摘要

Poly a-olefin as drag reduce agent (DRA) with more than 6 million molecular weight would lost most of drag reducing rate after shearing degradation.Commonly, adding DRA was adapted after shearing degradation.Composites combining many unique physical and chemical properties could offer possible way to develop DRA with better performance.The preparation, drag reducing rate and anti-shearing of Poly α-olefin/SiO2 nanocomposite as DRA were investigated in our research.Modified SiO2 by silane coupling agents and poly α-olefin were combined together by interface compatible agent.Drag reducing rate and anti-shearing were analyzed through diesel experimental loop.It was shown by drag reducing test that synthesized composite DRA had higher drag reducing and flow increase performance, and it presented better anti-shearing ability.With 5% SiO2, DRA had the best performance.The flow increase rate had raised 29.7%, the drag reducing rate had raised 18.6%, and the anti-shearing had raised 200%.It was thought that synergistic effect had occurred after combination of nano SiO2 and poly α-olefin, which could upgrade the composite DRA performance.
