Within this study, two conditions are employed: the Mohr–Coulomb (M–C) criterion plus the multi-weak-aircraft toughness criterion for shale formations. These are generally accustomed to perform research and accomplish the optimization on the failure criteria for shale–sandstone interbedded reservoirs. The stress distribution rules fluctuate beneath different worry mechanisms, along with https://vertechs.pixnet.net/blog/posts/861489327330189632
