采用水下压缩机增压技术，能够有效降低水下采油树井口压力，从而增加目标气田的产量，达到更好的经济效益。因此，水下压缩机增压技术近年来也越来越受到国内外石油公司的重视和青睐。本文针对水下压缩机的发展情况进行了研究，并结合南海某项目对水下压缩机的技术路线和适应性进行了对比分析，以期为未来水下压缩机增压项目选择合适的技术路线，提供借鉴。

The wellhead pressure of the subsea trees could be reduced dramatically by using subsea compressor technology, thereby increasing the production of the target gas field and achieving better economic benefits. The subsea compressor boosting technology has been increasingly valued and favored by domestic and foreign oil companies in recent years. This paper study on the development of the subsea compressor boosting technology and compare the technology roadmap of different subsea compressor to determine better solution for projects in Nanhai Sea in order to provide reference for future potential subsea compressor boosting project.
