摘　　要：首先进行三元复合驱室内岩心实验,对三类油层三元复合驱段塞组合驱油效果进行评价。然后用Petrel软件建立试验区相控地质模型,应用CMG软件中的STARS模块,对喇嘛甸油田三类油层三元复合驱不同段塞组合注入方案进行数值模拟研究。三类油层室内岩心驱油实验研究表明,天然岩心中水驱最终采收率为45.32%。进行三元段塞组合驱油最终采收率较水驱提高了12.48%。三类油层比一、二类油层更为均质,更适合以提高驱油效率为主要机理的三元复合驱。数值模拟结果表明,4种三元复合驱段塞组合方案中,方案5的最终采收率为52.67%,最终采收率比不加密井网水驱开发提高了13.94%,比加密井网水驱开发提高了9.79%,综合含水率下降了9%左右,确定方案5为最佳的注入段塞组合方案。The core experiments of ASP flooding indoor are carried out firstly to evaluate the flooding efficiency of ASP flooding slug combination for class Ⅲ reservoir, then the facies controlling geological model is established by applying Petrel software. The numerical simulation research of ASP flooding injection type of different slug combination is carried out for class Ⅲ reservoir in Lamadian oil field by using STARS module of CMG software. The core flooding experimental research indoor for class Ⅲ reservoir shows that the ultimate recovery efficiency of water flooding on nature core is 45.32%, and the ASP slug combination flooding has increased the ultimate recovery effiiency 12.48 points than water flooding. Class Ⅲ reservoir is more homogenous than Class I and Class Ⅱ, which is more suitable for ASP flooding which makes improving flooding efficiency as its main mechanics. The numericalsimulation results show that in the 4 plans of ASP flooding slug combination, the ultimate recovery efficiency of plan 5 is 52.67%, which increased 13.94 points than water flooding of non-infilling pattern, and 9.79 points than water flooding of infilling pattern, the water cut decreased about 9 points. The plan 5 is determined as the best one.
