Research on Numerical Simulation of the Crustal Stress Distribution

Article Preview

Abstract:

In this paper, the Renbei Ordovician reservoir of Renqiu buried hill of Raoyang Depression was taken as an example, the numerical model of geothermal field was constructed. Then, the stress numerical simulation was carried out considering the impact of the geothermal field. The results showed that the result of numerical simulation of crustal stress is consistent with the actual measurements, the maximum horizontal principal crustal stress focuses between-49MPa and-96MPa in this area. The minimum horizontal principal crustal stress focuses between-65MPa and-115 MPa. The total stress focuses between 59Mpa and 95MPa, showing an obvious gradient distribution and a decreasing trend from the northwest to the southeast. The fault zone and the fault transition zone have an obvious partition function to the contour lines of the stress intensity.
