The wettability of carbonate rocks is often oil-wet or mixed wet. A large fraction of oil is still remained in carbonate reservoirs, it is therefore of particular significance to implement effective methods to improve oil recovery from carbonate reservoirs. Altering wettability from oil-wet to more favorable water-wet has been proven successful to achieve this goal. Surfactants are widely investigated and served as wettability modifiers in this process. Yet a comprehensive review of altering wettability of carbonate reservoirs with surfactants is ignored in literature. This study begins with illustration of wettability evolution process in carbonate reservoirs. Techniques to evaluate wettability alteration extent or to reveal behind mechanisms are also presented. Several surfactant systems are analyzed in terms of their wettability alteration mechanisms, influential factors of performance, applicable conditions, and limitations. Mixture of different types of surfactants could obtain synergic effects, where applicable conditions are extended, and final performance is improved. Gemini surfactants have many desirable properties, which warrants further investigation for understanding their wettability alteration mechanisms and performance. At the end, this review discusses strategies related with surfactant cost, surfactant adsorption, and challenges at high temperature, high salinity reservoirs conditions. Also, some unclear issues are discussed.

表面活性剂在碳酸盐岩储层润湿性改变研究进展

碳酸盐岩的润湿性通常是油湿的或混合湿的。碳酸盐岩油藏中仍有很大一部分石油残留,因此实施有效的方法提高碳酸盐岩油藏的采收率具有特别重要的意义。将润湿性从油湿性改变为更有利的水湿性已被证明可以成功实现这一目标。表面活性剂被广泛研究并在该过程中用作润湿性改性剂。然而,文献中忽略了用表面活性剂改变碳酸盐岩储层润湿性的综合综述。本研究首先说明碳酸盐岩储层的润湿性演化过程。还介绍了评估润湿性改变程度或揭示背后机制的技术。分析了几种表面活性剂体系的润湿性改变机制、性能影响因素、适用条件和局限性。不同类型表面活性剂的混合可产生协同效应,在扩大适用条件的情况下,提高最终性能。Gemini 表面活性剂具有许多理想的特性,需要进一步研究以了解其润湿性改变机制和性能。最后,本综述讨论了与表面活性剂成本、表面活性剂吸附以及高温、高盐度储层条件下的挑战相关的策略。此外,还讨论了一些不清楚的问题。扩展适用条件并提高最终性能。Gemini 表面活性剂具有许多理想的特性,需要进一步研究以了解其润湿性改变机制和性能。最后,本综述讨论了与表面活性剂成本、表面活性剂吸附以及高温、高盐度储层条件下的挑战相关的策略。此外,还讨论了一些不清楚的问题。扩展适用条件并提高最终性能。Gemini 表面活性剂具有许多理想的特性,需要进一步研究以了解其润湿性改变机制和性能。最后,本综述讨论了与表面活性剂成本、表面活性剂吸附以及高温、高盐度储层条件下的挑战相关的策略。此外,还讨论了一些不清楚的问题。
