空气一泡沫驱的应用一直是被关注的焦点,其在采收率技术的应用领域也获得不错的效率,但是在应用安全性方面仍有需要改进的方面。本文从气体爆炸极限和氧气的消耗两个角度对该问题进行分析。分析表明,在油藏条件下,很容易控制空气与天然气的比例浓度,确保其不在爆炸范围以内,在一定程度上确保了应用的安全性;在底下空气中,使原油与地上的氧气发生化学反应,促进的原油的消耗量,同时也降低了注空气过程中存在的不安全因素。
Air-foam-driven applications have been the focus of attention, and they have also enjoyed good efficiency in the area of recovery technology, but there are still areas for improvement in application security. This article analyzes the issue from the angle of gas explosion limit and oxygen consumption. Analysis shows that under reservoir conditions it is easy to control the concentration of air to natural gas to ensure that it is not within the explosive range and to a certain extent ensure the safety of the application. In the bottom air, the crude oil is chemically mixed with the oxygen on the ground Reaction, promote the consumption of crude oil, but also reduces the insecurity of the air injection process.
