Stress Evolution and Integrity Evaluation of Cement Sheath Under Alternating Temperature–Pressure Coupled Loads During Multi-Stage Fracturing in Shale Gas Wells

Based on measured data from a shale gas well, this study develops a wellbore temperature cycle model and a temperature–pressure coupled finite element model to evaluate cement sheath stress during multi-stage fracturing. Dynamic temperature and pressure boundaries are applied to calculate radial and...
