A PSA nitrogen generator, short for Pressure Swing Adsorption (PSA) nitrogen generator, is a device that separates nitrogen from air based on the pressure swing adsorption principle, using molecular sieve adsorbents as the core. It consists of an air compressor, a pretreatment system (including filters, dryers, etc.), adsorption towers filled with molecular sieves, and a control system. PSA nitrogen generators are celebrated for their advantages such as high nitrogen purity, low operating costs, and simple operation. They are widely applied in industries like oilfields, chemicals, and food preservation.
Nitrogen is a standard gas used to re-pressurize oil and gas from large wells/natural gas zones. Leveraging its inherent properties to maintain reservoir pressure, the technologies of mixed-phase and immiscible oil-gas-gravity drainage can greatly improve oil recovery rates, which is of great significance for stabilizing oil production and increasing oil output.
The reason why high-pressure nitrogen can help improve oilfield development efficiency is mainly based on the following points:
- Under certain conditions, nitrogen can enter wet fractures and displace the remaining oil therein. This is something that water injection cannot achieve, because there is a gravity difference in oilfields.
- Through the gravitational separation of the oilfield, gravity can be used to discharge the residual oil in the fractures.
- Nitrogen can utilize the oil displacement effect under surface separation conditions, dissolve in crude oil, expand the volume of crude oil, and reduce the remaining oil saturation of the formation.
- Change the fluid flow direction and drive the remaining oil in the fracture channels.
- Remaining oil: Due to the gravitational separation of oil and gas, the remaining oil is not affected by the injected water from the upper part of the production well.
In addition to improving oilfield development efficiency, the inert property of high-pressure nitrogen can also be used for gas collection and pipeline system purging, which can prevent the combustion of flammable gases and the corrosion of underground oil pipelines.
Based on the value of nitrogen in oilfield development, the selection of nitrogen sources also needs to be professional. It is recommended to use a PSA nitrogen generation system, which is economical and reliable, with low maintenance, few infrastructure requirements, and movable features, making it more favored by Party A compared to other nitrogen sources.
