深水油田立式水下采油树安装操控作业

Installation and control of underwater vertical christmas tree in deepwater oil field

立式水下采油树安装操控作业是当今国际深海油田钻完井的核心技术之一。根据在A深海油田的实际作业管理经验,介绍了立式水下采油树水下控制系统构成及工作流程,详细描述了立式水下采油树的安装及解脱作业过程,并提出一种解决应急解脱作业过程钢圈密封失效的方法,对从事深水钻完井作业工程设计人员和作业管理人员具有一定的指导意义。

The installation and control of vertical underwater Christmas tree is one of the present international deep-sea oil field drilling and completion core technology. Based on the management experience of practical work in a deepwater oilfield, makes an introduction on structure of system and technological process of the control system for vertical underwater Christmas tree. In addition, the paper describes in detail the course of the installation and extrication for vertical underwater Christmas tree, finally put forward the solutions to steel ring Seal Failure in operation process of the emergency release mechanism. The research on technology for vertical underwater Christmas tree has directive significance to the engineering designers and operating managers.
