摘要： 钢悬链线立管适合于深水油气开发，国内工程应用需求与日俱增。国内某深水气田开发设计，存在深水钢悬链线立管应用方案。针对国内某深水气田，进行深水钢悬链立管回接方案研究，依据船舶资源，提出三种回接作业方案，以其中一种方案为例简要给出作业程序，并对三种回接方案进行可行性、作业风险和经济性对比分析。研究对深水钢悬链线立管回接作业具有工程应用参考价值。

Abstract: SCR is a favorable solution to deep water oil and gas development. Actual engineering requirement on SCR in domestic application is increasingly growing. One domestic deepwater development project in recent years has the plan of SCR application. Aimed at this project, three SCR tie-back and installation plans were put forward based on different operation vessels. As an example, operation procedure of one of the plans was presented generally. Applicability and economy analysis and comparisons among these three plans were also perfomed. This study has reference and guidance value on deep water SCR tie-back and installation in engineering application.
