A method for heating formation water. The formation water is heated, by using a horizontal well heater that has a special structural design, in such a way that the water course above a horizontal well is heated directionally and quantitatively in a delayed manner, which prevents heat energy from being transferred downwards so as to reduce the mining energy consumption of mineral resources. The horizontal well electric heater structurally comprises: an α-angle structure of a slotted screen pipe, a heat insulation system and a heating system, wherein α = arctan(hwell depth/r), hwell depth is the distance from a horizontal section of the heating horizontal well to an overlying mineral resource reservoir, and r is 1/2 of the well distance of the heating well. La présente invention concerne un procédé de chauffage d'eau de formation. L'eau de formation est chauffée, au moyen d'un dispositif de chauffage de puits horizontal qui a une conception structurale spéciale, de telle manière que le cours d'eau au-dessus d'u
