| 摘 要： | 近年来的研究工作表明,流体不仅存在于地球表层及上地壳,而且也大量存在于地球深部(下地壳及地幔),其成分以H2O和CO2为主。由于特定的温度和压力条件,流体均呈超临界状态存在,它们是能量与物质的运移载体。由于其独特的性质,因而它们不仅参与了深部油气的无机生成,而且也对油气的富集及向上运移成藏起了重要作用。

| Abstract: | In recent years, more and more researches have proved that fluids are not only in upper crust but also in lower crust and mantle, and they are mostly composed of H 2O and CO 2. Because of the particular pressure and temperature conditions in deep Earth, they are under supercritical state and show particular physical and chemical characters that are different from general fluids. They are important transportation media of matter and energy and play important roles in the evolution of Earth. And they also play important roles in the origin and migration of oil and gas. On the other hand, they are related to inorganic origin of oil and gas, and they also produce an important effect in enrichment and migration of petroleum. |
