The utility model discloses a screw pump drainage well mouth operating platform used on a floating drilling platform. The well mouth operating platform is arranged over a testing tubular column on the floating drilling platform, and comprises a fixed base and an operating platform board connected with the fixed base, and the fixed base is fixed to the floating drilling platform. A central hole allowing a sucker rod to pass through is formed in the operating platform board, the central hole is arranged over the testing tubular column, and a slip used for fixing the sucker rod entering the testing tubular column downwards is arranged on the operating platform board. Fastening dismounting/abut fastening can be achieved smoothly when the sucker rod is pulled out or enters in the floating drilling platform, and therefore the screw pump drainage technology is applied to the floating drilling platform.
