Diamond drilling is one of the promising and versatile methods of well drilling, which makes it possible to achieve high drilling speeds at great depths of work. At the same time, an expensive diamond tool needs to save a resource. The developed method for managing diamond drilling based on a comprehensive analysis of criteria using the method of a full factorial experiment is effective if it is implemented in real time. Thus, the problem of developing an automated control system for the diamond drilling mode, which makes it possible to save the resource of the tool while ensuring high rates of mechanical drilling speed and minimal power consumption, is topical. This approach will improve the technical and economic results of diamond drilling. The aim of the work is to develop a reliable interactive system of ground sensors and a computer complex that allows implementing automated control of diamond drilling based on a comprehensive analysis of criteria that fully characterize complex drilling and operate in real time. Objects: diamond drilling, interactive systems, devices and sensors of the latest generation. Methods: analytical research, computer simulation, full factorial experiment. Results. The paper introduces the system of sensors and computing unit, consisting of computers and software, capable of collecting and processing information in detail, which makes it possible to give a full assessment of the work of the tool at the bottomhole. The authors describe the scheme of interaction of devices for automation of diamond drilling. The paper introduces the detailed description of the software operation from the sensor signal to the display of the results on the display screen and the characteristic of the result of the application of an automated control system for diamond drilling.
