The harm of erosion-corrosion to the oil industry was introduced, the factors affecting erosion-corrosion were discussed, such as solid phased particles factor, hydrodynamics factor, material factor, and so on. The research progress in computational fluid dynamics (CFD) method for the pipeline erosion-corrosion research was summarized;its advantages and disadvantages were pointed out. CFD numerical simulation provides a new method for study on the corrosion protection. The simulation can predict the erosion-corrosion occurring and development, which can provide reliable theoretical basis for pipeline optimization design and corrosion protection.
