Abstract:
In
order to improve the efficiency of wellbore purification devices for hydraulic
machinery, a numerical calculation model for different types of cuttings bed
remover tools is established based on computational fluid dynamics theory.The numerical simulation calculation method is used to
study the influence of spiral channel shape and spiral blade structure
parameters on the effect of cuttings removal tool.The results show that the
cuttings bed removal tool with a double-segment spiral channel shape has better
performance.Properly
increasing the length of the second spiral channel while reducing the pitch of
the spiral blade can improve its performance.By gradually optimizing the design and optimizing
the relevant structural parameters, the purpose of improving the performance of
the cuttings bed removal tool is achieved,and a certain theoretical basis is provided for the
optimal design of the cuttings bed removal tool.
