Compared with developed countries, China's gas supply industry started late, and the main gas distributed is gas, liquefied petroleum gas and natural gas. Since 1990s, China's natural gas supply has greatly increased. Among them, the supply of artificial gas is in a relatively slow growth stage after a substantial increase of 1990, because of its shortcomings such as large pollution and strong toxicity.
The supply of liquefied petroleum gas remained stable due to the rising oil price. The price of natural gas with the same calorific value is 30%-50% cheaper than gasoline and diesel, and the economy is obvious. At the same time, the country pays more and more attention to environmental protection, and the market demand for clean energy continues to grow. As a clean, efficient and cheap energy, natural gas consumption is developing rapidly.

Due to the long-term high international oil price, the global demand for cleaner energy-natural gas is growing strongly. 2 1 century is the century of natural gas. The sustained development of China's economy and the further adjustment of energy policy have greatly promoted the development of China's natural gas industry. At present, in the world energy consumption structure, oil accounts for 39.7% and natural gas accounts for 23.2%.
However, the proportion of natural gas in China's energy consumption structure is only about 2.5%, far below the world average and the Asian average 10. 1%. Therefore, at the beginning of the 20th century, China took the development and utilization of natural gas as the focus of optimizing the energy structure and upgrading the petroleum industry, and will increase the energy consumption proportion of natural gas to about 5.3% around 20 10.
It will reach about 12% in 2020. By then, the application of natural gas in China will probably approach or surpass that of oil, and China's energy structure will achieve the goal of "high efficiency, economy, cleanliness and safety".
