摘要
80年代以来,流体包裹体研究已发展成为一种重要的油气研究手段,流体包裹体的成分测试及应用是其中的一部分。成分测试方法可以分为三大类,即非破坏性单个包裹体的成分分析(如红外光谱等)、破坏性单个包裹体成分分析(如激光等离子光谱质谱等)和破坏性群体包裹体的成分分析(如色谱质谱等)。不同世代及同一世代不同空间的流体包裹体的成分反映了油藏化学成分的时空变化特征,这种成分特征为油气源的对比提供了重要线索,而且包裹体中气体成分还可用于成岩和成藏温压条件的估计。除有机成分以外,流体包裹体的离子成分用于研究盆地蒸发岩的形成过程及确定古介质水的特征取得了重要进展。流体包裹体成分研究的主要问题在于:样品制备过程中可能造成污染;目前各种分析方法本身的精度和准确度都有一定局限性;测试过程中可能会引起包裹体成的改变。
Fluid inclusion has played an important role in the study of oil and gas since 1980's. Fluid inclusion component analysis andapplication are major parts of the study. The analysis method includes undestroyed single inclusion analysis (FTIR),destroyed single inclusion analysis (L-ICP-MS) and destroyed group inclusion analysis (GCMS). The component variation ofinclusions with formation stages and the sampling locations implies that the component of oil and gas in traps varies spatiallyand temporally. It is an important clue to study oil and gas sources. Gas component of inclusions can be used to estimatetemperature and pressure conditions in the process of oil generation and migration. Some advances in applying ion componentof fluid inclusions to study the formation of evaporate and ancient water have been made in recent years. Some problems exitin the study of fluid inclusion, which include sample pollution, limitation of different analysis methods and component changesin the process of analyzing.
