Sprial glider centralizer

  • Glider Centralizer

  • Glider Centralizer
Presentation
Spiral centralizer has a smooth angle between spiral righting slip and axis, is superior than conventional straight edge style: Firstly, when down into the hole and meet irregular borehole diameter there will be lateral component created on spiral centralizer by the wall of  hole which can reduce the resistance to impact; Secondly, There will be Swirl flow out of the centralizer when cement slurry through the spiral sheet, get smooth, washed wall virtual mud cake, Whirl flow length is 7-9m, the best distance is 3-4m near the centralizer nearby, which can improve the displacement efficiency of cement slurry, which is very beneficial for improving cementing quality.
