火烧油层技术在稠油油藏中的应用早在上个世纪早期就已经开始了,如今研究重点放在了确定能够维持燃烧前缘的最小空气流量上面。得到的最小空气流量将用于设计空气压缩机的规模。Nelson和McNeil对稠油油藏的最小空气流量做过研究,但在轻质油藏中的燃烧机理不同于稠油油藏,通常轻质油藏中的燃烧前缘不如稠油油藏中的稳定,因此最小空气流量的确定方法又有所不同。本文使用热采模拟器来确定最小空气流量,在模拟之前,做了高压变温氧化实验来确定火烧参数。模拟数据全来自于实验数据。
The use of pyrolysis oil in heavy oil reservoirs has already begun in the early part of the last century, and research now focuses on identifying the minimum air flow that can sustain the combustion front. The resulting minimum air flow will be used to size the air compressor. Nelson and McNeil have studied the minimum air flow in heavy oil reservoirs but the mechanism of combustion in light reservoirs is different from that of heavy oil reservoirs. Generally, the combustion front in light reservoirs is not as good as that in heavy oil reservoirs Stable, so the minimum air flow to determine the method is different. In this paper, a thermal recovery simulator is used to determine the minimum air flow. Prior to the simulation, a high-pressure, variable temperature oxidation experiment was performed to determine the firing parameters. All simulation data comes from the experimental data.
