Based on the rolling restoration ,the fiber-base body mechanics model is established using casing pipe as hollow fiber, cement loop and mother earth as complex base body during the repairing of destroyed casing well. The calculation formula of stress and displacement are deduced in fiber-base body according to the solid mechanics and discussed the effect of some physics quantity to displacement such as friction coefficient by way of calculation, and have deduced the calculation formula of the cement-loop damage length according to the principle of energy balance. Thus discussing the effect of the friction coefficient and degumming power to the damage of cement loop. The practical circumstances of scene indicate that it is reasonable to using this model to research the cement mantle damage mechanism.
