顶驱下套管作业装备配套及工艺初探

摘要

The application of Top Drive Casing Running System(CRS) to run casing has many advantages, such as high work efficiency, high quality connection makeup, with increased safety and low labor intensity, which can decrease or avoid the emergence of downhole accident, hence reduce the drilling cost. The precondition of successful casing running to the intended depth by CRS successfully is an appropriate equipment selection. In order to guide the future engineering practice,field experiences are summarized, what kind of equipment, how to equip them(that is the technique process) are discussed in the paper.%利用顶驱下套管装置进行下套管作业具有作业效率高、套管上扣质量高、现场作业安全度高、劳动强度低等优点,可降低或避免井下事故的发生,降低钻井综合成本.配备相应的装备是保证套管顺利下入预定深度的前提.根据现场试验结果,就配套装备及其工艺流程进行了初步探索和讨论,对工程实际作业具有指导意义.
