The invention relates to a multi-stand-column semi-submersible platform for a cylindrical floating box. The cylindrical floating box is arranged at the bottom of the semi-submersible platform. The inner portion of the cylindrical floating box is divided into a plurality of watertight cabins used for storing well drilling materials, consumables, anchor cables and ballast water. The circumference of the top of the cylindrical floating box is connected with the bottom of a platform deck through four or more stand columns. Branch cabins used for storing fresh water and drilling mud materials and elevator passageways penetrating the cylindrical floating box and the top of the platform deck are arranged in the stand columns. A generator set, an electrical equipment room and a drilling support device are arranged in the platform deck. A drilling or oil-gas production facility is arranged on the platform deck. The multi-stand-column semi-submersible platform is high in loading capacity adaptability, low in center of gravity, good in stability, small in movement range, high in overall strength, insensitive in environment direction, capable of changing the draft, capable of being towed by a tug or conducting self-propulsion through a propeller, simple in structure, convenient to construct and suitable for drilling and oil-gas production work of oil-gas fields in shallow sea and deepwater sea areas.
