摘　　要：海底多相分离技术是海洋油气开发中海底处理技术的核心,也是水下生产系统的重要组成部分。世界知名石油公司近年来非常重视水下紧凑型多相分离技术,研制开发了多种新型水下紧凑型多相分离技术和设备。介绍了海底立式沉箱类分离器、立式容器类分离器、卧式单根盘管式分离器、立式多管分离器等的结构和工作原理,并介绍了研发历程和相应的工程案例进展。部分侧重于进行油井产出液气-液分离用的技术方案打破了多相分离器设计的传统思维模式,为国内相关人员自主研发紧凑型多相分离技术提供了参考指导。The seafloor multistage separation technology is the key to the subsea oil and gas processing technology in offshore pe-troleum development as well as an important part of underwater production system. Distinguished international petroleum companies have attached great importance to the underwater compact multistage separation technology in recent years, developing some new underwater compact multistage separation technologies and equipments. The paper introduces the structure and operating principle of seabed vertical caisson separator, vertical vessel separator, horizontal single coil pipe separator and vertical multi-pipe separator. The history of devel-opment and the corresponding progress of engineering cases are also introduced. Part of the paper tocuses on the technological scheme for gas-liquid separation of produced fluid of oil well, which breaks the traditional thinking pattern in umltiphase separator design and provides the referenee for domestic researchers in independent development of the compact muhiphase separation technology.
