The invention provides an intelligent analysis decision-making system for controlling well drilling, which divides a well drilling process into set intelligent points according to well area data and well drilling requirements, sets input parameters and decision-making related parameters for each intelligent point, obtains data contents corresponding to all the intelligent points according to setting results of each parameter, and sends the data contents to the intelligent points. After preprocessing, a set management strategy is adopted to carry out data storage and visual display, then a set intelligent analysis and diagnosis model is utilized to analyze and determine diagnosis information representing the real-time state of the drilling well, and the intelligent degree of each intelligent point is evaluated and graded; a matched intelligent control mode is decided according to the data content of each intelligent point and the intelligent degree evaluation result, and a drilling equipment control instructio
