Damage Mechanism and Sensitivity Analysis of Cement Sheath Integrity in Shale Oil Wells During Multi-Stage Fracturing Based on the Discrete Element Method

As the retrieval of unconventional oil and gas resources extends to the deep and ultra-deep domains, the issue of cement sheath failure in shale oil wellbores seriously endangers wellbore safety, making it imperative to uncover the relevant damage mechanism and develop effective assessment approache...
