FIELD: oil and gas production.
SUBSTANCE: device contains pressure gauge receiving one or several pressure pulses and module of electronic instruments maintaining connection with pressure gauge. The module of electronic instruments determines command of pressure pulses to actuate the downhole tool. An engine is coupled with the module of electronic instruments. The engine is tied with a connecting mechanism converting rotating motions of the engine into a linear motion. Additionally the device is equipped with a valve system coupled with the connecting mechanism. The valve system actuates the downhole tool when the valve system is in an open phase.
EFFECT: increased accuracy of control of drive of downhole tools due to decreased power consumption for driven tool and due to generation of differential pressure with low pressure in atmospheric chamber and high pressure of well fluid.
