南海某无人平台外输泵工艺设计研究

Research on Process Design of Export Pumps on an Unmanned Platform in the South China Sea

海上无人平台在国内的各大海域日益增多,降低了海上设备的操维成本和人力成本,但是无人平台的安全可靠性要求较高.无人平台的油气生产工艺流程多为简易化,原油自油井开采出来后,不经过处理直接进入外输管道.南海某无人平台较为特殊,需要设置外输泵进行增压方可满足生产要求.此文通过设计研究和方案比选,首次在海洋平台上,创新性地采用柴油置换备用泵中的原油,并增设远程启动信号,当运行的外输泵故障后,操作人员可在其他平台或者终端远程启动备用外输泵,进而保证无人平台的正常生产和安全生产.

The number of offshore unmanned platforms is increasing in various sea areas in China, which reduces the operation and maintenance costs and labor costs of offshore equipment, but the safety and reliability of unmanned offshore platforms are required to be more stringent. The oil and gas production processes of unmanned platforms are mostly simplified, and after being extracted from oil wells, the crude oil directly enters the export pipeline without treatment. An unmanned platform in the South China Sea is quite special, and it is necessary to set up export pumps for boosting to meet the production requirements. In this paper, through design research and scheme comparison, for the first time on an offshore platform, diesel is innovatively used to replace crude oil in the standby pump, and a remote start signal is added. When the running export pump is breakdown, the operator can remotely start the standby export pump on other platforms or terminals to ensure the normal and safe production of the unmanned platform.
