Although new energy has been widely used in our lives, oil is still one of the main energy sources in the world. After the application of traditional oil recovery methods, there are still a large number of oil layers that have not been exploited, and there is still a need to further increase oil recovery to meet the urgent need for oil in the world economic development. Chemically enhanced oil recovery (CEOR) is considered to be a kind of effective enhanced oil recovery technology, which has achieved good results in the field, but these technologies cannot simultaneously effectively improve oil sweep efficiency, oil washing efficiency, good injectability, and reservoir environment adaptability. Viscoelastic surfactants (VES) have unique micelle structure and aggregation behavior, high efficiency in reducing the interfacial tension of oil and water, and the most important and unique viscoelasticity, etc., which has attracted the attention of academics and field experts and introduced into the technical research of enhanced oil recovery. In this paper, the mechanism and research status of viscoelastic surfactant flooding are discussed in detail and focused, and the results of viscoelastic surfactant flooding experiments under different conditions are summarized. Finally, the problems to be solved by viscoelastic surfactant flooding are introduced, and the countermeasures to solve the problems are put forward. This overview presents extensive information about viscoelastic surfactant flooding used for EOR, and is intended to help researchers and professionals in this field understand the current situation.

粘弹性表面活性剂提高采收率的研究进展

尽管新能源已广泛应用于我们的生活中,但石油仍然是世界上的主要能源之一。在应用了传统的采油方法之后,仍然有大量未开发的油层,因此仍然需要进一步提高采油率,以满足世界经济发展对石油的迫切需求。化学强化采油(CEOR)被认为是一种有效的强化采油技术,在现场取得了良好的效果,但是这些技术不能同时有效地提高扫油效率,洗油效率,良好的注入性和储层环境。适应性。粘弹性表面活性剂(VES)具有独特的胶束结构和聚集行为,可有效降低油和水的界面张力,以及最重要和独特的粘弹性等,引起了学者和现场专家的关注,并被引入到提高采油率的技术研究中。本文详细讨论了粘弹性表面活性剂驱的机理和研究现状,总结了不同条件下粘弹性表面活性剂驱的实验结果。最后,介绍了粘弹性表面活性剂驱替要解决的问题,并提出了解决问题的对策。本概述提供了有关用于EOR的粘弹性表面活性剂驱油的广泛信息,旨在帮助该领域的研究人员和专业人员了解当前的情况。它引起了学者和现场专家的关注,并被引入到提高采油率的技术研究中。本文详细讨论了粘弹性表面活性剂驱的机理和研究现状,总结了不同条件下粘弹性表面活性剂驱的实验结果。最后,介绍了粘弹性表面活性剂驱替要解决的问题,并提出了解决问题的对策。本概述提供了有关用于EOR的粘弹性表面活性剂驱油的广泛信息,旨在帮助该领域的研究人员和专业人员了解当前的情况。它引起了学者和现场专家的关注,并被引入到提高采油率的技术研究中。本文详细讨论了粘弹性表面活性剂驱的机理和研究现状,总结了不同条件下粘弹性表面活性剂驱的实验结果。最后,介绍了粘弹性表面活性剂驱替要解决的问题,并提出了解决问题的对策。本概述提供了有关用于EOR的粘弹性表面活性剂驱油的广泛信息,旨在帮助该领域的研究人员和专业人员了解当前的情况。详细讨论了粘弹性表面活性剂驱的机理和研究现状,总结了不同条件下粘弹性表面活性剂驱的实验结果。最后,介绍了粘弹性表面活性剂驱替要解决的问题,并提出了解决问题的对策。本概述提供了有关用于EOR的粘弹性表面活性剂驱油的广泛信息,旨在帮助该领域的研究人员和专业人员了解当前的情况。详细讨论了粘弹性表面活性剂驱的机理和研究现状,总结了不同条件下粘弹性表面活性剂驱的实验结果。最后,介绍了粘弹性表面活性剂驱替要解决的问题,并提出了解决问题的对策。本概述提供了有关用于EOR的粘弹性表面活性剂驱油的广泛信息,旨在帮助该领域的研究人员和专业人员了解当前的情况。并提出了解决问题的对策。本概述提供了有关用于EOR的粘弹性表面活性剂驱油的广泛信息,旨在帮助该领域的研究人员和专业人员了解当前的情况。并提出了解决问题的对策。本概述提供了有关用于EOR的粘弹性表面活性剂驱油的广泛信息,旨在帮助该领域的研究人员和专业人员了解当前的情况。
