| 摘 要： | 从岩相学、成岩作用和流体地质学的角度出发,阐述了沉积岩包裹体发育分布的时空规律和流体组成的特殊性。分析了包裹体油气地质研究中值得注意的关键问题:一是包裹体的生源属性,准确区分不同情况下的成岩包裹体和继承包裹体、成岩自生矿物与物源沉积矿物、同源流体和异源流体;二是包裹体的多期捕获,辨别包裹体同源多期和异源多期的复杂情形以及包裹体期次划分的根本依据;三是包裹体后生变化(再平衡)的鉴别和原始温度的恢复。最后指出在包裹体观察和实验测试中应注意的重要事项,以使包裹体的分析研究符合客观地质实际。

| Abstract: | The paper expatiated on space time distributing rules and composition characteristics of inclusions in sedimentary rocks according to analysis of petrography, diagenesis and hydrogeology. The key problems were analyzed to apply study of inclusion in oil gas geology. The first problem was an autogenecity of inclusion. The diagenetic inclusion and successive one,diagenetic autogenetic mineral and clast grain from sedimentary rocks, cogenetic fluid and accidental fluid should be distinguished accurately under different circumstances. The second problem was multiperiodity of inclusion. It was necessary to recognize multiperiods of inclusions from same source and different source. Meanwhile, the essential standard to partition periods of inclusions was expounded. The third problem was distinguishment of inclusion re equilibrium and recovery of primal temperature. Finally, the important occurrences were pointed out in observation and experiment of inclusion, thus the research results of inclusion might accord with the geological facts. |
