摘要/Abstract

摘要：为了探究储层岩石力学响应对含水层压缩空气储能（CAESA）系统储能效率的影响，利用数值模拟程序T2WELL/EOS3-FLAC3D对比分析了不同注气温度、渗透率、注采速率条件下，传热-流动-力学耦合和传热-流动耦合的CAESA系统储能效率.研究结果表明，因系统作业而产生的储层岩石力学响应会加速系统内的能量交换，考虑岩石力学过程后，系统储能效率下降速率加快；注气温度越高，储层岩石力学响应对储能效率的影响就越弱；在额定储能规模下，储层岩石力学响应对系统储能效率的影响存在渗透率阈值效应；注采速率越大，储层岩石力学响应对系统储能效率的影响就越强.

Abstract: In order to explore the influence of rock mechanical response of reservoir on energy storage efficiency 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,permeability,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 mechanical response of the reservoir to the system energy storage efficiency exhibits a permeability threshold 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.

Key words: compressed air energy storage in aquifer, energy storage efficiency, thermal-hydrologic-mechanical, thermal-hydrologic, couple
