摘要
运用NETZSCH STA 409PC同步热分析仪针对新疆克拉玛依油田红浅扩大试验区中的稠油样品在氧化过程中高岭石的影响,分析测试。研究结果表明,高岭石的加入影响了稠油的低温及高温氧化反应,使稠油的低温氧化DTA峰值温度从437.6℃增加为455.4℃;高温氧化DTA峰面积显著减小,峰值从607.8℃减小为597.8℃;高岭石含量的增加,有利于降低稠油的低温,高温氧化的DTA峰值温度。随着升温速率的增加,混合样品中稠油的低温,高温氧化及高岭石脱羟基反应呈现为动力学过程。研究结果有助于深入认识原油的氧化过程,对提高采收率和推动稠油油藏的有效开发具有重要的意义。
NETZSCH STA 409 PC thermal analyzer is used to study the effect of Kaolinite from the Hongqian area of Karamay oilfield in Xinjiang on heavy oil samples during oxidation.It shows that the addition of kaolinite affects the low-temperature and high-temperature oxidation reaction of heavy oil.The DTA peak temperature of heavy oil is increased from 437.6 ℃ to 455.4 ℃ during the low temperature oxidation(LTO) stage,whereas the peak area of DTA is decreased significantly with the peak temperature reduction from 607.8 ℃ to 597.8 ℃ during the high temperature oxidation(HTO) stage.The increase of kaolinite content is helpful to reduce the DTA peak temperature of LTO and HTO of heavy oil.With the increase of the heating rate,the reaction of heavy oil oxidation and kaolinite dehydroxylation in the mixtures shows a dynamic process.The research enhances the understanding of crude oil oxidation process and is of significance in oil recovery and promotion of effective development of heavy oil reservoirs.
