A petroleum well working table is characterized in that one end of a lead screw is vertically fixed to the seabed, one end of a guide post is vertically fixed to the seabed and adjacent to the guide post, two through holes are formed in a platform, and the platform is arranged on the lead screw and the guide post in a sleeving mode through the two through holes; a motor is arranged on the portion, close to the lead screw, of the upper surface of the platform and fixed to the platform through bolts, a rotating shaft of the motor is located in the horizontal direction, a gear is arranged on the rotating shaft of the motor, the gear tooth part of the gear and threads of the lead screw are clamped, a switch is arranged on a motor shell, a power source is arranged at one side of the motor, and the motor, the switch and the power source are connected in series through wires. The petroleum well working table has the advantages of being simple in structure and convenient to use and saving time, labor and cost, and it is avoided that the platform needs to be built again for each time of lifting.
