Researchers have designed many kinds of hole cleaning tools to improve hole cleaning condition in the complex 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 tangential direction and axial direction are obtained by solving the model. The results show that blade helical angle as a controlling 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.

"My experiences in publishing a paper with Bentham Open is good. I must say that the speed of publication in The Open Petroleum Engineering Journal is very fast. It takes only two month for the pioneer reviewing process. The delay was caused by me. And what’s more, the publisher’s office is quite helpful. I guess they are dealing with thousands emails every week, but they process my request in a very short period of time."
