Abstract

Abstract:

In order to solve the problem that thermal-hydro-mechanical coupling model of hot-dry-rock（HDR） reservoir fracturing is complex and it is difficult to achieve large-scale multiple cluster of fracturing network simulation, a sequential coupling simulation method of HDR fracturing is proposed. By establishing a fracture expansion thermodynamic solid sequential coupling model of single cluster fracture and multi-cluster fracture network, the thermal-hydro-mechanical sequential coupling simulation of large-scale HDR fracture network is realized. The influence of brittleness index, stress field displacement and other key parameters on the propagation of fracture network are analyzed in this model. The results showed that high temperature difference, large brittleness index and large injection pumpage could promote the propagation of fracture network, but large stress difference is not conducive to the propagation of fracture network.

Key words: hydraulic fracturing, hot-dry-rock（HDR） reservoir, thermal-fluid-solid coupling, multiple cluster of fracturing network, numerical simulation
