摘 要:针对地下储气库扩容达产阶段压力、库存及地层流体流动多处于不稳定状态等特征,在常规节点压力系统分析进行配产配注的基础上,结合注采气能力主控因素,建立了以井为单元、立足于单周期的配产配注综合方法。研究表明:扩容达产阶段配产 配注应以井周期修正注采气能力为基础,以不稳定流动井控库存、宏观注气速度等为约束条件,亦即考虑井控范围物质平衡和稳定 气水界面,从而达到最优的气驱扩容效果和最大有效库容。该方法具有普遍适用性,可用于计算储气库扩容达产阶段周期注采气 能力,为确定储气库注采方案关键指标提供快速、有效的方法;同时,也可用于对比评价已运行储气库注采指标的合理性。关键词:地下储气库;扩容达产;配产配注;模型

A comprehensive method of production and injection afocction with welts as unit is established in single cycle , based on the analysis of conventional nodal pressure system and the main control factorr of injection and production capacity. The re -sults show that production and injection allocation at the stage of capacity expansion and production should be based on the well cycle correc -tion gas injection and production capacity , with the constraints of unstable flow well control inventoo and macro gas injection speed , i. e. considering the material balance of well control onge and stable gas-water interface , so as to achieve the optimal gas drive capacity expan -sion e —ect and maximum effective reservoir capacity. This method has universal applicability and can be used to calculate the cyclic gas in -jection and production capacity of gas stooge in the stage of capacity expansion and production. It provides a fast and effective method for determining the operation index of gas storage. At the same tirne, it con also be used to compare and evaluate the rationality of the injection and production index of the gas stooge in operation
