THM耦合作用对CAESA系统储能效率的影响
Influence of THM Coupling on Energy Storage Efficiency of CAESA System
摘要
Abstract
In order to explore the influence of rock mechanical response of reservoir on energy storage effi-ciency of compressed air energy storage in aquifer(CAESA)system,the program T2WELL/EOS3-FLAC3D numerical simulation is used to analyze the energy storage efficiency of the thermal-hydrologic coupled and thermal-hydrologic coupled CAESA system under different injection temperature,permea-bility,injection-production rate.The results show that the rock mechanical response generated by the system operation will accelerate the energy exchange in the system,and the energy storage efficiency of the system will decrease faster when the rock mechanical process is considered.The higher the injection temperature,the weaker the influence of rock mechanical response on energy storage efficiency.The me-chanical response of the reservoir to the system energy storage efficiency exhibits a permeability thresh-old effect under the rated energy storage scale.The greater the injection and production rate,the stronger the influence of rock mechanical response on the energy storage efficiency of the system.关键词
