<jats:p>The shale reservoir in boxing depression has developed faults and fissures, and the distribution of in-situ stress is complex. Therefore, in this paper, studies on in- situ stress distribution of the shale reservoir in boxing depression based on the actual logging data, and maps the changes of in-situ stress and lateral pressure coefficient with the depth. The results show that the maximum horizontal principal stress in the study area is about 58∼67MPa. The minimum horizontal principal stress is about 55∼63MPa. The in-situ stress in the study area has a linear relationship with depth as a whole. The stress state accords with the relationship that the vertical principal stress is greater than the maximum horizontal principal stress is greater than the minimum horizontal principal stress. The coefficient of lateral pressure has a hyperbolic relation with depth. The research results can provide scientific basis for well pattern layout of oil and gas exploration and development in shale reservoir and reservoir reconstruction plan design.</jats:p>
