Key words: sucker rod pump unit, hydraulic drive of sucker rod pump, balancing methods, inertial balance, area of application.
It is noted that for the operation of the failed oil wells and the newly commissioned ones it is needed cheap sucker-rod pump drives, allowing to refuse from the massive foundations and providing reduction of the servicing labor. These drives are hydraulic actuators with inertial balance. Element base of hydraulic drive, used in road and construction machinery, machine hydraulic drive, which is used in the proposed type of drive, as well as the common qualification level of oil field workers allow to go on to create a new type of hydraulic drive on a higher technology and engineering level.
