锚固斜孔长螺旋钻进技术研究

Drilling Technology for Oblique Bore by Long Spire

分析螺旋叶片的结构参数可为设计提供依据。根据斜孔钻进土屑运移情况 ,建立力学模型并确定钻进合理工艺参数。

Analysing the parameters of spire blade can provide the basis for designing. The model of mechanics and conclude the reasonable parameters of drilling was built based on the drilling of oblique bore. The consideration for designing of spire driller and the improvable measure for drilling was introduced.
