A COMPARISON OF THE EROSION RATE OF CASING STEELS BY SAND/OIL SUSPENSIONS

This work grew out of the observation of the erosion of oil-well components by fine sand entrained in the petroleum stream in wells off the south east coast of Trinidad (Caribbean). The effect of erosion is progressive, more sand entering the system as damage proceeds, thus engineering parts spend much of their life under conditions of steady-state erosion, component life being determined by the rate of material loss per unit time. The investigation has focused on the rate of steady-state erosion of the three casing steels under flow conditions similar to those found in oilwells and platforms. The flow rate through down-well screens is in the order of 1.5-3m/s while across chokes it may be at least an order of magnitude higher.
