Notes:
Based on the theories of fracture mechanics and composite materials mechanics, fibrouscomposite model that interacted on stratum, cement loop and casing was firstly established.Boundary conditions that the repaired force acted in fibrous composite model were also given. Theinfluences of interface damage evolution and fracture process of fiber and matrix on the cementloop mechanical properties were studied as well. Meanwhile the distributions of stress anddisplacement fields were obtained. Finally, the debonded length and variation of the optimumrepaired force were also determined, which can restrict the cement damage length to the lowestscale. The results given here can provide a reliable design references for improving the technologyof repairing casing damage well
