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.     

Determination of tectonic background for sedimentary basin from sandstone geochemistry

The chemical composition of sedimentary rocks is mainly controlled by source rocks. Through examining chemical composition of terrigenous rocks, the tectonic evolution of a sedimentary basin can be modeled. The Turpan Basin belongs to a continental sedimentary basin and its source rocks are derived from the upper continental crust.     

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.

煤中前沥青烯与沥青烯性质的研究

煤的溶剂抽出物中前沥青烯与沥青烯的质量之比随煤化程度增加而增加。原位热解红外光谱研究结果表明,它们的热稳定性与其结构参数有关,芳香度高,甲基取代结构多的前沥青烯比沥青烯的热稳定性好。前沥青烯与沥青烯在溶剂分级过程中表现出的溶解性与其结构参数无必然联系,而与其酸碱组分间的氢键强度有关。前沥青烯中酸碱组分间的氢键强度为５．１５～３０．９ｋＪ／ｍｏｌ;沥青烯为＜５．１５ｋＪ／ｍｏｌ。     

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。
