摘要
海底基盘是海洋钻井和取样的重要设备之一,用于钻井作业井口定位、钻具导向及夹持稳定、井口监视,并可根据需要搭载静力触探、取心、测井等其他附属仪器装置。海底基盘是集机、液、光、电一体化的设备,由机械结构、液压系统和控制系统组成。本文针对海底基盘工作需求,提出了一套具有钻杆夹持、视频寻址、图像采集、井口信息监测等功能的海底基盘控制系统方案,控制系统作为设备核心,其由配电系统、光电测控系统和水下液压动力站等组成。
The seafloor template is one of the important equipment for offshore drilling and sampling. It is used for wellhead positioning, drilling tool guiding and clamp stabilization, and wellhead monitoring. It can also be equipped with other tools for cone penetration test, coring, logging, etc. The seafloor template is a device that integrates machinery, hydraulic system, optical fiber communication, and electrical automation. It consists of mechanical structure, hydraulic system and control system. With the working requirements of the seafloor template in mind, this paper proposes a seafloor template control system including drill pipe clamping, video addressing, image acquisition, wellhead information monitoring, etc. The control system, as the core equipment, includes the power distribution system, the photoelectric measurement and control system, and the underwater hydraulic power station.
