Title:
METHOD AND DEVICE FOR HEATING FORMATION WATER DIRECTIONALLAY AND QUANTITATIVELY IN DELAYED MANNER
Document Type and Number:
WIPO Patent Application WO/2022/206713
Kind Code:
A1
Abstract:
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.
