实验发现聚丙烯酰胺的存在有利于新疆克拉玛依复合驱采出原油乳状液的破乳。本文详细介绍了新疆克拉玛依复合驱原油乳状液稳定性实验及其破乳过程中聚丙烯酰胺所起的作用。三元复合驱中由于碱、高聚物的加入 ,影响破乳过程的因素十分复杂 ,本文尝试从不同剂对乳状液界面性质影响的角度出发 ,通过微量量热法及界面张力的测定 ,探讨聚丙烯酰胺对三元复合驱采出液破乳过程的影响
The experiment found that the presence of polyacrylamide is beneficial to the demulsification of crude oil emulsion produced by Karamay composite flooding in Xinjiang Autonomous Region. This article describes in detail Karamay composite crude oil emulsion stability test and its role in the process of emulsion breaking polyacrylamide. Due to the addition of alkali and polymer in ternary complex flooding, the factors influencing the demulsification process are very complex. This paper attempts to explore the influence of different agents on the interfacial properties of emulsions by microcalorimetry and interfacial tension Effect of polyacrylamide on demulsification of ASP flooding recovery fluid
