Abstract The purpose of this work is to analyze the prospects for efficiency increasing of high-tech wells construction using a drilling complex based on downhole permanent magnet motor. For the first time, the article provides information about new drilling complex. Considered technology could provide a breakthrough in drilling high-tech wells. This technology combines advantages of drill string with electric wire and an ideal downhole motor with a wide rotational speed range, regardless of the type and flow rate of circulating agent. The article provides a brief comparative analysis of electrodrilling implementation results "generation 70s", the composition of new electric drilling complex and its difference from the previous one are considered in details. Complex meets the requirements of high-tech wells construction and allows automating drilling process using ultra-high-speed bi-directional data transmission channel and quickly assessing the parameters of drilling regime and direction of drilling, characteristics of rocks, pressure and temperature distribution along the wellbore. Permanent magnet motor ensures optimum drilling parameters for rock destruction at the bottomhole, regardless of the well profile and the type of circulating agent, including managed pressured drilling. Effectiveness of accidents prevention and mitigation is increased. Authors propose to discuss the prospects of electrodrilling technology using downhole permanent magnet motor, which is currently at TRL-3 level, to assess and specify adopted concept of electrical drilling complex development.

This paper gives an introduction of the simulation of ultra-high-speed drilling on the copper of printed circuit board (PCB) by using finite element method (FEM). The cutting force, cutting torque and the distribution of cutting temperature are predicted. The value of cutting force is also be compared with the experimental value. The simulation results show that the experimental value of cutting force agrees well with the FEM value and the value of cutting torque is very small in the drilling process , in addition，the maximum temperature of copper comes up to 209 °C in center area and the temperature of copper chip evacuation from the spiral groove ranges from 135°C to 155 °C.

Drilling Conditions

A hybrid experimental-numerical methodology is applied to evaluate the unwanted stresses induced by hole-drilling in two 5000 and 7000 series aluminium alloys. The influence of the cutting speed of ultra-high speed drills powered by turbine systems by compressed air, which are commonly used in the hole-drilling equipments for residual stress measurements, is analyzed. The comparison of the effect of different drilling conditions on the drilled material using a quantitative approach is now possible. The applied methodology can play an important role on the improvement and optimization of the hole-drilling technique for residual stress measurements in particular and the drilling process in general.
