With the increase of the drilling directional well,horizontal well,extended reach well and multilateral well,at the high angle deviated hole,the axial force transfer becomes a problem.To reduce friction and transfer axial force continuously,the latest friction-reduce technology is the hydropulse axial-oscillation drilling technology,for this reason model SLZDQ172 axial-oscillation reduce friction tool was developed.The overall construction design and technical characteristic is introduced,how to design and manufacture the key components,including reasonably match and optimize the basic structure parameter of the power motor,simulation the flow area of the valve, the surface treatment and the computer aid design analysis of the spine mandrel,and the calcula-tion of the disc spring's pattern design.The lab and field test show that the tool is reliable and can improve weight transfer,reduce friction,and higher penetration rate.
