摘要

摘要: 采用负离子电喷雾（ESI）—傅里叶变换离子回旋共振质谱（FT-ICR MS），分析了渤海湾盆地济阳坳陷樊页1井页岩油和临近页岩油产层的两种不同岩相的岩心抽提物组成，重点研究其中吡咯类含氮化合物分子组成的差异。页岩油和岩心抽提物杂原子化合物以N₁类为主。对比高分辨质谱图全貌和指纹细节、3个样品中N₁类化合物的等效双键数及碳数分布以及N₁类化合物的平均分子量，均揭示页岩油中吡咯类氮化物组成与相邻层位的纹层状页岩抽提物组成类似，而与块状页岩抽提物中该类化合物组成差异较大。电喷雾—高分辨质谱具有超高的分辨率，能有效分析不同类型样品中杂原子化合物的精细分子组成差异，可为陆相页岩油近源示踪研究提供借鉴。

Abstract: The composition of shale oil and neighboring shales with different lithofacies in well FY 1 in the Jiyang Depression of Bohai Bay Basin was analyzed with negative-ion electrospray ionization (ESI) and Fourier transform-ion cyclotron resonance mass spectrometry (FT-ICR MS). The molecular compositions of pyrrole nitrogen compounds were compared. The heteroatom compounds of shale oil and two core extracts were mainly N₁ compounds. The high resolution mass spectrum and fingerprint details, the DBE and carbon number distribution of N₁ compounds, and the average molecular weight of N₁ compounds of three samples all showed that the composition of pyrrole nitrides in shale oil is similar to that of lamellar shale extracts, but different from the massive shale extracts. The ESI and FT-ICR MS has an ultra-high resolution and can effectively show the fine molecular composition differences of heteroatomic compounds in different types of samples. The analysis results can provide a reference for the near source tracing of terrestrial shale oil.
