摘要
在逐一筛选出符合双河油田Ⅴ上单元油藏条件的单一驱剂的基础上,研究了单一驱剂浓度变化对复合体系性能的影响,筛选出了适合双河油田Ⅴ上单元油藏条件的二元、三元复合驱油体系配方,并评价了这两种体系的基本性能和驱油性能,两种驱油体系的界面张力均达到了超低的10-3 mN/m数量级。通过对比两种复合驱技术的优劣,推荐双河油田Ⅴ上单元进行三元复合驱较为合适。
Based on the screened single flooding agent suitable for reservoir conditions of V upper unit in Shuanghe oilfield,the concentration changes effect of the single flooding agent on the performance of composite system has been studied.The formulas of the binary flooding system and ASP flooding system suitable for reservoir conditions of V upper unit in Shuanghe oilfield have been screened out,and the evaluation on the basic performance of these two systems and the displacement performance has therefore been carried out.Results show the interfacial tension of these two oil displacement systems can reach the ultra-low magnitude order of 10-3mN/m.By comparing the advantages and disadvantages of these two kinds of compound flooding technologies,ASP flooding system is recommend.
