自安装井口平台台风状态在线数据监测的研究

Study on On-line Data Monitoring of Self-elevating Wellhead Platform under Typhoon Condition

自安装式井口平台(WESU)作为海上边际油田的重要解决方案,已经在北部湾海域部署。其插装站立方式不同于传统导管架平台,虽然在设计参数中充分考虑了北部湾海域的天气情况,但仍然需要在台风状态下对平台关键位置参数进行数据监测。通过阐述北部湾海域某自安装井口平台在正常生产和台风状态下平台数据监测与回传的需要,提出了针对平台桩腿、导管架支撑、平台摇摆度、气象数据的监测与回传技术,能够为类似自升式平台的防台风措施提供参考。

As an important solution for offshore marginal oil fields,self-elevating wellhead platforms(wesu)have been deployed in the Beibu Gulf.The installation and standing modes of self-elevating wellhead platforms are different from the traditional jacket platform.Although the weather conditions in the Beibu Gulf are fully considered in the design parameters,it is still necessary to monitor the key position parameters of the platform under typhoon condition.This paper expounds the needs for data monitoring and return of a self-elevating wellhead platform in the Beibu Gulf sea area under normal production and typhoon conditions,and puts forward the monitoring and return technologies for platform pile legs,jacket support,platform swing and meteorological data,which can provide reference for typhoon prevention measures of similar to self-elevating platforms.
