摘要： 水下采油树系统正确选型对降低深水油气开发项目的综合成本至关重要。在充分分析调研的基础之上,归纳出一套深水水下采油树系统的选型方法:总结水下采油树、油管挂和树帽的结构形式特点及其适用范围,并分析井口连接器、水下阀门、水下监控设备等关键部件的选型考虑因素和配置要求,给出材料等级、压力等级、温度等级、产品规范等级、性能要求等级等关键工作条件参数的确定方法,并总结出水下生产控制系统和安装及修井控制系统的适用范围。

Abstract: Correct selection of subsea Christmas tree system is essential for reducing the cost of deepwater oil and gas development project. Based on extensive investigation and review, we systematically summarize the practical selection method for subsea Christmas tree system. Firstly, the characteristics of subsea Christmas tree, tubing hanger and tree cap are summarized. Secondly, the key selection issues and configuration requirements of tree wellhead connector, subsea valves and subsea monitoring and surveillance instruments are analyzed. Thirdly, the decision methods of material classes, pressure ratings, temperature classifications, product specification levels and performance requirement levels are given. Finally, the application scope of subsea production control systems and installation and workover control systems is described.
