How natural gas is formed
The main component of natural gas is methane gas (or compound) and a carbon atom composed of four hydrogen atoms. Millions of years ago, the remains of plants and animals. The decaying animals and plants are called organic compounds. As time goes by, the rocks are altered and filled with organic materials. Pressure and heat change some of this organic material into coal, oil (oil), and natural gas
Therefore, the genesis of natural gas is various. It is concluded that the origin of natural gas can be divided into biogenic gas, oil type gas and coal type gas. In recent years, inorganic gas especially non hydrocarbon is highly valued, here be briefly introduced, finally understand the various causes of discrimination method of gas
Compared with the generation of oil, whether it is raw material or production environment, natural gas in Chengdu is more widespread, more quickly and more easily, various types of organic matter can form natural gas -- sapropel type organic matter both source and angry, rot Zhixing organic matter mainly produce gaseous hydrocarbon
The oil and natural gas generation process have both similarities and differences: the oil is mainly formed in the catagenetic stage, caused by catalytic cracking, and the formation of natural gas passes through the diagenesis, plutonic metamorphism, after until the beginning
