SAND PRODUCTION PRED ICTION TECHNOLOGY REVIEW OF WEAKLY CONSOLIDATED SAND RESERVO IR

Sand production prediction technology has been progressed from simple to complex, qualitative to quantitative. With the development of cold production and sand management, sand prediction is increasinglyurgent. This paper reviews sand production mechanism and different sand prediction methods, including engineering approach, stress-strain model, wormhole model and coupled geomechanicalhydrodynamics model, analyzes the relationship of those models and their applicability, and suggests the future research field based on the comparison of those models.
