Abstract: In view of the poor shear performance of current poly-α^-olefin drag reduction agent for oil, the possibility ofintroducing polymeric nano-composites into drag reduction agent for oil to improve the strength of molecule and shearperformance of drag reduction agent by using the micro-effect of nano-particles is discussed. Based on the research resultsof polyolefin nano-composites and combined with the structure and composition properties of poly-α^-olefin drag reductionagent for oil, this paper gives a review on the technical features and application value of polymeric nano-composites.The basic idea of using polymeric nano-composites technology to prepare composite drag reduction agent for oil isdiscussed, with synthesis scheme designed, key technical points analyzed, and expected performance predicted.
