稳定同位素地球化学在盆地流体分析中的应用现状及发展前景

Present application situation and prospect of stable isotope geochemistry during basin fluid analysis.

稳定同位素地球化学的迅猛发展,有效地解决了许多地质难题。该文从原理出发,综合前人的研究,论述了其在盆地流体成岩矿物年代学分析、流体场特征分析、地层水成因演化研究、储层非均质性研究、流体活动示踪、古流体温度、盐度分析、海相、湖相区分、成岩环境分析等方面的应用。提出了在理论方法、技术手段和数据解释上存在的一些问题;展望了该学科在方法标准、技术手段和测试仪器方面的发展前景。

Remarkable progress in stable isotope geochemistry solved many difficult geological problems effectively. Its applications were discussed in the analyses and research of basin fluid diagenetic mineralogical age,fluid field character, evolution of formation water origin, reservoir heterogeneity, fluid movement trace, temperature and salinity of ancient fluid, distinguishing between sea facies and lake facies, diagenetic environment. Some questions are brought forward on theoretical method,technical tool and data interpretation. At last, prospect of method criterion, technical tool and testing instruments are forecasted.
