FIELD: oil and gas production.
SUBSTANCE: system consists of drilling pipe connected to drill tool and of user control unit with data input device transferred into position within range of input signal and transmitting control signal proportional to position of device of data input within range of input signal. Further, the system consists of pump with range of output for transfer of a drill pipe at various levels of efficiency within the range of efficiency on base of a control signal, of controller connected to the user control unit and a pump and executing commands of programme stored in memory and facilitating performance of drilling operations at the first control setting, when range of pump output corresponds to the range of input of data of user control unit and changes of pump output are proportional to changes of position of the device for data input within the range of an input signal. The system includes performing drilling operations at the second setting of control, when range of pump output is restricted with output limit and changes of pump output are proportional to changes of position of the device for data input within the range of an input signal.
EFFECT: adjustment of control units for optimisation of working range of control units; control functions with low value at output proportional to full scale control over data input.
