本文介绍了微生物提高石油采收率作用机理与现场试验。根据微生物现场试验效果,提出瓦窑堡油田长2油层可以利用微生物驱油来提高采收率,并利用实例证实了它在低渗透油田的可行性。
This article describes the mechanism of microbial enhanced oil recovery and field experiments. According to the results of the field experiment of microorganisms, it is suggested that microbial flooding can be used to enhance oil recovery in Chang 2 reservoir of Wayaobao Oilfield, and the feasibility of its application in low permeability oilfields is confirmed by an example.
