Transient Multiphase-Flow Simulation Enables Slugging Mitigation Solution

摘要

The complete paper discuses a well with a history of sand production that exhibits long cyclic slugging behavior.Whether the slugging is caused by the gap at the well's lower completion,by sand transportation,or by both is not fully understood.Dynamic wellbore modeling with sand-particle transport is essential in modeling the complex slugging behavior.Transient simulations successfully produced the slugging behavior observed in the field.Cyclic slugging was determined to be caused by the flow dynamics generated by particles of small to medium size.
