工作井数对含水层压缩CO2储能系统季节性运行的影响
Effect of the Number of Working Wells on the Seasonal Operation of the Compressed CO2 Energy Storage System in Aquifers
摘要
Abstract
To clarify the influence of the number of working wells on the operational performance of sea-sonal aquifer compressed CO2 energy storage systems,three three-dimensional numerical models of well groups-gas storage reservoirs with different numbers of working wells(9,5,and 3)were established.The T2WELL numerical simulation software was used to investigate the seasonal cyclic operation process of the energy storage system under different numbers of working wells.The results showed that when the number of working wells decreased from 9 to 3,the maximum pressure at the wellhead of the central well increased from 17.42 MPa to 18.23 MPa,and the maximum temperature at the wellhead of the central well rose from 59.21℃to 60.18℃.The maximum energy efficiency of the energy storage system droped from 1.028 55 to 1.027 74.This indicates that the number of working wells significantly affects the CO2 migration pattern and pressure/temperature transfer process within the wellbore-forma-tion system.Therefore,in practical engineering,the number of working wells can be increased to reduce the pressure/temperature during the injection stage of the energy storage system's cyclic operation,there-by enhancing the energy efficiency of the energy storage system.关键词
