METHOD OF GEOTHERMAL ENERGY UTILIZATION Russian patent published in 2001 - IPC

FIELD: engineering means for utilization of geothermal energy. SUBSTANCE: method includes search of geothermal anomalies and sinking of boreholes to geothermal section for lifting of heated liquid. Boreholes are sunk to depth of 100-200 m. Received from bottom of these boreholes are signals produced by geological structures such as acoustic, electromagnetic, heat and total torsion radiations. Researched structures are treated with acoustic loads. Produced in geological structures with detected geothermy is artificial geothermal anomaly horizon due to introduction into rocks of this horizon of hydraulic reacting substance. After its polymerization hydraulically impermeable screening horizon is formed. Introduced to above screening horizon with the help of boreholes is hydraulically reacting heat-liberating material. Boreholes are drilled in structure of said abnormal horizon. Formed at ends of boreholes in structure of geothermal horizon is cavern. Introduced into boreholes and cavern is flexible main line. Base of main lain is made in the form of heat exchanger. Main line is connected with supplying-withdrawing coaxial main line connected on ground surface with user. EFFECT: higher efficiency of utilization of geothermal energy due to reduced loss of heat during recovery of energy and control of heat characteristics of geothermal zones. 3 cl, 5 dwg
