Under variable mechanical conditions, the shear behavior of mixed-layer clays exhibits considerable complexity, underscoring the need for in-depth investigations. This paper presents a molecular-scale study on the behavior of interstratified illite-smectite minerals, simulating a geotechnical shear setup at the molecular level. Multiple molecular models were constructed to explore the effects of water content and illite layer proportions, effectively replicating stages of the illitization process. The results reveal that the mixed-layer clays exhibit clear stick–slip behavior during shear simulation. Models with low illite content demonstrated relatively similar shear characteristics, while higher illite content led to a significant reduction in nanoscale cohesion and a slight increase in friction coefficient. Pure illite exhibited the highest shear strength among the studied materials, with a friction coefficient and cohesion of 0.111 and 0.172 GPa, respectively. Furthermore, the illitization process was observed to progressively enhance the shear modulus, ranging from 0.63 GPa to 26.81 GPa under various hydrostatic pressures.

Accurately describing the three-dimensional anisotropic deformation of rocks within ductile domain is of great significance for deep underground engineering. Therefore, a three-dimensional fractional elastoplastic constitutive within ductile domain is proposed in this study, including yield function and fractional flow rule. The ductile yield function is based on the modified Mohr-Coulomb criterion and generalized Matsuoka-Nakai deviatoric function. The deviatoric stress of yield surface is negatively correlated to hydrostatic pressure, but positively correlated to Lode angle. The yield surfaces in both meridian and deviatoric planes evolve with the plastic internal variable, accurately capturing the stress state during hardening. Two different fractional orders are used to control the plastic flow direction within meridian and deviatoric planes, represented by dilation angle and plastic deflection angle, respectively. These fractional orders are determined based on the relationship between plastic shear strain and volumetric strain, and they vary with the plastic internal variable, effectively capturing the plastic flow direction throughout hardening. The proposed model is validated using green sandstone data from hydrostatic compression and true-triaxial tests.

This study reveals the influence of various factors on reservoir stimulation effectiveness and employs impact assessment to compare the relative importance of each factor. The results indicate that wider natural fracture zones (NFZs) and smaller angles between the NFZ and hydraulic fracture propagation direction increase the difficulty for hydraulic fractures to breach the NFZ barrier and continue propagating. This results in more activated discrete natural fractures, greater fluid diversion, greater nonuniform hydraulic fracture propagation, an increased risk of limited fracture growth, and an increased probability of interwell interference. A higher fracturing flow rate and fracturing fluid viscosity result in less interfracture stress interference and greater uniformity of multifracture propagation in a less complex fracture network. Larger proppant particles increase the risk of proppant plugging. Blockages are prone to occur in narrow fracture sections, hindering the continuous injection of fracturing fluid. Staged pumping can prevent proppant accumulation at the fracture tip and prevent inadequate near-wellbore proppant placement caused by pump shutdown.

The interfacial bonding behavior between the cement sheath and casing is a critical factor governing the long-term integrity of the wellbore. This paper develops a damage model for the double-layer casing-cement sheath interface under non-uniform loading based on peridynamic theory. The model numerically characterizes the evolution mechanism of interface damage under non-uniform stress. Laboratory tests were conducted using a Digital Image Correlation (DIC) system to capture the strain evolution on the casing-cement sheath surface during radial compression. The results indicate that the peridynamic simulation of damage at the double-layer casing-cement sheath interface under non-uniform loading is in strong agreement with the DIC strain measurements. From the perspective of strain accumulation and damage morphology, increasing the outer casing radius enhances the overall structural stiffness. Strain accumulation at the inner casing-cement interface accelerates, with damage concentrated at the interface. while damage within the cement sheath primarily propagates along the 90° and 270° loading directions. In contrast, an increase radius of the inner casing reduces the constraint on the cement sheath, making the casing more prone to “ovalization” deformation. This extension of the stress transfer path slows strain accumulation at the inner casing–cement interface, with damage propagating along the 0°, 90°, 180°, and 270° directions. Experimental results further indicate that the load-bearing capacity of the model with an inner casing is at least 2.5 times higher than that of the model without an inner casing.
