EXPERIENCE OF DRILLING OF HIDDEN-DIRECTED AND HORIZONTAL BOREHOLES

Abstract

The paper discusses the advantages, disadvantages and prospects of using electric drilling. Drilling using adjustable electric drills (DC motors) combines the benefits of rotary drilling, turbine drilling, and drilling with hydraulic downhole motors. It provides the ability to control the frequency of rotation of the bit, regardless of the parameters and type of agent for the removal of cuttings, significantly expands the range of drill bits and makes it possible to obtain a stable downhole signal. The first steps were taken by Ukrainian oil workers and scientists - a prototype of a DC electric drill was developed
