摘要/Abstract

摘要：

地下盐穴储气库注采周期的变化会导致腔内气体的温度、压力发生周期性变化，从而导致围岩中产生热应力，进而危及储气库注采过程中的安全运行。基于变质量热力学理论，推导出了注采过程中变注采速率的条件下腔内气体温度、压力随时间变化的微分方程，并结合已有的研究实例进行验证。基于单个腔体热固耦合模型，分别研究了注采气过程中，热效应、注采速率以及盐岩导热系数对腔体稳定性的影响。对于注气过程，热效应的存在、注气速率的增加以及盐岩导热系数的增大有助于避免围岩中发生拉伸损伤，维持腔体的稳定性；而对于采气过程，热效应的存在、采气速率的增加以及盐岩导热系数的增大会加剧围岩中的拉伸损伤，不利于腔体的稳定性。

Abstract:

Changes in the injection and production cycle of the underground gas storage with salt caves will cause periodic changes in the temperature and pressure of gas in the cavity, which will cause thermal stress in the surrounding rocks, endangering the safe operation during injection and productionin gas storage. Based on the theory of variable mass thermodynamics, the paper derives the differential equations of the gas temperature and pressure in the cavity changing with timeat avariable injection-production ratio, which are further verified by the existing research examples. Based on the thermal-solid coupling model of single cavity, a study is performed on the impacts of thermal effect, injection-production ratio, and thermal conductivity of salt rock on cavity stability during gas injection and production, respectively. For the process of gas injection, the thermal effect, and an increase in the gas injection rate and the thermal conductivity of salt rock help to avoid tensile damage in surrounding rocks and maintain the stability of the cavity. For the process of gas production, the thermal effect, and an increase in the gas injection rate and the thermal conductivity of salt rock will aggravate tensile damage in surrounding rocks, which is not conducive to cavitystability.

Key words: gas storage with salt caves, gas injection and production, thermal stress, cavity stability, numerical simulation
