查询词典 perpendicular

Correlation of drillability anisotropy index of the roller cone bit and PDC bit, the difference between drillability of the roller cone bit in perpendicular and horizontal directions of the bedding plane with the P-wave velocity anisotropy coefficient are studied respectively by means of mathematical statistics. A mathematical model is established for predicting drillability anisotropy index by using P-wave velocity anisotropy coefficient.
