基于光电复合缆的多参量实时监测海底基盘的探讨与实现
|
摘要
海洋钻探,尤其是水深达到一定深度的深海钻探,需要由坐落于海床面的海底基盘进行辅助。本文在调研的基础上,探讨了海底基盘的多种工作方案,并针对具体的需求,研发了一种基于光电复合缆的多参量实时监测海底基盘,并在传统的海底基盘仅提供钻杆夹持的基础上增加了可视化、井口气体监测等功能,还预留了海底弃钻剪钳和重返钻孔等功能接口。通过海上试验,研制的海底基盘从耐压、供电、通讯、图像采集等通用技术测试,到钻杆夹钳的夹持力、响应时间、井口溶解气体监测等特殊技术测试均达到了设计的技术要求。
Ocean drilling, especially in a deep depth, usually needs to be assisted by a seabed frame when conducting the drilling survey. On the basis of preliminary research, we discuss the advantages and disadvantages of different kinds of seabed frame, and propose a kind of multi-parameter real-time monitoring seabed frame based on photoelectric composite cable according to the specific needs. Besides the traditional function of clamping drill rod, the said seabed frame has additional functions such as visualization and wellhead gas monitoring, functional interfaces for undersea drill rods cutting machine and re-entry drilling have also been reserved. By conducting the offshore test, the results showed that the new developed seabed frame has met both the universal technical requirements(such as pressure resistance, power supply, communication, image acquisition) and special technical requirements of the design(such as clamping force, responding time, and monitoring of dissolved gas at the wellhead included).
