The permeability of coal reservoirs is largely controlled by the present-day in-situ stress field to a great extent. The Daning-Jixian area of eastern Ordos Basin is rich in coal-bed methane resources, However, The lack of ground stress studies in this region, makes it difficult for coalbed methane to be developed effectively there. To identify the characteristics of the present-day in-situ stress field in the Daning-Jixian area, this study uses 3D finite element numerical simulation to predict the present-day in-situ stress distribution in the 5# coal seam of Lower Permian Shanxi Formation. The results indicate that the present-day in-situ stress indicates a normal faulting stress regime in the 5# coal seam. The 5# coal seam in the eastern Ordos Basin has a horizontal maximum principal stress between 15.4 MPa and 21.6 MPa, and a horizontal minimum principal stress between 9.8 MPa and 14.4 MPa. The distribution of ground stress may be impacted by how complex tectonic deformation is. Hydraulic fractures in the study area propagate vertically along the NNW-SSE direction under the present-day in-situ stress condition. The stress difference in the 5# coal seam in the study area is mostly less than 6 MPa, which favors to generate a complicated fracture network. The coal permeability declines exponentially as effective in-situ stress rises. Coalbed methane is anticipated to build up in the southeast of the study region, which is far from the fault and a stress reduction area, creating a rich area for coalbed methane reserves. The study results can offer a geological foundation and scientific guide for the development of coalbed methane in the study area.
