摘要:
盐穴地下储气库井口设施一旦发生泄漏，即可能引发火灾或爆炸事故，因此研究盐穴地下储气
库井口火灾事故危险具有重要意义。采用喷射火危害模型分析了盐穴地下储气库井口破裂火灾事
故危险，建立了井口破裂模式下的气体泄漏率和损失气体体积的准瞬态计算模型，预测结果能够反
映井口破裂泄漏的实际情况。同时，基于热通量伤害准则，给出了危害半径的计算公式，分析了危害
半径与盐穴压力的关系，即灾害半径随盐穴运行压力的增加而增大，由此提出在储气库安全设计阶
段需要留出必要的安全距离，并制定相应的防范措施。该研究结论可为盐穴地下储气库泄漏后果评
估提供重要参数和技术支持，并可为减少事故损失提供理论指导。（表2，图3，参9）　　　
Abstract:
 Once leakage happens to the wellhead of underground salt cavern gas storage, it may lead to fire or explosion, so
it is of great significance to study on fire risk due to wellhead rupture at underground salt cavern gas storage. Spraying fire
damage model is employed to analyze the fire risk, and quasi-transient model of the leakage gas rate and lost gas volume
under the condition of wellhead rupture are established, and the prediction results can reflect the actual situation of the
leakage due to wellhead rupture. At the same time, based on the thermal fluxes damage principle, the calculation formula
of damage radius is worked out and the relation between damage radius and salt cavern pressure is analyzed, which shows
that the damage radius becomes larger as salt cavern pressure goes higher. Therefore, it is pointed out that essential safety
distance shall be kept in the safety design of gas storage, and corresponding preventive measures shall be set up. The study
can provide important parameters and technical support to the result assessment of leakage of underground salt cavern gas
storage. Besides, it can provide theoretical guidance to the decrease of accident loss. (2 Tables, 3 Figures, 9 References)
