Abstract

Measurement while drilling (MWD) has been widely used in petroleum drilling engineering because it can realize borehole trajectory monitoring and improve the drilling speed. However, the slurry erosion will deteriorate and shorten the life of MWD. A user-defined function (UDF) code was developed to calculate the particle properties (particle impact velocity, particle impact angle and particle impact number) and erosion depth to understand the erosion process. The results show that the Realizable κ-ε model can accurately predict the erosion profile and the erosion depth is consistent with the experiment results. Furthermore, high pressure will aggravate surface damage and expand the area of slurry erosion. It has been demonstrated that computational fluid dynamics (CFD) and experimental approach can be used to identify and explain the erosion mechanisms in different regions where the surface morphologies reveal four erosion patterns, namely, micro-cutting, cracks, pits and plastic deformation.
