Wellhead leakage treatment device

The utility model relates to an oil field oil-water well wellhead device, in particular to a wellhead leakage treatment device. The device comprises a pressing connector, a piston cylinder, a piston, a sealing ring, a baffle, a piston groove, a one-way sliding ring, a screw thread head, an insertion pipe, an insertion pipe left-hand thread connector, a hanger, a flange, a packing, a pressing cap, a jackscrew, a four-way joint and a hanging short section. By adopting the device, the well mouth leakage control time can be shortened, the well mouth overflow discharge flow is reduced, the treatment cost of returned well fluid is saved, the formation pressure is maintained, energy conservation and emission reduction are realized, and the environment is protected. The device can maintain the wellhead and replace valves and parts under the condition that no pressure exists in the wellhead, and the service life of each part of the wellhead can be prolonged. 本实用新型涉及油田油水井井口装置，具体涉及一种井口治理渗漏装置。所述装置包括打压接头、活塞筒、活塞、密封圈、挡板、活塞槽
