The utility model relates to an oil pumping device driven by a submersible motor, which comprises the submersible motor, an output shaft of the submersible motor is a hollow shaft, an external threadis arranged on the side surface of the outer circle of the middle part of the output shaft, a movable cylinder is sleeved outside the output shaft, an internal thread is arranged on the side surface of the inner circle of the middle part of the movable cylinder, and the internal thread is matched with the external thread for use; a fixed valve is arranged in an inner cavity of the output shaft, amovable valve is arranged in an inner cavity of the movable cylinder, and the movable valve is located above the fixed valve. The side face of the outer circle of the movable cylinder is sleeved withan outer cylinder, the top of the outer cylinder communicates with an oil pipe, the outer cylinder is fixedly connected with the oil pipe, and a check valve is arranged at the end, close to the outercylinder, of the oil pipe; and a guide device is arranged on one side of the movable cylinder. According to the utility model, structures such as a gear motor and a crank connecting rod can be avoided, and the space occupation of the pumping unit on the ground can be reduced; the problems that when a crank-link mechanism is adopted, a sucker rod and an oil pumping pipe are seriously abraded, and the sucker rod is prone to breakage can be solved.
