- Abstract:
- Hydraulic fracturing is the key technology for extracting geothermal energy, which increases the heat production by improving the permeability of the reservoir rock. In this paper, the hot dry rock thermal reservoir in Songliao Basin is taken as the research object, and a two-dimensional numerical model of hydraulic fracturing is established based on Abaqus software, and the sensitivity analysis of the parameters affecting the characteristics of hydraulic fracture is carried out by combining the orthogonal test method. The results showed that: (1) The discrepancy between the numerical simulation results and the laboratory test results was 2.6%, indicating that the model was accurate and reliable for studying hydraulic fracturing. (2) The sensitivity analysis of each parameter through the extreme difference analysis method showed that the most influential factor on the fracture width was the elastic modulus of the rock, and the fracturing fluid displacement had a minimal impact; the most influential factor on the fracture initiation pressure was the horizontal stress difference coefficient, and the elastic modulus of the rock had a minimal impact. The results of this study can provide certain guidance for hydraulic fracturing operations of the hot dry rock reservoir in the Songliao Basin
