稠油热化学开发是继稠油热采技术之后,对该类非常规油藏更为有效的开发手段。稠油开采用耐高温化学剂要求有较高的降低油/水界面张力的能力,而且要耐温、耐盐同时兼具对稠油的降粘作用。因此,通过室内实验研究该类驱油剂界面性质、耐温性能、耐盐性能以及降粘性质,明确其提高驱油效率的主要机理和作用机制,具有重要意义。
The development of heavy oil thermal chemistry is a more effective development method for such unconventional oil reservoirs following the thermal recovery of heavy oil. Heavy oil mining with high temperature chemicals require a higher ability to reduce the oil / water interfacial tension, but also to temperature, salt at the same time both viscosity reducing effect on heavy oil. Therefore, it is of great significance to study the interfacial properties, temperature resistance, salt tolerance and viscosity reduction properties of these oil displacement agents through laboratory experiments, so as to clarify the main mechanism and mechanism of enhancing oil displacement efficiency.
