METHOD OF CONTROLLING MOVEMENT OF LEVER DEVICE FOR DELIVERING INSTRUMENTS AND EQUIPMENT TO HORIZONTAL AND PENCHANT SECTIONS OF CASED AND UNCASED WELLS Russian patent published in 2020 - IPC E21B23/14 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry. Disclosed is a method of controlling movement of a lever device for delivering instruments and equipment to horizontal and highly inclined sections of cased and uncased wells. In order to achieve the declared technical result, the traction links of the device are equipped with sensors and electronic units to provide control of conditions and rapid response of the device to change of movement-preventing factors. System is also equipped with low-speed telecommunication systems for communication via a geophysical cable from an on-board computer of a ground-based logging system, which is high-speed for real-time control of traction link motors and readings of sensors. Movement of traction links and pressing of the fixing assembly is performed by alternate actuation of electric motors at the command of the electronic unit controller. At the same time with the help of the electronic unit controller the traction links pressing is controlled with the help of sensors and movement control determined by control intervals of the beginning and the end of movement, measured by the number of electric motors revolutions.

EFFECT: technical result consists in uniform non-stop movement of lever device for delivery of instruments and equipment to horizontal and highly inclined sections of cased and uncased wells with provision of accident-free passage of well and increase of speed of movement.
