Abstract
Researchers have designed many kinds of hole cleaning tools to improve hole cleaning condition in the com- plex structural wells. In this paper a mathematical model was built to analyzing the cutting particles movement on the helical blades of hole cleaning tool. The relationships between blade helical angles and cuttings transport velocity in tan- gential direction and axial direction are obtained by solving the model. The results show that blade helical angle as a con- trolling variable has a significant impact on application effect of the spiral hole cleaning tool; tangential cuttings velocity increases and axial cuttings velocity decreases with the increase in the helical angle and adjusting the helical angle can reach the required cuttings velocity.
