Asphaltene deposition is a long-standing problem that threatens the uninterrupted production of crude oil. Unlike other flow assurance problems, downhole asphaltene deposition is not well-understood partly as a result of the complexity and diversity of the asphaltene chemical structure. Continuous downhole asphaltene inhibitor injection is one of the preventive strategies used to mitigate the asphaltene deposition problem. Such chemicals that are injected in low dosage are screened in the laboratory before field implementation. Over the last 20 years, various asphaltene testing methods have been proposed for product selection and research and development. Still, the lack of lab to field correlation remains a challenge for the operators, service providers, and chemical companies. Therefore, the search for robust, rapid, and reproducible lab screening methods for asphaltene inhibitors is ongoing. This review summarizes lab evaluation techniques adopted by different researchers, their governing principles, and the pros and cons. It may serve as a guide for adopting appropriate strategies and pursuing further investigations on the lessons learned. The hope is that, with a more in-depth understanding of the current methodologies, a better workflow can be designed to select the proper asphaltene control products for field implementation.

审查当前选择沥青质抑制剂的实验室方法

沥青质沉积是一个长期存在的问题,它威胁着原油的不间断生产。与其他流动保证问题不同,部分由于沥青质化学结构的复杂性和多样性,并未很好地理解井下沥青质的沉积。连续井下沥青质抑制剂注入是用于减轻沥青质沉积问题的预防策略之一。在现场实施之前,在实验室中筛选低剂量注射的此类化学药品。在过去的20年中,已经提出了各种沥青质测试方法用于产品选择和研发。尽管如此,缺乏实验室到现场的关联仍然是运营商,服务提供商和化工公司的挑战。因此,寻求强大,快速,沥青质抑制剂的可重复实验室筛选方法正在进行中。这篇综述总结了不同研究人员采用的实验室评估技术,其管理原则以及利弊。它可以作为采用适当策略和对吸取的教训进行进一步调查的指南。希望是,在对当前方法有更深入的了解之后,可以设计出更好的工作流程来选择合适的沥青质控制产品用于现场实施。
