摘要
传统的油气运移地球化学示踪研究主要集中在各种生物标志化合物和含氮化合物。近年来,油气示踪研究中相关的示踪剂和分析技术呈多样化发展,除咔唑类含氮化合物以外,二苯并噻吩(DBTs)和二苯并呋喃(DBFs)也是良好的运移指标;储层自生矿物、稀有气体同位素和金刚烷等也可用于油气运移示踪,但其机理与应用指标还有待深入研究。傅里叶变换离子回旋共振质谱(FT-ICRMS)技术能够扩大化合物的检测范围,同时避免了传统分离过程对含氮化合物的影响,在油气运移示踪领域显示出广阔的应用前景。在油气运移示踪研究中,应正视各种方法或示踪剂自身的局限性,加强新的地球化学指标的运用,强调多指标参数的综合运用。
Previous studies on hydrocarbon migration with geochemical techniques mainly focus on biomarkers and nitrogen compounds.In recent years,the analysis and techniques for hydrocarbon migration have been diversified.In addition to the carbazole nitrogen compounds,dibenzothiophene(DBTs) and dibenzofuran(DBFs) are also good migration indicators.Authigenic minerals,rare gas isotopes and adamantane have been used to trace hydrocarbon migration successfully.However their mechanism and application indexes still need to be further studied.Fourier transform cyclotron resonance mass spectrometry(FT-ICR MS) shows great application prospect in the hydrocarbon migration tracing because it can expand the detection range of nitrogen compound and avoid side effect that occurred in traditional separation process.We should give concern to the limitations of various tracing methods,and adopt multi-index parameters to analyze the hydrocarbon migration comprehensively in the practice.
