Background technology
Oil, also referred to as crude oil, are a kind of sticky, dark brown (sometimes a little green) liquid.Upper crustal is partly
There is petroleum storage in area.The property of oil is different because of the place of production, and range of viscosities is very wide, and freezing point difference is very big (30-60 degrees Celsius), boiling
Point range be normal temperature to more than 500 degrees Celsius, dissolve in a variety of organic solvents, it is water insoluble, but can with water formation emulsion.No
Crossing the composition and appearance of the oil in different oil fields can distinguish very big.Oil is mainly used as fuel oil and gasoline, fuel oil and
One of current primary energy most important in the world of gasoline composition.Oil is also many chemical industries such as solvent, chemical fertilizer, killed
The raw material of worm agent and plastics etc..During the long history that the earth constantly develops, there is " special " period, such as the Paleozoic Era and
In Mesozoic Era, after substantial amounts of plant and animal is dead, the organic substance for constituting its body is constantly decomposed, and is precipitated with silt or carbonic acid matter
The material mixings such as thing constitute sedimentary.Because deposit constantly accumulates thickening, temperature and pressure is caused to rise, with this mistake
The continuous progress of journey, sedimentary is changed into sedimentary rock, and then forms sedimentary basin, and this just provides basic ground for the generation of oil
Matter environment.The composition of crude oil mainly has：Oily (this is its main component), colloid (a kind of sticky semi-solid material), pitch
Matter (crineous or black brittle solid material), carbonaceous (a kind of nonhydrocarbon).Oil is mixed based on the hydrocarbon
