根据等人的《粘弹性系统动力学效应的研究》证明,装有粘弹性液体的密闭容器中具有较高压力时,由于其结构的变化,开始压力逐渐降低,当压力降低到某一数值时才稳定不变。据推测,不仅是聚合物溶液,还是某些原油都具有此种观察到的现象,而且液体结构的变化能够导致其流变性的变化。为了研究各种加压,处理对象格什拉克原油流变性的影响,进行了一系列试验。用30℃予先静止热处理的原油装满管柱,并加压到100.3kgf/cm~2,压力经过18
According to et al., “The Study of Dynamic Effects of Viscoelastic Systems” shows that at higher pressures in closed vessels filled with viscoelastic liquids, the onset pressure gradually decreases due to its structural change, and when the pressure drops to a certain value Only stable. It is speculated that not only the polymer solution, but also some of the crude oil have this observed phenomenon, and liquid structure changes can lead to changes in its rheology. In order to study the effects of various pressurization and treatment on the rheology of Gershlack crude oil, a series of experiments were conducted. Crude oil pre-static heat treated at 30 ° C was packed into a column and pressurized to 100.3 kgf / cm ~ 2. The pressure was passed over 18
