The article considers application technology and operation peculiarities of downhole motors. Essential rules and requirements to the process control of downhole motor operation have been highlighted. On the basis of main and new principles it has been proposed to automate technological drilling process as per the basic circuit arrangement of the feed off control, taking into consideration a new elementary base and current achievements. Also the article includes stages of implementation technology, results of the first stage. On the research diagrams of the geotechnical study examples of interval drilling with and without electric powder brake have been considered. The drilling technology analysis with the electric powder brake has showed importance of operations renewal on a wide range of application of the feed off control.
