Abstract: To meet the requirement of complex reservoir drilling and completion on special completion string and tools, the Engineering Technology Research Institute of CNPC Bohai Drilling Engineering Co., Ltd. developed the full hole series liner hanger and systematic completion tools after years of efforts. The new equipment is characterized by advanced and rational design, high load carrying capacity, reliable and stable performance, simple operation in the field, and high success rate of pump pressure. Successful construction could easily be achieved using this tool. It could also meet the demand of liner cementing of various conventional wells, complex wells, and special wells. This paper mainly introduced the structure principle, technical parameters, and characteristics of the liner hanger, and gave a brief introduction to its field application.

Key words: cementing and completion, full size, liner, hanger
