摘要: 我国绝大多数油田在开发过程中面临采收率低、井筒及管道结蜡严重、低温储层改造时破胶不彻底等问题。微生物因其代谢产物的性能使其在油田开发中得到了较为广泛的应用,综述了微生物技术在油田提高原油采收率、清防蜡、压裂液破胶领域的研究及应用概况。说明了微生物技术在三个领域的作用机理;总结了微生物技术在油田应用时的优缺点,并且对微生物技术在未来油田开发中的研究重点进行了展望。

关键词: 微生物, 提高原油采收率, 清防蜡, 压裂液破胶

Abstract:

The development of most oilfields in China is challenged by such problems as low recovery factor,serious wax formation in wellbore and pipelinesand insufficient gel breaking during stimulation for low-temperature reservoirs. Microbes are widely used in oilfield development due to the properties of their metabolic products. This paper makes an overview of the research of microbial technology and its application in oilfields in respect of enhanced oil recovery EOR),wax removal and controland fracturing fluid gel breaking. The paper explains the mechanism of microbial technology in three areassummarizes the advantages and disadvantages of the application of microbial technology in oilfieldsand makes an outlook for the research focus of microbial technology in future oilfield development.

Key words: microbe, enhanced oil recovery EOR), wax removal and control, fracturing fluid breaking
