摘要

This study identified shape memory alloys (SMAs) as a choice material for production facilities. With a focus on stand-alone screens, it examines SMA’s special characteristics and potential roles during sand erosion. Sand particle shape, impact velocity and the mechanism were highlighted as top design considerations as increasing impact velocity was noticed to increase the wear of SMA, and risk of localized leaks and deformation. Bigger particle spheres had more effect on the wear rate of SMAs than smaller spheres, regardless of the increased roughness of the smaller spheres. Short drags and indentation were noticed on SMA surfaces on an increased energy impact. SMAs also presented higher safety integrity levels (SIL) compared to traditional materials for downhole tools, valves, actuators, pipes and BOPs. Still, they experienced nonlinear failures at the micro-scale affecting their mechanical integrity and propagating wear during high particle impact. The study reveals that SMAs are relevant for fail-safe operations and emergency response for hazard prevention and concludes that SMAs have the potential to revolutionize the oil and gas industry’s approach to sand erosion mitigation and their use will increase safety, reduce downtime, and decrease environmental impact.
