Progress in the research of displacement of reservoir oil by biosurfactants
摘要
Abstract
The development of the oil recovery technique for the third generation has greatly promoted the stable application of surfactant oil displacement in oil field production. Compared with the chemically synthesized surfactant,biosurfactants has the outstanding advantage of being non-toxic, which has been extensively studied and applied. The objectives of this paper are to expound the displacement mechanism,the purification and the biological application of surfactant oil displacement, and to prospect the future development of the biosurfactants. Regarding the oil displacement mechanism,the exploitation of the late reservoir recovery efficiency would be guaranteed mainly through reducing the oil-water interfacial tension,emulsifying oil residue,and enhancing the wettability reversal. As for purification,single method preparation of biosurfactants is relatively mature,yet with certain limitations,therefore,the combinations of two or more methods would be the future trend for biosurfactants’ purification technology by lowering the cost and improving the productivity. In application,biosurfactants are compounded with chemical surfactant,and then directionally injected into reservoir for oil displacement. In addition,the use of efficient nutrition agent indigenous microbial activation has been developed in recent years,to induce the surface active substance so as to enrich and displace the reservoir oil.关键词
