There are both connections and differences between natural gas and oil generation: oil is mainly formed in plutonic stage, which is caused by catalytic cracking, while the formation of natural gas runs through diagenesis, plutonic, epigenetic and metamorphic processes; Compared with the generation of oil, the generation of natural gas is more extensive, faster and easier in both the original material and the generation environment. All kinds of organic matter can form natural gas-sapropelic organic matter generates oil and gas, and saprophytic organic matter mainly generates gaseous hydrocarbons.

Natural gas is also a kind of energy, which is mostly associated with crude oil. The exploitation method is basically the same, but it is different in the final collection and processing. Compared with the smelting process of crude oil, natural gas is much simpler. After natural gas is mined, it can be used directly after canning, and crude oil has to be purified. In addition to crude oil can be used as raw materials for processing industrial materials such as rubber, natural gas can be equivalent to crude oil in combustion energy, and of course its inventory is also roughly equivalent to crude oil inventory, which in turn affects its price.
