Abstract This article comprehensively reviews the potential application and effects of different moieties of ionic liquids (ILs) on shale stabilization processes. The shale swelling inhibitory mechanisms and dispersion properties of 22 ILs were discussed. The effect of IL's concentration, temperature, chain length, cations, anions and polymerization functionally are discussed. Also, the toxicity and biodegradability of ILs are briefly provided. This study highlighted that more positive groups and alkyl substituents, and shorter alkyl chains are helpful for high performances. Understanding different IL's anion/cation effects are highly required. The study provides guidelines to design ILs for shale stabilization.

离子液体在页岩稳定过程中的潜在应用概述

摘要 本文全面综述了不同部分离子液体（ILs）在页岩稳定过程中的潜在应用和影响。讨论了 22 种离子液体的页岩膨胀抑制机制和分散特性。讨论了离子液体的浓度、温度、链长、阳离子、阴离子和聚合功能的影响。此外，简要提供了 ILs 的毒性和生物降解性。该研究强调，更多的正基团和烷基取代基以及更短的烷基链有助于提高性能。非常需要了解不同 IL 的阴离子/阳离子效应。该研究为设计用于页岩稳定的 IL 提供了指导。
