摘要
目前我国已经开始大规模兴建盐岩能源地下储库群,客观存在的不确定性因素使得盐岩地下储气库不可避免地存在风险,因此开展盐岩地下油气储库风险分析研究具有重要的理论意义和工程应用价值。本文探索基于可靠度的随机力学方法在盐岩地下储气库工程中的应用,以金坛盐岩地下储气库为研究对象,基于可靠度随机力学分析方法对盐岩地下储气库的可靠性进行分析,建立了盐岩破坏的功能函数,探讨其在不同储气内压下,在材料强度参数为随机的情况下盐腔可靠性的变化规律,经过计算指出储气库薄弱部位,为储库安全运营提供技术依据。
Energy storage is in great demand for the national strategy,large-scale underground salt-rock storage constructions have begun in China.Objective uncertainties cause unavoidable risk in underground saltrock gas storage.Therefore,it is very significant to develop an effective risk analysis technique in underground saltrock gas storage.In this paper reliability-based stochastic mechanism method was used in risk analysis of Jintan underground saltrock gas storage,the failure mode performance function was established,the reliability index variation law of saltrock gas storage was obtained under different gas pressure when the strength parameters were considered as the random parameters.The weak part of the gas storage was pointed out through calculations,which can provided scientific basis for gas storage safety operation.
