摘要
大位移井下套管作业在钻井作业过程中至关重要，作业质量的好坏直接影响到原油产量和油井寿命。国内油田发生的套管质量问题相当严重，由于套管损坏而造成油井报废累计已在数千口井以上，其中30％～50％是由于下套管作业操作不当造成的。详细介绍了大位移井下套管作业需要考虑的因素、下套管的方法、专用工具及发展方向。
Casing running of extend reach wells operations is very vital in the process of drilling operations, the quality of operations directly impacts on the quality of the crude oil production and life. Serious casing quality problems exist in domestic oilfield. And the casing damage caused by abandoned oil wells has accumulated over thousands of wells, of which 30 %- 50 % is due to the casing operations caused by improper operations. Therefore, casing running was an important issue. Factors of casing, methods of casing running and specific tool of casing running describes in detail in this paper.
