The invention relates to an adjustment method for operation balance of a rod-pumped well and belongs to the technical field of oil production of oil fields. The adjustment method aims at achieving convenient and practical measurement of balance adjustment of the rod-pumped well on site. The adjustment method is characterized in that an active power average value and an upstroke and downstroke net torque superposition value P<up and down> are obtained; an annulus working fluid level HY is obtained according to P<up and down>; according to an upstroke active power average value <up> and a downstroke active power average value <down>, whether balance blocks need to be moved and adjusted and whether the moving directions of the balance blocks need to be adjusted are judged; if adjustment is needed, the adjustment moving amount of the balance blocks of a pumping unit is determined, and the balance blocks of the pumping unit are adjusted. By the adoption of the power method, the relation is established between the adjustment amount of the balance blocks and the variation of a working fluid level HY actually measured when balance adjustment is needed and a working fluid level HY<before> obtained when balance adjustment is not needed, stored work condition information is perfected according to the model as for the same rod-pumped well, the stored information can be freely called during testing, actually measured data are used for correcting working condition parameters, and the method used for conducting practical measurement of balance adjustment of the rod-pumped well and conducting adjustment on site after measurement is achieved.
