Zusammenfassung:The invention discloses a risk assessment method of out-of-control blowout in deep water drilling, comprising the steps of: S1, selecting influencing factors of out-of-control blowout in deep water drilling, dividing the corresponding influencing factors into layers, and constructing a risk evaluation system of out-of-control blowout in deep water drilling; S2, calculating the weights of each influencing factor in the risk evaluation system of blowout out out of control in deep water drilling; S3, formulating evaluation indexes of each influencing factor, and constructing risk evaluation standards of the influencing factors; S4, evaluating each influencing factor according to the risk evaluation standard of each influencing factor, and calculating the quantitative result of out-of-controlblowout risk of deep water drilling according to the evaluation result and the weight of each influencing factor. Through the selection of influencing factors, the establishment of evaluation system,the calculation of weights
