Abstract: The creep happens in the deep sandstone formation of an oilfield in South China Sea. It is necessary to analyze the sandstone creep behavior to ensure the safety drilling in the field. Creep experiments were carried out with sandstone cores from the field, and creep rates under different differential stress were determined. The experimental data were treated by regression based on the Xiyuan model with a high regression accuracy. The creep rate of the oilfield sandstone based on the Xiyuan model shows that an improving drilling fluid density can greatly improve the safety drilling cycle. The regular tripping and casing and cementing shrinkage hole can also be used to prevent the sandstone creep.
