Thermoelastic Analysis of a Cracklike Reservoir in a Hot Dry Rock During Extraction of Geothermal Energy

The fracture mechanics study of the problem for a fluid-filled cracklike reservoir is made by including the thermoelastic effect. A two-dimensional crack is considered as a model of the vertical cracklike reservoir in the earth’s crust, and the crack is analyzed on the basis of the theory of quasi-s...

Description
Summary:The fracture mechanics study of the problem for a fluid-filled cracklike reservoir is made by including the thermoelastic effect. A two-dimensional crack is considered as a model of the vertical cracklike reservoir in the earth’s crust, and the crack is analyzed on the basis of the theory of quasi-static thermoelasticity. The fluid temperature at the outlet and the rock temperature are obtained. The variations of the shape and volume of the reservoir against time are shown in graphs.
