1. Due to the frequent and large fluctuation of crude oil, it is not accurate to predict the adjustment range and trend of a new round of refined oil in the first four working days after price adjustment. Therefore, it is suggested that the predicted change range and trend on the fifth working day after the price adjustment should be taken as a reference for the new round of price adjustment.
2. According to the reform content of refined oil pricing mechanism of 2065 438+03. 3. 27, Zhuochuang Information tracked the prices of several crude oils that accounted for a large proportion of China's imports, and calculated the crude oil change rate and the corresponding domestic refined oil price adjustment range.
3.2065438+65438 2006+6543810 +3 In the Measures for the Administration of Petroleum Prices, when the average price of crude oil is less than 40 USD/barrel (inclusive), the domestic refined oil price will not be lowered.
Traditionally, crude oil is called crude oil. Dark brown viscous oily liquid with green fluorescence and special smell. It is a mixture of alkanes, cycloalkanes, aromatic hydrocarbons and olefins.
The main components are carbon and hydrogen, accounting for 83 ~ 87% and 1 1 ~ 14% respectively. There are also a small amount of sulfur, oxygen, nitrogen and trace elements such as phosphorus, arsenic, potassium, sodium, calcium, magnesium, nickel, iron and vanadium. Specific gravity 0.78 ~ 0.97, molecular weight 280 ~ 300, freezing point -50 ~ 24℃. Crude oil can be refined to obtain various products, such as fuel oil, solvent oil, lubricating oil, grease, paraffin, asphalt, liquefied gas, aromatic hydrocarbons and so on. , and provide fuel, raw materials and chemical products for all sectors of the national economy.

The pricing of the international crude oil market is based on the standard oil in the world's major oil-producing areas. For example, on the New York Futures Exchange, crude oil futures are based on "WTI" produced in West Texas, and all crude oils produced or sold in the United States are priced based on light and low sulfur WTI. Due to the strength of American super crude oil buyers and the influence of New York Futures Exchange itself, crude oil futures trading based on WTI has become the leader in global commodity futures trading volume. Generally speaking, this kind of crude oil futures has good liquidity and high price transparency, and is one of the three benchmark prices in the world crude oil market. When the public and the media usually talk about how many dollars the oil price has exceeded, it mainly refers to this price. However, more than two-thirds of the world's crude oil trading volume is not based on WTI, but on Brent crude oil in the North Sea, which is also light and low in sulfur. On June 23rd, 1988, the London International Petroleum Exchange (IPE) launched Brent crude oil futures, including northwest Europe, North Sea, Mediterranean, Africa, Yemen and other countries and regions, all based on this. Because the futures contract meets the needs of the oil industry, it is considered as a "highly flexible tool to avoid risks and transactions" and also ranks among the three major international crude oil prices.
London has thus become one of the three major international crude oil futures trading centers. Brent crude oil futures and spot market constitute Brent crude oil pricing system, covering up to 80% of the global crude oil trading volume. Even today when the price of crude oil in new york is becoming more and more important, about 65% of the global crude oil trading volume is based on Brent crude oil in the North Sea. The conversion relationship between tons and barrels is: 1 ton (crude oil) =7.33 barrels (crude oil), that is, a barrel is about 136 kg. Although there is a fixed conversion relationship between tons and barrels, because tons are quality units and barrels are unit of volume, the density of crude oil varies widely. Therefore, in crude oil trading, if different units are used for calculation, different results will be obtained.
