激光测油液污染度的原理及其测定装置

选取了光测法检测油液污染度,在适合的波段内,油样对光均具有一般吸收,透光率相对稳定且较大;油样粘度的变化对透光率影响较小,而油液颜色的深浅对透光率有影响。导出了定量分析油液污染程度、消除油液颜色影响和提高检测精确度的理论公式,讨论了影响检测结果的因素及相应的解决方法．     

Carbazole-type compounds in crude oils

Carbazole-type compounds were analyzed using GC and GC-MS-MS. A relatively high concentration of carbazole-type compounds was detected in crude oils of different types (marine and non-marine) and different maturities (low mature and mature) in Tarinl. Liaohe and Keilu basins. The results suggest the ratios of 1, 8-dimethyl-/2, 7-dimethylcarbazole and benu, [a] carbazole/benzo [e] carbazole might be taken as petroleum migration parameters.     

Origin of immature sulfur-rich oil in Jianghan oil field

Chemical structure of immature sulfur-rich kerogen and composition of immature sulfur-rich crude oil in Jianghun oil field have been studied. In molecular level, crude oil differs from thermolysed and chemolysed products of kerogen but does resemble the bitumen in immature sulfur-rich source rock. Therefore, immature sulfur-rich oil may be derived from the expelling of bitumen rather than from thermal cracking of kerogen.     

Comprehensive evaluation of mechanism of “chimney effect” using principles of magnetism, geochemistry and mineralogy

Study of forming mechanism of "chimney-effect" (CE) has important significance for basic theory and applications of non-seismic geophysical and geochemical methods locating oil/gas reservoirs. The theoretical basis of comprehensive evaluation of mechanism of CE using principles of magnetism, geochemistry and mineralogy has been reviewed, with the problems to be solved: (ⅰ) study for the relationship between process of oil/gas migration and geochemical field; (ⅱ) analysis of genesis of magnetic, geochemical and mineralogical anomaly; (ⅲ) interpretation of surface soil magnetism and geochemical anomaly combined with seismic data.     

影响油气运移的应力场地温场渗流场耦合的双重介质模型

地应力场、地温场和渗流场是影响油气运移的主要因素。以此为基础,研究了含油气盆地双重介质体系内流体与岩体相互的力学作用关系,提出了双重介质体系内渗流场、岩体地应力场和地温场耦合的非线性动力学模型。     

不同贮藏条件下鳗骨油氧化特性的研究

研究了室温下（15℃）鳗骨油在空气中的自氧化速度,以及温度和贮藏条件对鳗骨油氧化速度的影响。实验所设的温度梯度分别为6℃、15℃、35℃,贮藏条件分别是敞口,密封（蜡封）和用N2驱除氧气后密封保存。实验结果显示,室温下鳗骨油在空气中的自氧化速度,敞口存放4天,过氧化值就已超过0.15;温度和贮藏条件对鳗骨油的氧化速度有显著影响,驱除氧气低温贮藏可以有效地防止鳗骨油的氧化。
