The aim of this paper is to provide a comprehensive review of potential changes in the chemical and mineralogical environments of saline aquifers due to CO2 injection under in situ conditions, and the influence of these changes on the hydromechanical behavior of reservoir rock. The effect of aquifer characteristics, such as pH and ionic composition, on the hydromechanical properties of reservoir rock are also considered. However, the CO2 injection-induced hydromechanical properties of saline aquifers vary significantly with the properties of the aquifer and the injecting gas, which causes this to be complex, and to date, insufficient studies have been undertaken. Furthermore, this study identifies the chemically corrosive nature of different host fluids, which leads to decreased rock strength and increased crack propagation velocity during CO2 sequestration.

深盐水层中二氧化碳封存的化学和矿物学问题综述。

本文的目的是全面回顾由于在原位条件下注入 CO2 导致咸水层化学和矿物环境的潜在变化，以及这些变化对储层岩石流体力学行为的影响。含水层特征（如 pH 值和离子组成）对储集岩流体力学性质的影响也被考虑在内。然而，二氧化碳注入引起的咸水层的流体力学特性随含水层和注入气体的特性而显着变化，这导致其变得复杂，迄今为止，尚未进行足够的研究。此外，这项研究确定了不同宿主流体的化学腐蚀性，
