长期以来人们都认为油气生成的过程相当漫长,通常要持续数百万年。因此,石油和天然气是不可再生的一次性能源,采一点就会少一点,油田采到一定程度就得枯竭和废弃。可是,目前的一些现象说明,油气形成的时间要短得多。现已查明,在很多老油田的废弃油井上,常发现重新出油。同时,在一些正在开采的油井上,其累计采油量已超过油田的原始储量。根据这些现象和其它的一些资料,有人做了这样的假设:油气的生成要简单得多和快得多。如果这一假设成立,其意义将
For a long time, people think that the process of hydrocarbon generation is quite long, usually lasting millions of years. Therefore, oil and natural gas are non-renewable one-off energy sources, and they will be a little less, and the oil fields will have to be depleted and discarded to some extent. However, some of the current phenomena show that oil and gas formation takes much less time. It has been found that oil is often found in abandoned oil wells in many old fields. At the same time, the cumulative oil production in some of the wells being mined exceeds the original reserves of the field. Based on these phenomena and other sources, one has made the assumption that oil and gas generation is much simpler and faster. If this assumption is established, its significance will be
