Description
Изобретение относитс к устройс вам дл использовани геотермальной энергии. Известно устройство дл отбора тепла Земли, содержащее выполненную в геотермальном пласте скважину и расположенные в ней вертика ные трубы с отверсти ми дл подвод и отвода теплоносител . Недостаток такого устройства небольшие размеры зоны фильтрации охваченной циркул цией, что вызывает ее быстрое охлаждение, то есть невысока эффективность извле чени тепла Земли и малое врем ра боты скважины. Цель изобретени - увеличение ны отбора. Указанна цель достигаетс тем что в устройстве дл отбора тепла Земли геотермальный пласт снабжен непроницаемой прослойкой, преимущественно из цемента, расположенной вплотную к трубам перпендикул рно им, а отверсти дл подвода и отвода тепла выполнены по разные стороны прослойки. На чертеже изображено устройств дл отбора тепла Земли. Устройство содержит выполненную в геотермальном пласте 1 скважину 2 и расположенные в ней вертикальные трубы 3 с отверсти ми 4,5 дл подвода и отвода теплоносител . Геотермальный пласт 1 снабжен непроницаемой прослойкой 6, преимущественно из цемента, расположенной вплотную к трубам 3, перпендикул рно им, а отверсти 4 и 5 дл подвода и отвода тепла выполнены по разные сюроны прослойки. Устройство работает следующим образом . Холодный теплоноситель - пластовый флюид fвода}насосом прокачивают по трубе 3. Через отверсти 4 теплоноситель проходит в нижнюю часть скважины 2 и далее по нагретому геотермальному пласту 1, огиба непроницаемую прослойку б, нагрева сь до температуры, практически равной температуре пласта 1. Затем теплоноситель iepea отверсти 5 трубы 3 поступает на поверхность Земли, где , тепло его используют дл различных целей. Перед опусканием установки в скважину примерно в средней части пласта гидроразрывом создают горизонтальнуюThe invention relates to a device for using geothermal energy. A device for taking heat from the Earth is known, which contains a well made in a geothermal formation and vertical pipes located therein with openings for supplying and discharging a heat carrier. The disadvantage of such a device is the small size of the filtration zone covered by the circulation, which causes its rapid cooling, that is, the low efficiency of extracting the heat of the Earth and the short well work time. The purpose of the invention is to increase our selection. This goal is achieved by the fact that the geothermal layer is equipped with an impermeable layer, mainly of cement, located close to the pipes perpendicular to them, in the device for the selection of Earth heat, and the holes for heat supply and removal are on opposite sides of the layer. The drawing shows devices for the selection of the heat of the Earth. The device comprises a well 2 made in geothermal formation 1 and vertical pipes 3 located therein with openings 4.5 for supplying and discharging a heat transfer medium. Geothermal layer 1 is provided with an impermeable layer 6, mainly cement, located close to the pipes 3, perpendicular to them, and holes 4 and 5 for heat supply and removal are made along different layers of the layer. The device works as follows. Cold coolant - formation fluid f water} is pumped through a pipe 3. Through holes 4 coolant passes into the lower part of well 2 and then through heated geothermal formation 1, skirting the impermeable layer b, heating to a temperature almost equal to formation temperature 1. Then heat carrier iepea The openings 5 of the pipe 3 enters the surface of the Earth, where, heat is used for various purposes. Before lowering the installation into the well approximately in the middle part of the formation, a hydraulic fracture creates a horizontal
