摘要：

运用实验室自主研发的高温高压热跟踪补偿仪器开展了吉七稠油在近绝热条件下的低温氧化实验,分析了初期温度、石英砂、岩屑和介质比表面对油样低温氧化热释放的影响。实验结果表明：温度是影响原油低温氧化放热的重要因素,随着初期温度的增加,耗氧能力显著增加,氧化放热量增加,系统压力降低。在初期温度为160 ℃时,前26 h内温度升高10.7 ℃,系统压力降低2.26 MPa,产出气中氧气体积分数仅为2.5 %,这表现出稠油明显的低温氧化热效应。介质比表面的增加与石英砂和岩屑的加入均能有效促进油样低温氧化热效应,但介质比表面效应对稠油低温氧化放热的贡献较小。

Abstract:

The influences of temperature, quartz sand, detritus and specific surface area of medium on thermal release caused by low-temperature oxidation of heavy crude oil of Jiqi Oilfield have been investigated by self-designed high-temperature and high-pressure heat tracking compensation equipment. The results show that the temperature is the significant factor regarding heat release induced by low-temperature oxidation of heavy crude oil. As the initial temperature increases, the increase in capability of oxygen consumption and heat liberated as well as the reduction in pressure. When the initial temperature is 160 ℃, the temperature is improved by 10.7 ℃ in the first 26 hours coupled with the pressure reduction of 2.26 MPa and 2.5 % of effluent oxygen concentration, showing obvious thermal effect caused by low-temperature oxidation of heavy crude oil. Both the increment in the specific surface area and the addition of quartz sand and detritus can promote the thermal release induced by low- temperature oxidation of heavy oil, thereinto, the specific surface effect of medium gives a small contribution to the thermal release of low-temperature oxidation.

Key words: quasi-adiabatic conditions, heavy crude oil, low-temperature oxidation, thermal effect, specific surface area, quartz sand
