Abstract: The scouring resistance of resin-coated particles is an important indicator of the effectiveness of the artificial sidewall sanding control technology, but there is no professional equipment available to evaluate this indicator. Therefore, an experimental device for evaluating the erosion resistance of resin-coated particles for artificial sidewall sanding control was developed, which can simulate the effects of such factors as scouring displacement, linear scouring velocity, scouring pressure difference and scouring time on the scouring resistance of resin-coated particles for artificial sidewall. The device was applied to evaluate the scouring resistance of two types of resin-coated particles (FQ-1 and HY) used in an offshore oilfield. The experimental results were in general agreement with the actual sanding in the field, and the resin-coated particle HY was more resistant to scouring. According to the experimental results, the resin-coated particle HY was used in the subsequent sanding control of the artificial sidewall, achieving outstanding sanding control effect. The experimental device successfully developed provides a new evaluation method for the selection of resin-coated particles for artificial sidewall sanding control, and provides technical support for the large-scale promotion and application of artificial sidewall sanding control technology in offshore oilfields.
