How to exploit oil?

There are two main methods of oil production: self-injection oil production and artificial lifting. In the process of oil well development, after oil well testing, the appropriate production mode will be selected according to the reservoir physical properties and pressure of the oil well.

In actual production, oil wells with good reservoir properties and high pressure can be self-injected to the surface, that is, self-injection oil production. For oil wells with poor reservoir properties and low pressure, when local energy is not enough to lift oil and gas to the bottom, artificial energy should be supplemented for artificial lifting.

Flow production in oil wells usually goes through four flow processes:

(1) crude oil flows from the reservoir to the bottom of the well;

(2) from the bottom of the well along the shaft to the wellhead;

(3) The crude oil passes through the choke after reaching the wellhead;

(4) along the ground pipeline to the separator and metering station.

Extended data

The main components of petroleum are: oiliness (which is its main component), colloid (a viscous semi-solid substance), asphaltene (dark brown or black brittle solid substance) and carbon. Petroleum is a kind of colored flammable liquid with special smell, which is mainly composed of hydrocarbons.

Strictly speaking, oil is mainly composed of hydrocarbons composed of hydrogen and carbon. The chemicals that make up petroleum can be decomposed by distillation. Crude oil as processed products, including kerosene, benzene, gasoline, paraffin, asphalt and so on. Strictly speaking, oil is mainly composed of hydrocarbons composed of hydrogen and carbon. The four hydrocarbons with the smallest molecular weight are all gases.
