微生物采油技术的进展

生物技术特别是微生物采油技术，已经引起了石油工程技术人员的空前关注。在国内外，微生物采油技术的先 导性矿场试验已初见成效，较为典型的数美国和俄罗斯，我国的吉林、胜利等油田也进行了矿场试验，增油效果鼓舞人 心。同时，随着科技的发展，一些先进的微生物学研究工具已经进入微生物采油技术的研究领域，如分子生物学、示踪 剂及可视化技术等已经成为微生物采油机理研究的重要工具。相关的石油烃降解理论、数学模型等也取得了系列成 果。微生物采油的应用也从开始的单井处理逐渐向整个区块或油田发展，并见到了明显效果。

Advancing Microbial Enhanced Oil Recovery Technology

Biological technology, especially microbial enhanced oil recovery (MEOR) technology has been paid great attention to in the world. Some pilot tests of MEOR have taken preliminary effects at home and abroad. The typical cases are found in America and Russia. Some field tests are also made in Jilin and Shengli oilfields of China, and have taken inspiring effects of incremental oil production. Meanwhile, with the development of science and technology,some advanced tools of microbiology such as molecular biology,tracer and visualization technologies etc. have entered into investigating field of MEOR,and become important tools for its mechanism studies. In addition, a series of results have been obtained in relevant theory of hydrocarbon degradation and mathematic model, too. MEOR is being applied from single well treatment toward whole block or field area with distinctive benefits.
