Synthesis of Hyperbranched Polymers and Prospects for Application in Oilfield Chemistry

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