, high accuracy of rock drillability prediction, strong stability and low cost, which is conducive to field popularization and application.
