Research on the Bottom Hole Flow Field of PDC Bit

Hui ZHANG

Abstract


The three-dimension model of PDC bit was constructed in ANSYS software in order to obtain the physical model of the PDC bit’s flow field on bottom hole. 3D geometric model of PDC bit was created by ANSYS and meshed by GAMBIT, analyzed by FLUENT by setting boundary condition of velocity inlet and outflow. Finally, we get the flow field figure while the velocity is 232 m/s. The district where fluid speed is slow and there is reverse flow is small between borehole wall and the nozzle which is far from the center of bit. The district where fluid speed is slow and there is reverse flow is small between axes of bit and the nozzle which is close to the center of bit. If the nozzle velocity is different, the effect to clear and carry over cuttings will be more obvious. The speed of the nozzle which is close to the center of bit should be highest. The two nozzles adjacent to this nozzle should have higher speed.
