摘要
为了解二元复合驱中乳化程度对驱油效率的影响,配置了表面活性剂浓度分别为0.1%、0.2%、0.3%的3种乳化程度不同的二元体系。通过对3种体系的界面张力、析水率、稳定性和驱油效率进行研究评价,实验表明:乳化程度越高,析水率越低,稳定性越好,驱油效率越高,提高采收率效果越好。
In order to understand the effect of the degree of emulsification on the displacement efficiency in binary composite flooding,configure three binary systems with different emulsification levels of surfactant concentrations of 0.1%,0.2%,and 0.3%.By evaluating the Interfacial tension,water separation rate,stability and oil displacement efficiency of the three systems.Experiments show that the higher the degree of emulsification,the lower the water separation rate and the better the stability.The higher the oil displacement efficiency,the better the effect of enhanced oil recovery.
