摘要

研究人员对阿沙尔查油田和努尔拉特油田中不同年龄的古生代重油沥青质氧化破坏产物进行了研究。研究表明,这两种石油的沥青质在醋酸存在下被过氧化氢氧化后,会释放出闭塞化合物。在其成分中发现的化合物包括正构烷烃、甾烷烃、合烷烃和正构烷酸甲酯。泥盆纪沉积物中出现的 Nurlat 石油沥青质的一个特点是在烯烃化合物成分中存在正烷烃。X 射线衍射分析结果证实了沥青质结构中存在烯烃化合物。

COMPOSITION OF THE COMPOUNDS OCCLUDED BY ASPHALTENES OF HEAVY OILS
The products of oxidative destruction of asphaltenes of heavy Paleozoic oils from the Ashalcha and Nurlat oilfields differing in the age of host sediments have been studied. It is shown that oxidation of the asphaltenes of both oils by hydrogen peroxide in the presence of acetic acid results in the release of occluded compounds. The compounds identified in their composition include n-alkanes, steranes, hopanes and methyl esters of n-alkane acids. A peculiarity of the asphaltenes of Nurlat oil occurring in the Devonian sediments is the presence of n-alkenes in the composition of occluded compounds. The presence of occluded compounds in the structure of asphaltenes is confirmed by the results of X-ray diffraction analysis.
