水下管汇是水下油气田开发的核心装备，具有汇集、调节和保障水下油气生产等功能。根据不同油气田开发的需求，可以设计配置不同的结构和功能。本文以南海某深水油田水下管汇为例，对管汇基础的选型、关键技术和管汇模块的功能选型、新技术应用进行了分析、研究、总结，为我国水下管汇技术及关键设备研发提供借鉴和经验。

Subsea manifold is the core facility for subsea oil and gas fields development， is capable of gothering， tegulating， and ensurity underwater oil and gas production. It can be designed with different struture and function according the specific requirement of the oil and gas field. Base on the subsea manifold engineering experience in the South China Sea deepwater oil field， performing foundation type， key technology， manifold function module type and new technology application are analysised and researched. This study offers reference and experience for domestic subsea manifold technology and key equipment development.
