Zusammenfassung:The invention discloses a gas well effusion early warning method, system and device and a storage medium. The method comprises the steps that S1, the bottom hole flowing pressure is obtained through calculation; s2, the bottom hole flowing pressure, the gas-liquid ratio and the yield are fitted to form an early warning drawing board, and the bottom hole flowing pressure and the gas-liquid ratio are the horizontal coordinate and the vertical coordinate of the early warning drawing board respectively; and S3, establishing a relationship between the yield and the bottom hole flowing pressure through an IPR curve, simulating a relational expression of the bottom hole flowing pressure, the formation pressure and the yield through cyclic derivation, calculating the allowable maximum bottom hole flowing pressure, taking the allowable maximum bottom hole flowing pressure as an early warning value of the gas well effusion, and marking the value on an early warning drawing board. The gas well accumulated liquid can be
