Abstract

Abstract

The liquid silicon cement sheath samples were prepared, and the mechanical property testing experiments were carried out. Aiming at the problem of downhole failure of porous cement sheath, the porous “single-layer cement sheath” and “cement sheath-casing-cement sheath” models were established by using Flac 3D self-programming program to simulate the cement sheath fracturing process under the action of deep in-situ stress, and the deformation and failure laws of cement sheath under the coupling action of hydraulic pressure and in-situ stress were proved. The research shows that the single-layer cement sheath exhibits brittle failure under the action of stress, while under the protection of the outer casing and the cement sheath, the peak load of the cement sheath can be effectively increased. The research results provide a theoretical basis for revealing the failure mechanism of cement ring seal failure.
