초록 ▼

A process for creating a hot dry rock oven for the extraction of heat energy is disclosed wherein the geothermal fluid injection and withdrawal wells are brought into positive hydraulic communication during the creation of the hot dry rock oven. The oven complex is produced by fracturing the formati

대표청구항 ▼

A process for creating a fracture complex in a hot dry rock formation, comprising the steps of: (a) drilling at least one fluid injection well and one fluid withdrawal well which are approximately vertical to the approximate location within a crystalline rock formation at which a temperature exists from which useful heat energy may be extracted; (b) deviating said wells from their vertical orientation in a direction approximately perpendicular to the compass direction of the most likely fracture plane of said formation such that said withdrawal well lies above, parallel to and in approximately the same plane as the fluid injection well; (c) orientating means for fracturing said formation within said injection and withdrawal wells in alignment with the vertical direction of the anticipated fracture plane of said formation, (d) gradually pressuring the fracture means to a level slightly below the rock failure pressure of said formation and simultaneously fracturing said formation from the injection and withdrawal wells by suddenly exerting pressure in excess of said rock failure pressure in said fracturing means simultaneously to produce a single interconnecting fracture of large surface area connecting said wells for hydraulic communication.
