This paper provides an overview of the synthesis methods of hyperbranched polymers, analyzing the advantages and disadvantages of different methods. Furthermore, it describes the research progress of hyperbranched polymers in oilfield chemistry and discusses their application advantages and existing problems in various areas. Finally, it forecasts the application prospects of hyperbranched polymers in drilling, oil recovery, and gathering and transportation chemistry.
Hyperbranched polymer is a kind of polymer with a three-dimensional structure, which contains a highly branched structure and a large number of modified terminal functional groups. The desired properties can be obtained by modifying the active end groups appropriately. Hyperbranched polymers have been successfully used in the development of oilfield chemicals due to their excellent properties of solubility, rheology, temperature resistance, and salt resistance. Therefore, the application of hyperbranched polymer is helpful to the efficient development of oilfields. In this paper, the synthesis methods of hyperbranched polymers are reviewed. The advantages and disadvantages of different synthesis methods are analyzed. Furthermore, the research progress of hyperbranched polymers in oilfield chemistry is systematically described, and the advantages and existing problems of their application in polymer flooding as oil displacement agents, demulsification of crude oil, clay hydration expansion inhibition, and shale inhibition are discussed. Finally, the application prospect of hyperbranched polymer in drilling chemistry, oil recovery chemistry, and gathering and transportation chemistry is forecasted, which is expected to help the popularization and application of hyperbranched polymer in oilfields.
