Through the alpha structure of the slotted sieve tube and the design of a heat insulation device at the lower part of the sieve tube, heat energy is prevented from being transferred to the lower part of the plane where the heating horizontal well is located; changing the radiation direction of the heat energy, and gathering the heat energy upwards to form a bundle which is concentrated to the overburden stratum to be heated; the formation water is heated gradually, so that the preheating time of the formation water and the heat energy loss of the formation water are reduced; the heat loss accounting for half of the total heat energy can be reduced; through the design of an angle alpha, the water body in the range of alpha is heated gradually, so that the preheating time of formation water and the heat energy loss in the production process can be reduced; the scale removal technology of the electromagnet saves electric energy and the cost of the ferrite permanent magnet; the permanent magnet formed by heating the coil under the condition of electrifying the direct current can be reused, and new value is created.)
