The invention relates to a dynamic balancing weight of a vertical long-side isosceles triangular two-dimensional surface running orbit of an oil pumping unit, belonging to the field of petroleum equipment. The dynamic balancing weight comprises a pull rod, a top rod, a pull track, a top track, a pull track wheel, a top track wheel and a balancing weight, wherein the pull track and the top track are arranged on the balancing weight and are fixed frontward to form an angle which is larger than or equal to 90 degrees; when rising, the balancing weight is pulled and pushed by the pull track wheeland the top track wheel with fixed positions, and a lever of the balancing weight completes a dynamic process of maximum-minimum-maximum corresponding to a weight value; and the relative weight of a maximum peak value acts on the whole falling process of a walking beam to perform the optimal balancing effect of the balancing weight in order to form a vertical long side of a two-dimensional surface and an isosceles triangu
