Efficiency of percussive drilling of rock with a bent drill rod
International Journal of Impact Engineering, 1994Summary Wave propagation and efficiency in percussive rock drilling with a bent rod is studied theoretically using a combined approach of FFT and matrix method. The bent drill rod is represented by straight uniform elements. The extensional and flexural stress waves in the drill rod are described by the one-dimensional wave equation and by Euler ...

Controlling efficiency of laser drilling
2014 9th International Microsystems, Packaging, Assembly and Circuits Technology Conference (IMPACT), 2014This study theoretically identifies the conditions for the keyhole collapse during drilling with a high intensity laser beam. Laser drilling is widely used in components, packaging and manufacturing technologies [1,2]. The approach adapted is to probe the quasi-steady, one-dimensional supersonic flow behavior of the two-phase, vapor-liquid dispersion ...

A Real Time Geomechanics Drilling Mud Window to Enhance Drilling Efficiency
SPE Conference at Oman Petroleum & Energy Show, 2022Abstract Enhancing the efficiency in drilling operations can lead to significant reduction in the overall costs of wells construction. Efficiency is generally achieved by maximizing drilling rate of penetration (ROP) while minimizing non-productive time (NPT) such as loss of circulation, well control and stuck pipe incidents.

Evaluation of a Drill Bit Button Arrangement for Enhanced Drilling Efficiency
Transactions of the Korean Society of Mechanical Engineers A, 2015The drill bit, which directly transmits percussive forces and torque to the rock, is the core part of a rock drilling machine. For effective drilling, the button arrangement of a drill bit should be optimized because it is the most important design factor in determining drilling efficiency.
