TL;DR: In this paper, a numerical model was used to represent the actual heterogeneous structure of a physical specimen, and the initiation position and process of propagation of cracks influenced by geostress differences and heterogeneity was discussed.

TL;DR: In this paper, an analytical model considering the well completion steps is established to study the integrity of cement sheath as a two-layer casing-cement system, and the effect of mechanical and geometrical parameters of casing and cement are further investigated through a sensitivity analysis.

TL;DR: In this paper, a novel elastic-plastic model incorporating the effects of drilling, cementing, and dramatic temperature change of the well system during the hydraulic fracturing is established to describe the stress of cement sheath.
