每年创造了多少油?

2014 - 04 - 26 - t05:29:59z

我们都知道石油是一种不可再生资源在人类时间尺度。然而,我目前从事一项活动的高中生教他们预测人类可以持续多久开采石油耗尽之前(和可持续的萃取率是什么)。 为此,有人知道大约每年创造了多少油,(在整个地壳,无论如何无法访问)?

我不能提供号码,但希望自己合理的轮廓计算: 石油形成所需要的只是一个在沉积盆地生油岩带到正确的深度和石油迁移到母岩。如果是经济上有利可图(见脚注)进入全球储备计算。(石油沉积学“Zimmerle h . Zimmerle) < img src = " https://i.stack.imgur.com/g94p1.jpg " alt = "石油窗口”> 所有你需要计算体积的石油产量是一个估计目前在这些条件下的主岩沉积盆地。 < img src = " https://i.stack.imgur.com/avQQz.gif " alt = "沉积盆地" > 你可以看到有一个惊人的沉积盆地面积覆盖地球,和所有这些盆地石油生成条件下有一定的体积。 你可能还需要一个粗略的估计能出来多少油的平均生油岩,多少会被困在经济上有利可图的母岩陷阱。也许一个因素考虑盆地类型,也有助于提高计算(挤压盆地也有很多反传统形式的陷阱,而张性盆地倾斜床陷阱)。 我觉得地球的石油库存总量可能是一个逻辑函数。一旦所有的石油陷阱填满所有的过度石油是输给了迁移或过多的热量。空陷阱将意味着石油会找个地方积累。所以这可能是一个稳定系统(但不是human-time-scale,但让我们看看我们持续多久)。 回答。我认为这将产生一个数量级很可能有人已经这些计算,我想看到这些数字。 脚注:石油,像所有资源,遵循矿业经济学。如果你赚钱,你我的,如果你宽松的货币,你离开。这也意味着,如果可以赚更多的钱,还有更多存款值得付出努力。 Calculations with today's reserves are almost useless, because they can't predict what people will be willing to pay for oil in the future. Even if mining becomes unprofitable, we might produce synthetic oil, just because it is a convenient chemical (energy stored in relation to mass, diffusivity, and danger). We kind of already have that with rapeseed oil, which sadly can get a better price to power rich countries cars, than feed poor countries people.

根据这个威斯康辛大学参考http://whyfiles.org/100oil/2a.html < a href = " http://whyfiles.org/100oil/2a.html " > < / > 12.5%的石油和天然气从生物体生活在5到3400万年前。 如果我们把估计的总在人类开采石油4万亿桶,这是500金或银桶。 所以粗略估计可能是每年5000亿桶每3000万年或17000桶。

每年约80000桶吗?

One way to have a rough estimate is to assume that the rate of oil formation has not changed since the Mesozoic. The vast majority of oil reservoirs formed during the last 250 million years. All we need to know is the total oil formed in that period:

By 2009 we had consumed CB2009 = 1.0e11 to 1.35e11 oil tonnes. [https://phys.org/news/2009-05-oil.html]

The proven (90% chance of recoverability) reserves at that time were PR2009 = 2.2e11 tonnes. [http://www.forbes.com/sites/judeclemente/2015/06/25/how-much-oil-does-the-world-have-left/#1688f3955dc5]

The unproven (known reservoirs that are non profitable under present economic and technological conditions), may account for 4 times the proven reserves. Let's label that factor as UPFC=4.

But the biggest uncertainty comes from estimating the unknown oil reserves (reservoirs that are not yet known). Estimates are disperse, not even providing a precise order of magnitude. Depends, for example, on how you evaluate this figure:

If you assume that we are around half way of discovering all oil reservoirs accumulated on the Earth's sedimentary basins, then you just have to divide by the 250e6 years they took to form.

The average rate of oil formation is therefore:
(CB2009 + PR2009) * UPFC * 2 / 250e6 = 11,200 tonnes/year = 80,000 barrels/year

Note that this is the average Mesozoic+Cenozoic oil formation rate minus the average oil degradation rate (oil is also lost after its formation through different natural processes).
