Leakage stopping device for subsea production

The invention relates to a leakage stopping device, in particular to a leakage stopping device for subsea production.The leakage stopping device comprises an oil well and an oil pipe and is characterized in that the lower portion of the oil pipe is provided with an upper expansion adhesive control ring and a lower expansion adhesive control ring; expansion sponge bodies are arranged between the upper expansion adhesive control ring and the lower expansion adhesive control ring; the lower expansion adhesive control ring is connected with springs by means of upper spring controllers; and the springs are fixed at the bottom of the oil pipe by means of lower spring controllers. The leakage stopping device for subsea production has following beneficial effects: operation is performed easily at low cost; quick and good leakage stopping effects are achieved; and the leakage stopping device is not only used for oil leakage in a gulf but also used for oil leakage and gas leakage in case of emergencies.
