Mechanism and Adaptability of Removing Block by Enzyme-Aqueous Preparation

Abstract

Abstract: Using enzyme-aqueous preparation to remove blocks in porous media during production is a new high-tech. On the basis of latest research results in enzymology and enzyme engineering principles, combined with new understandings in contemporary reservoir engineering theory, in-depth discussion of such a blocking mechanism is made to lay a solid foundation for the practical application of the enzyme-aqueous preparation. According to the technical requirements for oilfield development, the adaptability of blocking operation is analyzed, which provides scientific basis and technical support for engineering design and field operation.

Key words: enzyme, mechanism, heavy component, interface, reservoir description, adaptability
