荣成海流能电站海上钻探技术研究

Study on Offshore Drilling Technologies of Ocean Current Power Plant in Rongcheng City

摘要:

海流能电站一般地处水深、流速大、水文条件较为复杂的海域。结合荣成海流能电站工程地质钻探的实践经验，论述了海洋工程的海上钻探工艺，包括钻探平台、钻探设备的选择及安装方法，综合阐述了海上钻探中船泊定位、套管安装、高程测量、钻探护壁、取芯等技术难题。对复杂海域条件下工程地质钻探施工的技术与方法进行分析，总结出了一套经济、适用、简便与安全的海域工程地质钻探方法和技术措施。

Abstract:

Ocean current power plant is generally constructed in the regions with deep water, high current rate and complex hydrological condition. Based on practical experiences of Rongcheng current power plant engineering drilling, offshore drilling technology has been introduced in this paper, including drilling platform, drilling equipment selection and drilling equipment installation. The technique problems, such as drilling platform positioning, tubular installing, height measurement and drilling core have been discussed in detail. On the basis of analyzing engineering drilling technologies and methods under complex sea region conditions, a set of economical, applicable, convenient and safe methods have been summarized and analyzed．
