Oil can be bought in the futures market. Buying crude oil futures in China requires opening a crude oil futures account. Domestic crude oil futures have been listed, and the listing time of crude oil futures is 2065438+March 26th, 2008. The futures account needs more than 500,000 crude oil, has commodity futures trading records above 10, and has passed the basic test of crude oil futures.

Introduction to petroleum:

1. The properties of petroleum vary from place of origin, with a density of 0.8-1.0g/cm3, a wide viscosity range, and a great difference in freezing point (30-60℃), with boiling points ranging from normal temperature to above 500℃. It is soluble in various organic solvents, insoluble in water, but can form emulsion with water. But the composition and appearance of oil in different oil fields can be very different. Petroleum is mainly used as fuel oil and gasoline, which constitutes one of the most important secondary energy sources in the world.

2. Petroleum is also the raw material of many chemical industrial products, such as solvents, fertilizers, pesticides and plastics. 88% of the oil produced by 20 12 is used as fuel, and the other 12% is used as chemical raw materials. In fact, oil is a non-renewable raw material.

Second, the nature of oil:

1. The representative Daqing oil belongs to low-sulfur paraffin-based oil, and most of the oil produced is low-sulfur paraffin-based oil. This kind of petroleum has low sulfur content, high wax content and high freezing point. It can produce high-quality kerosene, diesel oil, solvent oil, lubricating oil and industrial paraffin, and straight-run gasoline has good lead sensitivity.

2. Some petroleum has high sulfur content and high gum content, which belongs to sulfur-containing paraffin base. Its straight-run gasoline fraction has high yield and good lead sensitivity. Diesel oil fraction has high cetane number, high flash point, high sulfur content and high acidity, and can be refined to produce light diesel oil and special diesel oil. The viscosity index of some components in lubricating oil fraction is above 90, which is a good raw material for producing internal combustion engine oil.

3. Some oils have low sulfur content and high wax content, and belong to the middle group of low sulfur naphthenes. Its gasoline fraction has good lead sensitivity and is also rich in naphthenes and aromatics, so it is also a good raw material for catalytic reforming. The freezing point and sulfur content of diesel fraction are low, and the acidity is high, so the product needs alkali washing. Vacuum residue can be oxidized to produce petroleum building asphalt.

4. Other low pour point oil has low sulfur content and low wax content, and belongs to the middle group of low sulfur. It is suitable for producing some low pour point products with special properties and can extract naphthenic acid at the same time. It is a rare and precious resource.
