The invention discloses an oil extraction method of weight adding under a pump and an oil well pump with weight adding under the pump, used in pumping units and oil pumped wells in the petroleum industry. In the oil extraction method of weight adding under the pump, a weight adding bar is connected under an oil well pump plunger assembly to reduce the bend and the deformation of a pumping rod string. The oil well pump with weight adding under the pump comprises a pump cylinder assembly, the plunger assembly and an auxiliary mechanism under the pump. The plunger assembly is provided with a liquid outlet valve and a liquid inlet pump, an upper plunger and a lower plunger are connected with a connection bar through a plunger lower joint to connect the weight adding bar under the plunger assembly. The method uses the liquid inlet valve with an offset structure outside the pump while adding weight under the pump, thereby lightening the eccentric wear of pipes and bars and reducing the stroke loss. Due to the weight adding bar arranged under the pump, the pumping rod is kept in the straightening state all the time under the action of gravity, thereby lightening the mutual abrasion of the pipes and the bars. The weight adding under the pump can reduce the elastic bending and deformation of the pumping bar string, thereby reducing the stroke loss and enhancing the filling factor of the oil well pump.
