利用含油流体包裹体可以获得与原油和源区常规分析同等质量的可靠地球化学数据,细致而又小心谨慎地对待各测试步骤(如样品清洗、背景空白等)是成功进行包裹体油气成分分析的基础,从技术上来说,每一分析步骤都具有挑战性,但如果我们能按步骤循序渐进,就不仅能够分析那些含有大量石油包裹体的样品(如当今或古油藏样品),而且可以测试含极少量石油包裹体的样品(如迁移路径或极古老岩石样品),包裹体中可被测试的碳氢化合物多种多样,包括低分子量的碳氢化合物、n-链烷、类异戊二烯、生物标志物、芳香族碳氢化合物等。流体包裹体内石油成分分析在地质上有广泛应用,比如可以更好地重建储集区石油重注史、确定盆地中以前未知的活性源岩,在储集区内由生物降解造成的石油再造和(或)水洗作用经常被抹去,流体包裹体分析则可以解释储集区复杂成油阶段,当然更可以去除钻孔泥浆添加剂或其他污染物的影响。此外,也可以获知地球早期生物圈碳氢化合物的组成及多样性,以及在勘探区或盆地进行二次迁移路径填图。
Using oil-bearing fluid inclusions, reliable geochemical data of the same quality as crude oil and conventional analysis of source areas can be obtained. The careful and careful treatment of each test step (such as sample cleaning, background blank, etc.) is successful in the analysis of oil and gas composition of the inclusion Fundamentally, each of the analytical steps is technically challenging, but if we can step-by-step we can analyze not only those samples that contain large amounts of petroleum inclusions (such as present or paleo-reservoir samples), but also the Samples of very small petroleum inclusions (such as migration paths or very ancient rock samples), a wide range of hydrocarbons that can be tested in inclusions, including low molecular weight hydrocarbons, n-alkanes, isoprenoids , Biomarkers, aromatic hydrocarbons and the like. The petroleum composition analysis in fluid inclusions is widely used in geology, for example, the reconstruction of oil refilling history in the reservoir area can be better, the previously unknown active source rock in the basin can be identified, the petroleum rebuilding caused by biodegradation in the reservoir area, (Or) water washing is often erased, fluid inclusion analysis can explain the complex oil into the reservoir stage, of course, more can remove drilling mud additives or other pollutants. In addition, the composition and diversity of hydrocarbons in the Earth’s early biosphere and the mapping of secondary migration paths in exploration areas or basins can also be obtained.
