Aiming at the problem of shear-induced casing damage caused by standard layer shale soaking water, the theory of rock mechanics is used to establish the fluid-solid coupling calculation model of the formation-cement ring-casing of the standard interval shale interbed, obtaining the strain and deformation changes of casing shear damage, and puts forward the casing logarithmic strain exacerbated area should prompt adoption of reasonable measures to slow down the casing damage. Three-level orthogonal numerical simulation experiments were carried out for the five factors affecting casing damage, the simulation results show the critical strain data of the casing damage and the true strain data of the casing under the influence of five factors. According to the statistical principle, the predictive mathematical model of the critical strain and true strain prediction of the casing is obtained by the multiple regression method, realize the prediction of the strain state of the casing under actual working conditions is realized, and then realize casing damage early warning.

Apuntando al problema del daño de la carcasa inducido por el corte causado por el agua de remojo de capa de lutita estándar, la teoría de la mecánica de rocas se utiliza para establecer el modelo de cálculo de acoplamiento fluido-sólido de la envoltura de anillo de cemento de formación del intervalo estándar de esquisto intercalado, obteniendo los cambios de tensión y deformación del daño por cizalladura de la carcasa, y presenta el área exacerbada por deformación logarítmica de la carcasa, debe impulsar la adopción de medidas razonables para reducir el daño de la carcasa. Se llevaron a cabo experimentos de simulación numérica ortogonal de tres niveles para los cinco factores que afectan el daño de la carcasa, los resultados de la simulación muestran los datos críticos de tensión del daño de la carcasa y los datos reales de tensión de la carcasa bajo la influencia de cinco factores. De acuerdo con el principio estadístico, el modelo matemático predictivo de la deformación crítica y la predicción de deformación verdadera de la carcasa se obtiene mediante el método de regresión múltiple, se realiza la predicción del estado de deformación de la carcasa en condiciones de trabajo reales y luego se realiza la advertencia temprana de daños en la carcasa.
