Crude oil gasification bacteria, including fermenting bacteria, hydrocarbon-oxidizing bacteria, reducing bacteria, and methanogenic bacteria, participate in multi-step reactions involving initial activation, intermediate metabolism, and the methanogenesis of crude oil hydrocarbons. These bacteria degrade crude oil into smaller molecules such as hydrogen, carbon dioxide, acetic acid, and formic acid. Ultimately, they convert it into methane, which can be utilized or stored as a strategic resource. However, the current challenges in crude oil gasification include long production cycles and low efficiency. This paper provides a summary of the microbial flora involved in crude oil gasification, the gasification metabolism pathways within reservoirs, and other relevant information. It specifically focuses on analyzing the factors that affect the efficiency of crude oil gasification metabolism and proposes suggestions for improving this efficiency. These studies deepen our understanding of the potential of reservoir ecosystems and provide valuable insights for future reservoir development and management.
原油气化细菌，包括发酵细菌、烃氧化细菌、还原细菌和产甲烷细菌，参与了涉及原油烃初始活化、中间代谢和产甲烷的多步反应。这些细菌将原油降解为氢、二氧化碳、乙酸和甲酸等较小的分子。最终，它们将其转化为甲烷，甲烷可作为战略资源加以利用或储存。然而，目前原油气化面临的挑战包括生产周期长和效率低。本文总结了参与原油气化的微生物群落、储层内的气化代谢途径及其他相关信息。特别着重分析了影响原油气化代谢效率的因素，并提出了提高该效率的建议。这些研究加深了我们对储层生态系统潜力的理解，为未来储层开发与管理提供了宝贵的见解。
