扫描声呐技术在近平台钻井船就位中的应用

Application of Scanning Sonar Technology for Drilling Ship in Place Nearby the Platform

近平台钻井船就位前,需对就位区域进行精细地貌调查,目前常规物探调查方法难以实现。通过对扫描声呐系统工作原理和特点进行研究,总结出了一整套应用于近平台钻井船精细地貌调查方法、解释程序和注意事项,有效解决了常规物探调查难以实现、精度低等难题。本文结合扫描声呐技术在近平台钻井船就位项目实际案例,展示了其高精度、高效性等技术特点及作业优势,为以后近平台钻井船就位区域地貌精细调查项目实施提供了指导与参考。

Before drilling ship in place nearby the platform,it is necessary to carry out a detailed geomorphological survey in the in-place area.By studying the working principle and characteristics of scanning sonar system,the methods,interpretative program and notes are proposed for carrying out detailed geomorphological survey by using scanning sonar technology for the purpose of drilling ship in place nearby the platform,which solves effectively the problem that can not be solved by the routine geophysical survey methods.It has been seen from a practical application case that the scanning sonar technology can provide high accuracy,high efficiency and advantage of operation for the detailed geomorphological survey in the in-place area.The methods proposed in the paper can provide guidance and reference for detailed and accurate geomorphological survey in the area where the drilling ships will be in place nearby the platform.
