Abstract:

To analyze the effect of directional nozzle layout to flow field at the bottom hole, CAD software in conjunction with Gambit is used to design PDC drill bit models with directional nozzles. The Fluent flow modelling was then used to perform flow simulations at the bottom hole. The research results show that the directional nozzle layout logically has maximized the ability to clean the bottom hole and minimize the formation of drill mud on PDC bit that ultimately to improve the efficiency of the drilling.
