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

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.
