Numerical Computation Studies and Hydrodynamic Analysis on the Cutting-Carrying and Lifting Capacity of Spiral Centralizer in Gas Drilling
For gas drilling, hole cleaning is a particularly critical problem. When the spiral centralizer is used in the down hole assembly of gas drilling, it will produce a powerful rotational flow which will be bond to have the influence of different level on the hole cleaning. For this matter, this paper...
