摘要
虽然石油和天然气都是流体矿产，但它们的物理性质有很大不同，诸如：密度、粒度、溶解度、表面张力、扩散性等等，从而引起它们在运移和聚集特征上也有很大不同，这些不同的特征决定了天然气勘探的时空领域比石油更广阔，然而却比石油更难于保存下来。
Although oil and gas both belong to the fluid mineral resources, they differ widely in their physical behaviour such as density, viscosity, solubility, surface tension and diffusivity etc, causing significant differences in their characteristics of migration and accumulation. These differences determine that the exploration for natural gas will have a wider time-space area than that for oil and that natural gas will be more difficult to preserve.
