最重要的天然气来源是什么?煤、石油或其他?

通过热量和压力,煤和石油可以产生气体。但是最重要的物质是什么气体?有大量的海洋生物的关系(海洋生物)死亡,植物和树木的数量是由沙子或石油(海洋生物)或煤(植物)更能产生气体?

其他替代来源的贡献是什么?

回答

最重要的因素对石油成为气体不是一种物质,它的温度和压力。大多数水库都有不同程度的;拓普规定每个将形成的多少。知道的类型字段告诉你你应该期待什么,无论是自然宿主(黑金),或泥炭沼泽(油砂)。>地质学家通常指油的温度范围形式作为“油窗口”。最低温度下石油仍然被困在干酪根的形式。最高温度以上油转化为天然气通过热裂解的过程。有时候,石油形成极深可能迁移,成为被困在浅层次。阿萨巴斯卡油砂是这方面的一个例子。-[石油][1]石油在德克萨斯州,美国40%的原油来自何方,盖层下,陷阱一个“三层蛋糕一层水低于石油层,上面一层气体”[(Wiki)] [1]。 This type of reservoir will contain much natural gas. The oil sands of Canada, which has the largest mining operation by area in the entire world, extracts bitumen; aka: peat. To extract natural gas from oil sand it must be cracked, which costs money, as opposed to the freely available stuff under a capstone. >[Peat][2] forms in wetland conditions [terrestrial life, not aquatic], where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition. --- >A fossil fuel, [petroleum][1] is formed when large quantities of dead organisms, mostly zooplankton and algae [aquatic life], are buried underneath sedimentary rock and subjected to both intense heat and pressure. **TL;DR:** the good stuff comes from poorly decomposed aquatic life. The harder stuff comes from poorly decomposed plant life.... Apparently the dinosaurs *did not* all die and turn into oil. --- Apologies but, *the most important source* IMO would need to be determined by computing the amount of barrels produced, while knowing what type of field they came from. E.g., "Oil sands were the source of 62% of Alberta's total oil production and 47% of all oil produced in Canada." ([Wiki][3]) Now you just have to figure out how many barrels Canada produces, contrasted against the same information for every country or oil company throughout the entire world.

\ begingroup美元 “有时候,石油形成极深可能迁移和被困在浅层次。阿萨巴斯卡油砂是这方面的一个例子。”- I was under the impression that the Canadian oil sands were 'Peat' having formed in "wetland conditions". Perhaps it formed the normal way, but with nothing acting as a capstone it lost, and continually losses, all its gas. \ endgroup美元
