摘　　要：扩眼刀翼是扩眼器实现扩大井径关键的核心结构之一,要求刀翼结构布局合理、应用高效。扩眼刀翼防泥包是扩眼器应用高效的关键点之一,而优化喷口形状及倾角可以有效解决扩眼刀翼泥包问题。本文在特定的工况对扩眼刀翼喷口进行了倾角的选择,并分析了喷口角度、排量、粘度及泥浆密度对扩眼刀翼防泥包的影响。The reamer blade is one of the core structures critical for enlarging the wellbore diameter,which requires a reasonable layout and efficient application.Preventing balling on the reamer blades is a key to the efficient application of reamers,and optimizing the nozzle shape and inclination angle can effectively address the issue of balling on reamer blades.This paper selects the inclination angle of the nozzle on the reamer blades under specific working conditions and analyzes the impact of the nozzle angle,flow rate,viscosity,and mud density on the prevention of balling on reamer blades.
