摘　　要：为了充分利用储气库注采站的流量与压力潜能,提高能量利用率,提出将天然气压差发电技术应用于储气库中。在注采站中嵌入压差发电机组,建立耦合水热力下嵌入压差发电的储气库系统低碳运行优化模型,设计了启发式循环优化求解流程,并结合BARON求解器实现对优化模型的求解。某储气库的算例结果表明:嵌入压差发电机组后,储气库的运行碳排放量均比嵌入前低,同时压差发电机组又可额外降低碳排放量,减碳效果显著。此外,对比压差发电机组嵌入前后在不同运行方式下的运行能耗与发电参数,分析了降压运行方式下储气库的注采方案和储层参数,有助于确定储气库系统最优的运行策略,为推动嵌入压差发电机组的储气库低碳运行发展提供指导。To make full use of the flow and pressure potential of the gas storage injection-production station and improve the energy utilization rate,the natural gas differential pressure power generation technology is proposed to be applied to the gas storage.The differential pressure power generation set is embedded in the injection-production station,and a low-carbon operation optimization model of the gas storage system with embedded differential pressure power generation under hydro-thermal coupling is established.A heuristic cyclic optimization solution process is designed,and the optimization model is solved in combination with the BARON solver.The example results of a gas storage show that after embedding the differential pressure generator set,the operational carbon emission of the gas storage is lower than that before embedding,and the differential pressure generator set can additionally reduce the carbon emission,which makes the carbon reduction effect significant.In addition,comparing the results of energy consumption and power generation parameters before and after embedding the differential pressure generator set under different operation modes and analyzing the injection-production scheme and reservoir parameters of the gas storage under the reduced-pressure operation mode are conducive to determine the optimal operation strategy of the gas storage system,which provides guidance for promoting the development of low-carbon operation of gas storage with embedded differential pressure generator set.
