Dynamic Changes in Stress and Failure Evaluation of Cement Sheath in Long Horizontal Sections

The wellbore sealing integrity fails frequently in the fracturing process of shale oil and gas horizontal wells.However,there is less research on the evaluation of the sealing integrity of cement sheath in long horizontal sections under temperature-pressure coupling conditions.In this paper,a model...
