摘要
2018年,勘探四号半潜式钻井平台圆满完成韩国大宇弃置项目。在Ф244.5 mm套管切割回收作业中,采用了新的Ф244.5mm套管切割回收工艺,将切割和打捞两项作业结合,仅使用一趟钻具组合就完成套管的切割和回收作业,减少了组合BHA和起下钻次数,简化了作业流程,大大提高了作业的效率和可靠性.
In 2018,KAN TAN IV semi-submersible drilling platform successfully completed the DAEWOO abandoned well in South Korea.In Ф244.5 mm casing cutting and fishing operation,the cutting and fishing operations were combined in the abandonment program,and the casing cutting and fishing was completed with a single run of string,which reduced the make-up BHA and trips.This simplified the operation process,and improved the operation efficiency and reliability.
