自然界中的油气显示多种多样,色彩纷繁。是广大石油地质工作者重要的研究方面。天然油气显示按其产出状态一般可分为气态、液态和固态三种。一般说来,气态和液态的油气显示由于是沿裂隙或断裂渗出地表,运移方式较为单一,在野外观察油花、油膜以及特殊的气味又都很直观,通过分析对比周围的地质情况,研究这两类的产出状态相对讲要比较容易;而固态含油显示的表现形式则要复杂得多。因为它是液
Oil and gas in nature show a wide range of colors. It is an important research area for the majority of petroleum geologists. Natural gas shows that its output can be divided into gas, liquid and solid state. In general, the gas and liquid hydrocarbons show that because of the exudation of the surface along the fissures or faults, the migration mode is relatively simple. In the field, it is very intuitive to observe the oil flower, the oil film and the special odor. By analyzing and comparing the surrounding geological conditions, It is relatively easy to study the state of output of these two categories, whereas the manifestation of solid-state oil is far more complex. Because it is liquid
