摘要
管道石蜡沉积会使管道流通面积变小,摩阻增大,降低管道输送能力,甚至造成重大的经济损失及安全问题。结蜡层中的沥青质对蜡的存在形式具有重要影响。沥青质结构复杂多样,导致其极性、表面活性有很大的不同。本文从沥青质的分子结构、沥青质对结蜡的促进作用和抑制作用方面展开综述。
Paraffin deposits in pipelines will reduce the flow area of pipelines,increase frictional resistance,reduce pipeline transportation capacity,and even cause significant economic losses and safety problems. Asphaltene has an important influence on the form of the wax. The structure of asphaltene is complex and diverse,leading to great differences in its polarity and surface activity. Interaction between asphaltenes and paraffin molecules has dual effects on paraffin precipitation. The structure of asphaltene,the promotion effects and inhibitory effects of asphaltenes on the paraffin precipitation was reviewed.
