Shallow gas recycling and distributing structure for offshore oil drilling

The invention discloses a shallow gas recovery and diversion structure for offshore oil drilling, which comprises a diverter shell, a diverter assembly positioned in the diverter shell, a flare tube communicated with the upper end of the diverter assembly, and a reflux groove communicated with the flare tube, and the reflux groove is connected with an inner side platform of a cantilever beam. The device further comprises an overhead channel for workers to pass through, one end of the overhead channel is detachably connected with the cantilever beam inner side platform, and the other end of the overhead channel is detachably connected with the flow divider shell. The shallow gas recycling and distributing structure for offshore oil drilling solves the problems that in the prior art, a flow divider is large in mounting and dismounting operation difficulty, high in risk and the like, and the purpose of reducing the risk of dismounting and mounting the flow divider on site is achieved.
