“…Through multiple simulation analyses, it is possible to assess the stress conditions of the Variable Diameter Stabilizer in static and rotational states, understanding how different parameters influence its performance. Flow field analysis can also examine the impact of the Variable Diameter Stabilizer on drilling fluid flow, particularly the vortex region's influence on cuttings removal and drilling efficiency [ 4 , 5 ]. Presently, research on Variable Diameter Stabilizers primarily focuses on the following aspects:…”
