Abstract
With the development of offshore oil industry, the pollution caused by frequent oil spill accidents has brought great pressure to marine ecology. How to repair the oil polluted sea area economically, efficiently and safely has become an urgent problem to be solved in marine ecological environment protection. In this paper, the main factors affecting the bioremediation of marine oil pollution are the polluted sea environment, the physical and chemical properties of oil and the types of microorganisms. The research progress of marine ecological restoration at home and abroad and the main research direction of marine oil pollution ecological restoration technology are summarized. The possible problems in the repair application are analyzed, and the further research direction is proposed.
