Lower J55 steel-grade bushing whether can with the problem of, and the problem of non-study " casing can by maximum hole curvature ".
Xu Jinchao devises drilling pipe bending and turns to indoor experimental apparatus, which is used as simulation slideway using roller group,
16Mn seamless steel pipe provides pressure under drilling pipe as simulation drilling pipe, hand hydraulic pump.Passed through by vernier caliper measurement drilling pipe,
Retract change in size, pressure under gauge measurement drilling pipe, thus to realizing that it is preferred that curved different size drilling pipe carries out.But the reality
The building of experiment device slideway is cumbersome, and hole curvature changes difficult.
Chinese utility model patent ZL200720158882.X devises high angle hole drilling pipe bending deformation simulative test dress
It sets, simulates the stress bending deformation of high angle hole tubing string, by stress twisted rope, promote tubing string, detection tubing string handling capacity simulates well
The stress size and bending deformation of cylinder.The simulation test device is only suitable for simulating the handling capacity of upper lifting pipe post, but cannot simulate
Transfer the handling capacity of tubing string.
