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.
Abstract
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 tempera-ture 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 ob-vious 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.
