Gas well safety risk grading early warning method and system, electronic equipment and storage medium

The invention discloses a gas well safety risk grading early warning method. The method comprises the following steps that A, the basic risk grade of a high-sulfur-content production gas well is determined based on a well barrier integrity evaluation result; b, constructing a key parameter early warning model, generating alarm data through process parameters and leakage parameters obtained in real time, performing statistical analysis according to historical alarm data, and calculating an early warning value TAlarm; c, determining a corresponding correction coefficient gamma R according to the basic risk level; determining a key parameter early warning index TR according to the early warning value TAlarm; and D, constructing a risk early-warning grade index calculation model, and calculating the safety production risk early-warning index of the high-sulfur-content gas well through the correction coefficient gamma R and the key parameter early-warning index TR. The invention further discloses a gas well safety
