我国微生物采油技术现状及发展前景

Present study situation and development prospects of microbiological recovery technology in China

我国大部分油田已进入高含水开发阶段 ,提高采收率技术的研究和应用迫在眉睫。国内各油田和一些研究单位已开展相当规模的微生物采油技术研究和试验 ,结果表明该项技术可适合于一定的油藏范围 ,但目前仍存在许多技术问题。分析该项技术的特点和国内研究现状 ,指出发展微生物采油技术存在的问题 ,并论述其今后发展方向。

The great majority of oil fields in eastern part of China have entered into their high water cut stage, for them it is extremely urgent to the research and application of enhanced oil recovery technology. The researchers launched a large scale study and field experiment on microbiological recovery technology, it has been confirmed that microbiological recovery technology is suitable for some oil fields, but there are still many problems in technology. The authors of this paper describe the characteristics and present studying situation in microbiological recovery technology at home, and point out the problems in the study and development prospect of this technology.
