Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of functional polymers. More specifically, the present invention relates to a kind of hydrophobic association polymer with multiple ring structure side chains, also relates to the preparation method of said hydrophobic association polymer, also relates to said hydrophobic association polymer in oil displacement agent the use of. [0003] 【Background technique】 [0004] The oil industry is the blood of economic development. With the development and progress of the times, the use of oil by humans is increasing year by year. As a non-renewable resource, few large oil fields and new reserves have been discovered in recent years. The inability to provide sufficient oil reserves to meet the increasing demand for crude oil consumption has led to increasingly prominent contradictions between oil supply and demand. Therefore, under the circumstances that the number of new oil fields is decreasing and crude ...
