Ultrasonic oil production technique for enhanced oil recovery (EOR) attracts more attention due to its high adaptability, simple operation, low cost and zero pollution to the oil reservoir. In this paper, recent new downhole tools used for enhanced oil recovery developed in China are summarized. Furthermore, research advance on some key problems that affect the widespread application of ultrasonic oil production technique in China are also summarized in view of what are the primary factors that influence crude oil paraffin inhibition and viscosity reduction, whether ultrasonic excitation is better than chemical agent for any plugs removal and whether ultrasound-chemical combination plug removal technology has the best plugs removal effect. The purpose of this paper is to provide reference for the broad application of ultrasonic oil production for enhance oil recovery.
用于提高采收率的超声波采油技术因其对油藏的高适应性、操作简单、成本低且无污染而备受关注。本文总结了中国近期开发的用于提高采收率的新型井下工具。此外，还从影响原油降凝降黏的主要因素、在解堵方面超声激发是否优于化学剂以及超声 - 化学联合解堵技术是否具有最佳解堵效果等方面，总结了影响超声波采油技术在中国广泛应用的一些关键问题的研究进展。本文旨在为超声波采油提高采收率的广泛应用提供参考。
