摘要: 使用2,2,6,6-四甲基哌啶酮作为自旋探针,在不同温度下测定了探针的ESR波谱并计算了高分子链松驰特征温度死T50G,发现(T50G越小,减阻效率越高。

Abstract: The segment motion of drag reduction agents of crude oil is considered to correlate to drag reduction efficiency. In this paper, 2,2,6,6-tetramethylpiperidone was used as a spin probe. The ESR spectra of probe were recorded at different temperatures and the values of T50Gwere calculated. It was discovered that the lower the T50G, the higher the drag reduction efficiency.

Key words: ESR, Spin probe, Drag reduction agents
