摘要
河口采油厂沾3块的开发形势和油藏特点非常适合开展微生物采油,室内在模拟油层环境的条件下,开展沾3块内源微生物可激活性研究和驱油能力研究,从实验结果得出沾3块内源微生物可以用现有的激活剂激活,并且能起到显著的增油作用,静态模拟实验的提高采收率幅度达到10%,动态模拟实验的提高采收率幅度达到5.1%。并通过实验现象的分析,对微生物提高采收率的机理进行了探讨。
The reservoir features of Zhan 3 block are very suited to develop microbial oil production. In the condition of simulation reservoir environment, the activation ability and oil displacement ability of endogenous microorganism were studied. The experiment results show that the endogenous microorganism can be activated by using current activation agent in Zhan 3 block and can enhance oil production. In static simulation test, the recovery efficiency is improved by 10% .The recovery efficiency of dynamic modeling test is improved by 3. 1 % . Through analyzing the experiment results, the mechanism of enhanced oil recovery on endogenous microorganism is discussed.
