Abstract: Sand-bearing oil flow is very common in petroleum industry.It is one of the main reasons forequipment failure and material damage,which may cause unpredictable shutdown and risk,seriously embarrasing normal production.The FLUENT software was used t0 SImUlate Sand-beaYlng O11 flow In900 bend pipes which are more likely to be wore.Characteristics of pressure and velocity fields of sand-bearing oil flows with different velocities as well as abrasion volume at pipe wall were put forward.Therelationship between abrasion volume and velocity,erosion angle was found out,providing referencesfOY Safe tYanSpOYt Of O11,control of flow parameter and prevent of pipe.
