FIELD: oil and gas industry.
SUBSTANCE: group of inventions falls into the area of the oil and gas producing industry, in particular to the control systems in the well using the screw coal-face mechanisms. The system contains a mud drill collar, a sleeve of the stator, installed with a possibility to rotate in the mud drill collar, a rotor installed with a possibility to rotate in the sleeve of the stator, and the rotor's rotating respectively to the sleeve of the stator is correlated with the volume consumption of the fluid, passing between the rotor and the sleeve of the stator, and the rotor is fixed to prevent the planet motion so that its axis is fixed respectively to the mud drill collar during its rotating respectively to the mud drill collar.
EFFECT: document describes the principle of the work of the control system based on the screw coal-face mechanism.
