What are the factors that affect the international crude oil price?

Supply and demand, crude oil inventory, exchange rate factors, economic development, emergencies and climatic conditions.

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.

Extended data:

The main components of crude oil 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 products can be divided into six categories: petroleum fuels, petroleum solvents and chemical raw materials, lubricants, paraffin, petroleum asphalt and petroleum coke. Among them, the output of various fuels is the largest, close to 90% of the total output; There are the most varieties of lubricants, and the output accounts for about 5%.

Classification of crude oil

Classification by composition: paraffin-based crude oil, naphthenic base crude oil and intermediate base crude oil;

Classification by sulfur content: ultra-low sulfur crude oil, low sulfur crude oil, sulfur crude oil and high sulfur crude oil;

Classification by specific gravity: light crude oil, medium crude oil and heavy crude oil are divided into three categories.
