摘　　要：通过对乳液黏温曲线变化规律进行挖掘,对凝油团形成过程定量表征,推导得出凝油团形成的数学关系表达式,将胶凝过程细化为凝油团形成和黏附两个阶段。通过蜡沉积的温度条件,发现随着沉积管壁的温度降低,凝油团形成系数逐渐增大,胶凝作用逐渐显著,即在沉积初期蜡沉积的厚度迅速增加,这与蜡沉积实验结果相吻合。Through the study on the variation of viscosity of emulsion with temperature,the formation of gel lumps was quantitatively characterized with a mathematical expression deduced.The gelation process was then divided into two stages:gel formation and gel adhesion.According to the temperature conditions of wax deposition experiment,the formation coefficient of gel lumps increased with the decrease of the temperature of deposition pipe wall,indicating the gelation effect gradually became obvious as the thickness of wax deposition grew rapidly at the initial stage of deposition.This change is in line with the experimental results of wax deposition.
