针对新疆J区块稠油开展了恒温静态氧化管实验
通过分析氧化后产出气及原油组分的变化来研究温度、压力、石英砂和岩屑对稠油低温氧化特性的影响。实验结果表明:相比70℃
稠油在110℃条件下的平均耗氧速率增加了1.42%/d;压力从10 MPa增加至30 MPa时
CO+CO
2
生成量增加了2.13%;石英砂和岩屑均能促进稠油氧化反应进程;与原油相比
加入石英砂和岩屑后耗氧量分别增加了1.71%和4.08%;岩屑对稠油低温氧化反应的促进作用主要来自岩屑的催化作用。采用TG-DSC同步热分析仪研究了原油氧化行为
并通过Arrhenius氧化动力学模型计算了活化能。结果表明:稠油在低温氧化阶段具有较低的反应活性
该阶段活化能仅为18.09 kJ/mol
远低于燃料沉积和高温氧化阶段的活化能（84.58 kJ/mol和113.39 kJ/mol）。
The static isothermal oxidation tube experiments were carried out for heavy crude oil in J block of Xinjiang Oilfield. The effects of temperature
pressure
quartz sand and detritus on the low temperature oxidation（LTO） characteristics of heavy crude oil were investigated by analyzing the alterations in the produced gas and SARA（saturate
aromatic
resin and asphaltene） fractions of oxidized oil. The results showed that the awerage oxygen consumption rate of the crude oil was increased by 1.42 % per day at 110 ℃ relative to that at 70 ℃. When the pressure was increased from 10 MPa to 30 MPa
the production of CO+CO
2
was increased by 2.13 %. Both quartz sand and detritus promoted oxidation reaction on the heavy oil. The oxygen consumption increased by 1.71 % and 4.08 % after the addition of quartz sand and detritus relative to the crude oil. The promotion of detritus on LTO reactions of heavy crude oil mainly derived from the catalytic effect of detritus. The oxidation behavior of the crude oil was studied by the TG-DSC
and the activation energy was calculated by Arrhenius kinetic model. The results indicated that heavy crude oil had poor reactivity in the LTO stage
and the activation energy in the LTO region was only 18.09 kJ/mol
which was much lower than that in the fuel deposition and high temperature oxidation stages（84.58 kJ/mol and 113.39 kJ/mol）.
