紧凑型整体锻造水下阀门组技术方案研究

Research on the Technology of Compact Forged Subsea Valve Block(CFSVB)

本文研究了紧凑型整体锻造水下阀门组的技术方案。首先,以4口井海洋油气田开发项目为例,比较分析了传统丛式水下管汇、紧凑型整体锻造水下阀门组管汇的设计、加工、安装作业等方面,由此提炼总结了紧凑型整体锻造水下阀门组的关键设计技术;依托实际工程项目进一步阐述了紧凑型整体锻造水下阀门组的优势,并给出了未来应用方向预测。本文为深入研究以紧凑型整体锻造水下阀门组为基础的水下基盘开发方式,以及水下整装油气田开发思路提供了新思考。

This paper is devoted to the technology study regarding Compact Forged Subsea Valve Block(CFSVB).Firstly,through an example of four-well offshore oil/gas field development project,a comparison between traditional cluster subsea manifold and CFSVB manifold is conducted from the aspects of design,manufacture,installation,and subsea operation,based on which the key design technology and design of CFSVB is summarized.In addition,the advantage of CFSVB is further illuminated with an example of offshore oil field development project,and the application direction area of CFSVB is predicted.The present research provides novel concept towards deeper studies of CFSVB-based subsea template,as well as the development strategy of subsea complete-structure oil and gas field.
