In order to achieve the above purpose, the double-seal geothermal well hanger comprises a primary sleeve and a secondary sleeve, wherein the outer surface of the primary sleeve is fixedly connected with the inner surface of the secondary sleeve, the primary sleeve comprises a lead hanging sealing ring and a first fixing sleeve, and the secondary sleeve comprises a second fixing sleeve, a rubber sealing ring and a sealing surface.
Preferably, the inner surface of the lead hanging sealing ring is fixedly connected with the outer surface of the first fixing sleeve, and the outer surface of the first fixing sleeve is fixedly connected with the inner surface of the second fixing sleeve.
Preferably, the outer surface of the second fixed sleeve is fixedly connected with the inner surface of the sealing surface, and the outer surface of the second fixed sleeve is fixedly connected with the inner surface of the rubber sealing ring.
Preferably, the length of the lead hanging sealing ring is 230mm, and the diameter of the first fixing sleeve is 180mm.
Preferably, the length of the sealing surface is 150mm, the total length of the rubber sealing rings is 180mm, and the number of the rubber sealing rings is 4.
Preferably, the length of the second fixing sleeve is 260mm, and the diameter of the second fixing sleeve is 300mm.
The utility model has the beneficial effects that:
according to the utility model, through adding the design of double sealing of the hanger, the matching use of the first sleeve and the lead hanging sealing ring, the matching use of the lead hanging sealing ring and the rubber sealing ring and the matching use of the rubber sealing ring and the second fixed sleeve, the problems that the sealing of the geothermal well is invalid and surface water floods into the pump type pipe are prevented, meanwhile, the problem that the cost of the sealing structure of the hanger is high is solved, and the well cementation cost is saved.
