Before 1980s’，the US，Western Europe and Japan were playing “Big Three” in the world oil industry，they produced 80% of total petrochemicals production of the whole world. As the development of oil industry，the world is changing too.

Oil is called “the blood of industry” and “critical material”. And now oil is becoming the most important good in the ocean shipping due to unbalanced situation of reserve，exploitation and consumption. And we have to say the oil pipeline is the “vessel” if the oil is “blood”. The international oil market and world economic would be under a devastating damage if the oil pipeline is not working even a few minutes. So，most countries are playing the “house of cards” to control the oil market，the game of supply and demand is beginning.

We all know that China needs oil. The purchase and the supply chain is not only related to the economic development，but also directly affect the national security. And now the reform is go in China，the entire environment is changing because of transformation of the economic structure. In order to run better，the oil industry have to change to adapt new situation. So we can see massive renovation in China’s oil industry like monopoly rights released，operating reform，equipment dating，open market for crude oil，etc.
