浅海海底管道内检测流程研究

Technological process of internal inspection for shallow water submarine pipelines

针对胜利浅海油田海底管道开展内检测工作中流程存在的问题,在分析了海底管道的工程设计、在役运行、检测现状的基础上,根据通用管道内检测要求建立了初步的内检测基本工作流程,结合海上平台工艺流程中没有收发球装置以及平台工作空间不足的实际情况,提出了工艺流程改造方案,优化了海底管道内检测流程,并进行了工程验证。

In view of the problems existing in the internal inspection process of submarine pipelines in Shengli shallow sea oilfield and based on the analysis of the present situation of engineering design,operation and inspection of submarine pipelines,the basic workflow of internal inspection was established according to the requirements of general pipeline internal inspection.Combined with the actual situation of no pig receiving and launching device in the technological process and insufficient work space of offshore platform,the technological process reformation scheme was put forward,the internal inspection process of submarine pipelines was optimized,and the engineering verification was carried out.
