内源菌采油技术研究

Study on indigenous bacteria oil recovery technique

内源菌驱油技术是近2年来国内发展较快的一项提高采收率的技术。通过基础配方设计和性能评价室内实验,了解了不同营养源及浓度选择对配方体系激活效果的影响,推出适合巴48和巴38断块激活内源菌营养体系配方激活剂Ⅰ。该激活剂不仅能有效激活巴48、巴38断块采出液中的内源菌,而且具有良好的乳化性能和降黏性能。

Indigenous bacterium enhancing oil recovery develops rapidly in recent two years in China. Based on the design of basic formulation and properties evaluation experiments, the influences of different nutritional resources and concentrations on the activation of formulation system are studied in this study. The results show that the activator I is suitable for activating the indigenous bacterium nutritional system of block 48 and block 38 ,which not only can activate the indizenous bacterium of block 48 and block 38, but also has good emulsifying property and the reduced viscidity.
