摘要
Abstract
Condensation point and pour point indicated with temperature,which were conditional indexes,were temperature cut-off point at which the physical state of crude oil was shifted.The pour point was viewed as an important parameter to measure the cold flow properties of crude oil and crude oil temperature control in China.In order to in-depth understanding of the mechanism of the microstructure of waxy crude oil,it was necessary for the waxy crude oil condensation point/pour point crude oil composition and microstructure to study the relationships.The pour point experiments of six typical waxy crude oils of Daqing were made,and the experimental laws were summarized,and gray system theory directional correlation was used to analyze the influence of wax crystal morphology/structure and composition of crude oil condensation point/pour point.The long-distance transportation of crude oil in the process flow was improved.关键词
