本文介绍了一种新的注空气技术———低温氧化 (LTO)法。通过与油藏中残余油发生LTO反应除去注入空气中的氧 ,可提高深层低粘油藏的原油采收率。LTO反应产物“烟道气”可驱替原油。本文通过使用北海的四种低粘原油获得了LTO反应动力学和原油采收率的初步结果。此外 ,本文还讨论了海上注空气的一些安全问题 This article describes a new air injection technology - low temperature oxidation (LTO) method. The LTO reaction with the residual oil in the reservoir removes the oxygen injected into the air and enhances the oil recovery of the deep, low viscosity reservoirs. LTO reaction product “flue gas” can be used to displace crude oil. In this paper, preliminary results of LTO reaction kinetics and crude oil recovery are obtained using four low viscosity crude oils from the North Sea. In addition, some safety issues related to air injection at sea are also discussed
