| description | The invention provides a walking-beam pumping unit balance adjusting method and device and relates to the technical field of walking-beam pumping units. The method includes the steps that all balance adjusting parameters of a walking-beam pumping unit are obtained and include the weight of each crank balance block, the number of the crank balance blocks, the initial positions of the crank balance blocks, the ground efficiency of the walking-beam pumping unit and polish rod stroke frequency of the walking-beam pumping unit; upstroke average power and downstroke average power of the walking-beam pumping unit are obtained through an active power tester connected with the walking-beam pumping unit; accordingly, a balance adjusting coefficient is determined; then the balance adjusting distance is determined; and a target position is determined according to the initial positions of the crank balance blocks and the balance adjusting distance, and the crank balance blocks are adjusted to the target position.
