The Research of Crustal Stress Distribution Based on the Coupling Effect of Geothermal Field and In-Situ Stress Field
Taking the Wumishan reservoir of Renqiu buried hill as example, rock mechanics and heat transfer were combined in this article, the coupling effect of geothermal field and in-situ stress field was researched, and the numerical model of geothermal field and in-situ stress field coupling was discussed, based on those, the stress numerical simulation was carried out considering the impact of the geothermal field. The results show that the crustal stress based on the coupling effect of geothermal field and insitu stress field is consistent with the actual measurements, the direction of the main max level crustal stress in the middle-south is the north-east and in the north is the north-west, the main max level crustal stress value is between -64MPa and -114 MPa in this area;the direction of the main min level crustal stress in the middle-south is the north-west and in the north is the north-east, the main min level crustal stress value is between -35MPa and -95 Mpa.
