摘　　要：根据注空气-空气泡沫提高采收率的基本原理，分析了油藏注空气-空气泡沫驱的安全风险，以及国外两起注空气安全事故的原因，针对注空气中的各个安全节点如空压机、管线、注入井及生产井的风险提出了相应的安全控制技术，以逐步形成注空气-空气泡沫提高采收率的配套技术。Based on the philosophy of improving the recovery rate by air-aerated foam stimulation, the safety risks of reservoir oil driving by the method of air or aerated foam injection have been analyzed and two eases of air injection accident which occurred abroad have been studied and the causes of these accidents analyzed. Against the safety risks during air injection such as the risk with air compressor, air line, injection well and production wells, the corresponding safety control measures have been proposed in order to gradually form the accessory technology for improving the recovery rate by air-aerated foam injection method.
