本文给出了两台多相混输泵现场试验的结果。一台泵装在墨西哥湾的一个近海平台上，与一口气举井串接；另一台泵用于加拿大阿尔伯塔省的陆上油田，与一口抽江机井串接。安装在近海平台上的多相泵的主要作用是通过降低井口回压来增加产量，其增产效果已远远超过期望值。该泵现己安装了单作用机械密封系统，解决了先前双作用机械密封系统的泄漏问题。两个油田的试验都提供了多相泵的性能数据和运行管理经验。 This paper gives the results of field tests on two multi-phase mixed pumps. One pump was installed on an offshore platform in the Gulf of Mexico, connected in series with a breath lift. The other pump was used in onshore oil fields in Alberta, Canada, in series with a pumping well. The main function of a multiphase pump installed on an offshore platform is to increase production by reducing back pressure at the wellhead, which has far exceeded the expected value. The pump now has a single-acting mechanical seal system installed that solves the leak problem of previous dual-acting mechanical seal systems. Both field trials provide multi-phase pump performance data and operational management experience.
