Abstract

This paper conducts a multi-dimensional discussion on petroleum recovery technologies. It first elaborates on the current situation of petroleum pollution, including the leakage risks in various links from exploration to processing, major leakage incidents from 2000 to 2025, their impacts on marine, terrestrial, and freshwater ecosystems, as well as the severe hazards to the environment, human health, and economic development. Then, it analyzes the necessity of petroleum recovery and utilization, involving aspects such as resource scarcity, ecological protection, and policy promotion. Subsequently, it details the principles, effects, influencing factors, advantages, and disadvantages of existing physical, chemical, biological, and combined recovery technologies, and evaluates the removal rates and costs of various technologies. It also points out the bottlenecks faced by current technologies, such as poor environmental adaptability of microorganisms in biological recovery, high energy consumption in physical and chemical recovery, high costs of emerging technologies, as well as issues in policies and standardization. Finally, it prospects that future technologies will develop towards genetically engineered microorganisms, nanomaterials, and intelligent monitoring and restoration, emphasizing the importance of accelerating technological innovation and standardization.
