Oil Exploitation N2 Nitrogen Generator

From the perspective of multiple oil reservoirs, nitrogen injection into oil reservoirs mainly has the following functions:

Maintain reservoir pressure

Keep the pressure of the oil and gas reservoir at or above its dew point pressure or bubble point pressure, or at the current pressure level, so that the oil and gas reservoir fluid can flow out smoothly.

Gravity drainage and immiscible flooding

According to the characteristics of low nitrogen density, inject it into the top of the structure or allow it to migrate to the top of the structure, enhance the role of downward displacement of reservoir fluid or gravity and stable miscible slug, and improve the production of oil and gas reservoir fluid.

Miscible flooding

The oil and gas in the oil and gas reservoir are displaced by the multiple contact miscibility of nitrogen.

Drive carbon dioxide slug

Nitrogen is used as the displacement fluid to remove the miscible slug formed by carbon dioxide and other solvents in the oil and gas reservoir.

Penthouse oil exploitation

High-pressure nitrogen can drive the trapped crude oil in the attic layer at the top of the structure into the production well.

Gas cap displacement

Injecting nitrogen into the best part of the reservoir can maintain or increase the reservoir pressure and simultaneously displace and produce gas cap gas.

Pipeline purging

Before the maintenance of flammable and explosive gas and liquid transmission pipeline, the residual gas and liquid in the pipeline must be purged. According to the actual situation of the pipeline, purge the pipeline with nitrogen of certain pressure and flow.

Fuel oil tank gas seal

The residual air on the top of the fuel tank is one of the main reasons for the fire and explosion of the tank. Filling nitrogen on the top of oil tank is the fundamental way to solve this problem. This method is also used for other liquid tanks.
