INTRODUCTION - Oil and gas in different layers of the earth's crust,
- Hydrocarbons among different - district pore and other rocks
- together with its gases lies at a depth of 1.2+2 kilometers. Earth
- oil, a black oily liquid, is found at the bottom.
- The Persian word "neft" means burning, igniting.
- The appearance of oil scattered in the sedimentary part of the earth's depths
- It is a dark oily liquid with a specific smell and different colors
- has a brown appearance.
The mechanism of formation of oil from organic residues is from them - The mechanism of formation of oil from organic residues is from them
- oxygen and nitrogen disappear, and carbon and hydrogen
- based on the meeting. The formation of oil in the earth's crust is the period when organic life began to develop widely, that is, approximately 350 + 400 years ago.
- started a million years ago.
- The composition of oil below 4.5+5 kilometers is light
- fractions are small, mainly gases and gas condensates
- collected b o iad i. Oil under the influence of pressure, temperature and internal changes
- can move great distances. Usually, several of the depths of the Earth
- It is important that it is located at a depth of ten meters to 5+6 kilometers
- is a mineral.
The average molecular weight of oil is 220+300 (sometimes 450+470 - The average molecular weight of oil is 220+300 (sometimes 450+470
- reaches up to) and the density of oil is 770+920kg/m3, and 830
- The type below kg/m3 is light, around 831+860 kg/m3 —
- average and above 860 kg/m3 - heavy oil. Oil
- heat of combustion 43000+45500 kDj/kg.
- Boiling oil due to the presence of organic substances in it
- not by temperature, but by the boiling point of a liquid hydrocarbon
- characterized by N oil is soluble in organic solvents, insoluble in water,
- but can form an emulsion with it.
- What kind of natural resources, including oil and gas
- to know the sources clearly, to estimate and in what geometrical form
- studying the location is an important task.
- Exact estimation of reserves is prospecting and prospecting carried out in the mine
- prepared based on the results.
- Physical properties and quality indicators of oil
- depends on the amount of hydrocarbons in it. If the oil contains
- if the amount of heavy hydrocarbons prevails, gasoline in such oils
- and the oil content is less, and the movement in the layer is also less
- will be slower.
